TMS320C28x Instruction Set Architecture

TMS implementation in SimNML for the GLISS2 ISS generator. TMS320C28x CPU and Instruction Set Reference Guide, TMS320C28x Floating Point Unit and Instruction Set, and TMS320C28x Extended Instruction Sets Technical Reference Manual (from ti.com).

This GLISS ISA supports TMS320C28x, 32-bits architecture, with both 16-bit and 32-bit instructions.

You must use our fork of GLISS2 for some critical fixes.

Installation

GLISS2 must be available as a sibling directory:

cd ..
hg clone https://wwwwsecu.irit.fr/hg/TRACES/gliss2/trunk gliss2
cd gliss2
make
cd ../tms

Then, you have just to build ISS, disassembler and libraries with:

make WITH_DYNLIB=

or

make

to enable -fPIC.

Disassembler Use

You can find the disassembler in disasm/tms-disasm and run it as such

disasm/tms-disasm <binaryfile>.elf

There is only one mode, tms, so you don't need to specify -m. You can test this repository with

make test_disasm
