The Z83 C Compiler is an optimizing cross compiler for a language very similar to C targeted toward the TI83+. The output from the compiler may be assembled with TASM (http://home.comcast.net/~tasm/) or ZASM (http://lpg.ticalc.org/prj_zasm/).
Binutils, gcc, gdb and glibc re-targeted for MIPS R3000R and R5900 as shipped in PlayStation and PlayStation 2 video game consoles, both from Sony Computer Entertainment Inc.
