What does "ISA" revision mean on the TI compiler Wiki?

Hi All,

What does "ISA" revision mean on this TI compiler Wiki?

  • ISA is instruction set architecture, which means a processor family such as C6000 or MSP.  The family is further subdivided into what are sometimes called revisions.  For MSP, the main division as far as the compiler is concerned is MSP vs. MSPX.  MSP is a strictly 16-bit device, and MSPX supports an 24-bit address space, which means it has extra instructions to access this address space, as well as other improvements.
