// Notes:

// Instructions are held in the FRACC, LRACC and IRACC pipeline

// - Store instructions will hold in the AGEN stage
|

// - The integer multiply-accumulate instruction will hold in

// the IEXE1 stage
|
|
//
|
|
// For most I-pipe operations, the result is available at the end of

|
// the IEXE1 stage. Operations such as multiply and divide must
|
|
// continue to execute in IEXE2 and IWB. Divide resides in IWB for
|
|
// 33 cycles (multiply also calculates its result in IWB). For all
|
|
// J-pipe instructions, the result is available
|
|
// at the end of the JEXE1 stage. Loads have a 3-cycle latency
|
|
// (data is not available until after the LWB stage).
|
|
//
|
|
// The L1 cache hit latency is four cycles for floating point loads
|
|
// and three cycles for integer loads.
|
|
//
|
|
// The stwcx. instruction requires both the LRACC and the IRACC
|
|
// dispatch stages. It must be issued from DISS0.
|
|
//
|
|
// All lwarx/stwcx. instructions hold in LRACC if another
|
|
// uncommitted lwarx/stwcx. is in AGEN, CRD, or LWB.
|
|
//
|
|
// msync (a.k.a. sync) and mbar will hold in LWB until all load/store
|
|
// resources are empty. AGEN and CRD are held empty until the msync/mbar
|
|
// commits.
|
|
//
|
|
// Most floating-point instructions, computational and move,
|
|
// have a 5-cycle latency. Divide takes longer (30 cycles). Instructions that
|
|
// update the CR take 2 cycles. Stores take 3 cycles and, as mentioned above,
|
|
// loads take 4 cycles (for L1 hit).
