- Hi. I'm working on a project where we need to analyze pixstats
- output run on the MIPS R3000 architecture. There are a number of
- opcodes in the output for which we cannot seem to find definitions.
- (We've looked in the "MIPS RISC Architecture" by Gerry Kane). I
- would appreciate it GREATLY if anyone could explain what these
- MEAN, and/or where I might be able to find them:
-
- 1. cop1
- 2. spec - in particular, what do these include? (We have a separate
- output for syscall, which are supposedly a part of these.)
- 3. fadd, fmul - are these floating point operations?
- if so, are they double precision or single
- precision?
- 4. bcond - if these are conditional branches, why are they separate
- from all the other specific cond. branches (e.g., beq,
- etc.)?
- 5. bff, cff - for these and the following, we really have no clue
- 6. ctf, mtf
- 7. c.lt, c.olt
- 8. fcvtd, fcvtw
- 9. b
- 10. bcond - if these are conditional branches, why are they separate
- from all the other specific cond. branches (e.g., beq,
- etc.)?
-
- If you have ANY info. on any of the above, please mail responses to:

- Thanks!
