Chip support library
From Texas Instruments Embedded Processors Wiki

Texas Instruments Chip Support Libraries (CSL) provide an application programming interface (API) used for configuring and controlling the DSP on-chip peripherals for ease of use, compatibility between various devices and hardware abstraction. This will shorten development time by providing standardization and portability.
Sometimes referred to as part of DSP Foundation Software for TMS320C6000™ and TMS320C5000™ DSPs, this collection of functions, macros and symbols is a fully scalable component of the DSP/BIOS kernel within Code Composer Studio IDE. CSL provides C-program functions to help you quickly and easily program your on-chip peripherals.

Chip Support Library for C6000
The Chip Support Library (CSL) provides an application programming interface (API) used for configuring and controlling the DSP on-chip peripherals for ease of use, compatibility between various C6000 devices and hardware abstraction. The functions listed in the features section are specifically designed for the following devices: C6201, C6202, C6203, C6204, C6205, C6211, C6410, C6412, C6413, C6414, C6415, C6416, C6418, C6701, C6711, C6712, C6713, DA610, DM640, DM641, and DM642.

Chip Support Library for C6455
This release of CSL for TMS320C6455 contains peripheral programming (functional and register level) APIs for C6455 modules. This set of APIs provides peripheral abstraction that can be used by higher layers of software.To download, please click here.
Chip Support Library for C6457
This release of CSL for TMS320C6457 contains peripheral programming (functional and register level) APIs for C6457 modules. This set of APIs provides peripheral abstraction that can be used by higher layers of software.To download, please click here.
Chip Support Library for C6424
The C6424 EVM does not have a specific CSL (Chip Support Library); instead it has a PSP (Platform Support Package) that provides drivers for the peripherals in addition to a register layer CSL. You can find the software in the CD accompanying the evaluation board. In addition, the release of PSP for C6424 CSL is available.To download, please click here.
This PSP package contains DSP/BIOS drivers and CSL (register layer) for DM648, C6452, DM6437 and C6424 SoCs.
Chip Support Library for C5000
To download the CSL (Chip Support Library) for C5000, please click here.
The functions listed in the features section are specifically designed for all the C55xx DSPs including C5502, C5509, C5509A, and C5510 (PG 1.2 and 2.0). The C5506 is also supported, but you must use C5509A settings.
Chip Support Library for C2000
C2000 does not have a CSL but the C28x family is supported by a set of C/C++ Header Files and Peripheral Examples for the C28x family.
The DSP28xx C/C++ peripheral header files and example projects files facilitate writing C/C++ Code for the TI’s 28xx DSCs. The code can be used as a learning tool or as the basis for a development platform depending on the current needs of the user.

FAQ's
Q: where is the C6457 CSL API documentation?
the API reference guide is not included as it can be dynamically generated via doxygen
- download and install the utility
- (optional) install graphwiz if you want to have visual call tree documentation included
- run doxygen and open the file (file > open) 'doxyfile', it will pre-load the settings for you
- check / modify the directory installation for the source and the destination folder as they need to be changed for your machine (in the 'project' topic of the wizard panel)
- (optional) select "use dot tool from the GraphWiz package" within the diagrams tab of the doxygen wizard to enable the graphs
- then go to the run tab and hit 'run doxygen' button
It will create within the output directory you specified an html folder, and within this, the index.html file which you would open within your browser to access the documentation
Q: Can CSL be used without DSP/BIOS?
Yes. The Chip Support Library(CSL) is a library with a set of API calls which can be used independant of DSP/BIOS. The document titled Chip Support Library API Reference Guide (SPRU420 for C54x, SPRU433 for C55x, SPRU401 for C6x) contains a section describing the method of including the CSL libraries without using the DSP/BIOS interface.
Q: Is it possible to modify CSL source and header files?
The CCS installation includes a CSL component that can be located in the /.../bios/lib and /.../bios/include.
The CSL component consists of:
- A set of CSL libraries in the bios/lib folder
- The archived CSL sources and headers in the bios/lib folder
- A set of CSL header files in the bios/include folder
The archived sources (csl54xx.src, csl55xx.src or csl6000.src) are created with the archiver found in the /.../cgtools directory. These can be unarchived using the same utility and the sources and headers can be modified. These modified sources and headers can then be built to create a custom library. Be sure to use the modified headers with the new library, as the changes will not be reflected in the originally installed CSL headers.
