## Summary
|
|
|
|
* the difficult arrays are the 2r4w (gpr, fpr, rv) and the cams; everything else is 1r1w
|
|
|
|
* cpl array is 1r1w (written in iu6, read in cp0), arranged even/odd for i0/i1; CPL_Q_DEPTH=32 means 32 even + 32 odd(?)
|
|
|
|
* some of these are directly changed with gen parameters; others may be do-able with some combo or parameters/spr settings/simple logic changes
|
|
|
|
* GPR rename pool size
|
|
* FPR rename pool size
|
|
* completion queue depth
|
|
* IERAT size
|
|
* IC size
|
|
* IC ways
|
|
* BTB size
|
|
* BHT size
|
|
* DERAT size
|
|
* DC size
|
|
* DC ways
|
|
* TLB size
|
|
* TLB ways
|
|
|
|
* e.g. no xlate, small caches
|
|
|
|
* IERAT, DERAT replaced with single-entry always-hit (no CAMs)
|
|
* IC, DC 1W small data
|
|
* no TLB
|
|
* alter BTB, BHT, rename, completion as necessary
|
|
* mmu logic (and fpu if not needed) could be dropped
