This directory contains mpn functions optimized for MIPS3. Example of
|
||||
processors that implement MIPS3 are R4000, R4400, R4600, R4700, and R8000.
|
||||
|
||||
RELEVANT OPTIMIZATION ISSUES
|
||||
|
||||
1. On the R4000 and R4400, branches, both the plain and the "likely" ones,
|
||||
take 3 cycles to execute. (The fastest possible loop will take 4 cycles,
|
||||
because of the delay insn.)
|
||||
|
||||
On the R4600, branches takes a single cycle
|
||||
|
||||
On the R8000, branches often take no noticable cycles, as they are
|
||||
executed in a separate function unit..
|
||||
|
||||
2. The R4000 and R4400 have a load latency of 4 cycles.
|
||||
|
||||
3. On the R4000 and R4400, multiplies take a data-dependent number of
|
||||
cycles, contrary to the SGI documentation. There seem to be 3 or 4
|
||||
possible latencies.
|
||||
|
||||
STATUS
|
||||
|
||||
Good...
