References

Every statement in this wiki is cross-checked against the original Texas Instruments documents below. These are the normative sources; where this wiki and a manual disagree, the manual is correct and the wiki should be fixed.

Primary

TI number	Title	Year	Used for
SPRU056D	TMS320C5x User's Guide	1998	Architecture, CPU, registers, program control, addressing modes, the instruction set (chapter 6), pipeline, memory, peripherals.
SPRU018D	TMS320C1x/C2x/C2xx/C5x Assembly Language Tools User's Guide	1995	Assembler source syntax, directives, macro language, instruction-set summary, archiver, linker command language, hex-conversion utility, and COFF. The byte-level COFF layout (file, section, symbol and relocation structures) is in Appendix A, with the relocation types in Table A-9; this is what `lib/c5xcoff/` implements.

Supporting

TI number	Title	Year	Used for
SPRS030A	TMS320C5x / LC5x Fixed-Point DSP Data Sheet	1996	Electrical and timing facts, device variants, pinout-level detail.
SPRZ113A	TMS320C5x User's Guide Errata / Update	1998	Corrections applied on top of SPRU056D.
SPRU055B	TMS320C5x C Source Debugger User's Guide	1998	Debugger behaviour (context only; not required for the toolchain).

Getting the documents

All five are public Texas Instruments PDFs:

SPRU018D: https://www.ti.com/lit/ug/spru018d/spru018d.pdf

Offline copies of the two primary manuals and the SPRZ113A errata are kept in the repository under docs/.

Notes on terminology

"The reference assembler / linker / hex utility" in the tool documentation means the TI tools described in SPRU018D (dspa, dsplnk, dsphex).
Register and instruction names are spelled as in SPRU056D.
Instruction encodings are additionally checked against the toolchain's own instruction table (include/c5x_isa.h), which is itself derived from SPRU056D chapter 6.
