/******************************************************************************
TMS320C66xx KeyStone Multicore DSP Software Development Kit (SDK). Rev 2A.
Definitions, macros and API functions for DSP Environment.
(C) MicroLAB Systems, 2015
http://www.mlabsys.com
ftp://ftp.mlabsys.com
email: techsupport@mlabsys.com
Description:
------------
This file contains definitions, macros and API functions for KeyStone
Multicore DSP environment and must be included in the user C-application.
DSP Software Development Kit library is based on TI Chip Support Library
(CSL), so it's needed to add CSL libraries into the project along with DSP
Software Development Kit library.
Note that C66xx CorePac interrupt controller (INTC) functions are not
included in this DSP Software Utilities library.
It's delivered as a separate library from the remaining DSP Software
Utilities. When using an embedded operating system that contains interrupt
controller/dispatcher support, do not link in the INTC library.
For interrupt controller support, SYS/BIOS users should use
the HWI (Hardware Interrupt) and ECM (Event Combiner Manager) modules
supported under SYS/BIOS v5.21 or later.
Revision history:
-----------------
rev.1A - 2014, initial release for C6678 DSP.
rev.1B - 2015, fixed minor bugs.
rev.1C - 2015:
- changed C66XX_init_ddr3() DDR3 initialization
function;
- added DSP chip-level (CPINTC) interrupt controller
functions;
rev.2A - 2015, totally redesigned DSP SDK;
Notes:
------
1. This C-header file is an include file for TI C6xxx C/C++ Code
Generation Tools, which must be invoked to compile code for C66xx DSP
platform.
2. The following additional libraries should be included:
TI Chip Support Library (CSL) (ti.csl.ae66) should be included in
Linker options (this library is located at
$(TI_PDK_C6678_INSTALL_DIR)\packages\ti\csl\lib).
3. This file is best viewed with the TAB setting set to '4'.
4. This header file is externally controlled from user C-code by run-time
compiler keys definitions in order to apply DSP-type specific
definitions to refer to particular definitions included for different
DSP type:
__C66XX_SELECT_C6678_DSP__
- if defined in user code prior inclusion of this header file,
then DSP-type specific definitions are applied to C6678 DSP

TORNADO AMC modules Software Development Kit (SDK). Rev 4A.
Definitions, macros and API functions for DSP Environment.
(C) MicroLAB Systems, 2014-2017
http://www.mlabsys.com

Description:
------------
This file contains definitions, macros and API functions for TORNADO AMC
modules on-board DSP environment and must be included in the user
C-application for TORNADO AMC modules.
Revision history:
-----------------
rev.1A - 2014, initial release for TORNADO-A6678 board rev.1A.
rev.1B - 2015, fixed some bugs.
rev.1C - 2015, added support for TORNADO-A6678 board rev.1B:
- updated DSP external control registers area;
- updated TA66XX_init_dsp() DSP initialization
function;
- added MMC-to-DSP communication functions in DSP
I2C functions.
rev.2A - 2015, totally redesigned SDK for TORNADO-A6678 board rev.1B;
rev.3A - 2016, added support for TORNADO-A6678/FMC board rev.1A;

- added support for TORNADO-A6678/FMC board rev.1B;
rev.4A - 2017:
- added support for TORNADO-AZ/FMC board rev.1A;
Notes:
------
1. This C-header file is an include file for TI C6xxx C/C++ Code
Generation Tools, which must be invoked to compile for C66xx DSP
platform.
2. This file is best viewed with the TAB setting set to '4'.
3. This library uses dynamic memory allocation in erase FLASH functions,
so user should provide enough memory area for dynamic memory allocation
(-heap parameter) and place the section (.sysmem) in the corresponding
memory area in linker command file.
The max requested memory allocation block length is up to FLASH memory
sector length in bytes (128 KB).
4. This header file is externally controlled from user C-code by run-time
compiler keys definitions in order to apply board-type specific
definitions to refer to particular definitions included for different
board type:
__TA66XX_BC_USE_BIOS__
- if defined in user code prior inclusion of this header file,
then TI SYS/BIOS modules(HWI (Hardware Interrupt) and ECM
(Event Combiner Manager)), will be used to support
C66xx CorePac interrupt controller (INTC).
TI INTC Chip Support Library (CSL) should be used in case
NO embedded operating system is used in user application.
DEFAULT is NOT DEFINED, so CSL INTC library will be used
to support C66xx CorePac interrupt controller.

The 'targetConfigs' folder contains target-configuration (.ccxml) files, automatically generated based
on the device and connection settings specified in your project on the Properties > General page.
Please note that in automatic target-configuration management, changes to the project's device and/or
connection settings will either modify an existing or generate a new target-configuration file. Thus,
if you manually edit these auto-generated files, you may need to re-apply your changes. Alternatively,
you may create your own target-configuration file for this project and manage it manually. You can
always switch back to automatic target-configuration management by checking the "Manage the project's
target-configuration automatically" checkbox on the project's Properties > General page.

The 'targetConfigs' folder contains target-configuration (.ccxml) files, automatically generated based
on the device and connection settings specified in your project on the Properties > General page.
Please note that in automatic target-configuration management, changes to the project's device and/or
connection settings will either modify an existing or generate a new target-configuration file. Thus,
if you manually edit these auto-generated files, you may need to re-apply your changes. Alternatively,
you may create your own target-configuration file for this project and manage it manually. You can
always switch back to automatic target-configuration management by checking the "Manage the project's
target-configuration automatically" checkbox on the project's Properties > General page.

/* own special types that can be mapped to actual data types by this */
/* file to guarantee consistency in the interface and functionality. */

Microsoft's Azure RTOS ThreadX for TMS320C667x
Using the TI Code Composer Tools
1. Installation
TI Code Composer Studio and the TI MCSDK must be installed prior to
building ThreadX. The following links can be used to download these
packages:
http://processors.wiki.ti.com/index.php/Download_CCS
http://software-dl.ti.com/sdoemb/sdoemb_public_sw/bios_mcsdk/latest/index_FDS.html
It is assumed the tools are installed in the default directories:
CCS path by default - c:\ti\ccsv(version number)
MCSDK path by default - c:\ti
If the packages are installed in different directories, the ThreadX project
settings must be adjusted.
2. Open the Azure RTOS Workspace
In order to build the ThreadX library and the ThreadX demonstration first open
the Azure RTOS Workspace inside your ThreadX installation directory.
3. Building the ThreadX run-time Library
Building the ThreadX library is easy; simply import the CCS project file
"tx" and then select the build button. You should now observe the compilation
and assembly of the ThreadX library. This project build produces the ThreadX
library file tx.lib.
4. Demonstration System
The ThreadX demonstration is designed to execute on the C6678EVM evaluation board.
Building the demonstration is easy; simply import the "sample_threadx_c6678evm" project.
Now select "Project -> Build Active Project" to build the ThreadX demonstration,
which produces the sample_threadx.out file in the "Debug" directory. You are now
ready to run the ThreadX demonstration on the C6678EVM evaluation board.
Please refer to Chapter 6 of the ThreadX User Guide for a complete description
of this demonstration.
5. System Initialization
The entry point in ThreadX for the TMS320C667x using the TI tools is at label
_c_int00. This is defined within the TI library. In addition, this is
where all static and global pre-set C variable initialization processing
takes place.
The ThreadX initialization file tx_initialize_low_level.asm is responsible
for setting up various system data structures, the vector area, and a periodic
timer interrupt source. By default, the vector area is defined to be located in
the "vectors" section, which is defined at the top of tx_initialize_low_level.asm.
This area is located at address 0 for the demonstration.
tx_initialize_low_level.asm is also where initialization of a periodic timer
interrupt source should take place.
In addition, _tx_initialize_low_level determines the first available address
for use by the application. By default, free memory is assumed to start after
the .zend section in RAM (defined in tx_initialize_low_level). This section
must be placed at the end of your other RAM sections. Please see sample_threadx.cmd
for an example. The address of this section is passed to the application definition
function, tx_application_define.
6. Register Usage and Stack Frames
The TI TMS320C667x compiler assumes that registers A0-A9, A16-A31, B0-B9, and
B16-B31 are scratch registers for each function. All other registers used by
a C function must be preserved by the function. ThreadX takes advantage of this
in situations where a context switch happens as a result of making a ThreadX
service call (which is itself a C function). In such cases, the saved context
of a thread is only the non-scratch registers.
The following defines the saved context stack frames for context switches
that occur as a result of interrupt handling or from thread-level API calls.
All suspended threads have one of these two types of stack frames. The top
of the suspended thread's stack is pointed to by tx_thread_stack_ptr in the
associated thread control block TX_THREAD.

7. Improving Performance
The distribution version of ThreadX is built without any compiler
optimizations. This makes it easy to debug because you can trace or set
breakpoints inside of ThreadX itself. Of course, this costs some performance.
To make it run faster, you can replace the -g compiler option
to a -O3 in the ThreadX project file to enable all compiler optimizations.
In addition, you can eliminate the ThreadX basic API error checking by
compiling your application code with the symbol TX_DISABLE_ERROR_CHECKING
defined.
8. Interrupt Handling
ThreadX provides complete and high-performance interrupt handling for
TMS320C667x targets. There are a certain set of requirements that are
defined in the following sub-sections:
8.1 Vector Area
The TMS320C667x interrupt vectors at in the section "vectors" and is defined at
the top of tx_initialize_low_level.asm. Each interrupt vector entry contains
a jump to a template interrupt processing shell.
8.2 Interrupt Service Routine Shells
The following interrupt processing shells are defined at the bottom of
tx_initialize_low_level.asm:
__tx_int4_ISR
__tx_int5_ISR
__tx_int6_ISR
__tx_int7_ISR
__tx_int8_ISR
__tx_int9_ISR
__tx_int10_ISR
__tx_int11_ISR
__tx_int12_ISR
__tx_int13_ISR
__tx_int14_ISR
__tx_int15_ISR
Each interrupt ISR is entered with B3, A0-A4 is available (these registers are
saved in the initial vector processing). The default interrupt handling
includes calls to __tx_thread_context_save and __tx_thread_context_restore.
Application ISR processing can be added between the context save/restore
calls. Note that only the compiler scratch registers are available for use
after context save return to the ISR.
High-frequency interrupt handlers might not want to perform context
save/restore processing on each interrupt. If this is the case, any
additional registers used must be saved and restored by the ISR and
the interrupt return processing must restore the registers saved by the
initial vector processing. This can be accomplished by adding the
following code to the end of the custom ISR handling:
LDW *+SP(20),A0 ; Recover A0
LDW *+SP(24),A1 ; Recover A1
LDW *+SP(28),A2 ; Recover A2
LDW *+SP(32),A3 ; Recover A3
B IRP ; Return to point of interrupt
|| LDW *+SP(36),A4 ; Recover A4
LDW *+SP(96),B3 ; Recover B3
ADDK.S2 288,SP ; Recover stack space
NOP 3 ; Delay slots
