// Functional units on the PowerPC 440/450 chip sets
//
def IFTH1 : FuncUnit; // Fetch unit 1
def IFTH2 : FuncUnit; // Fetch unit 2
def PDCD1 : FuncUnit; // Decode unit 1
def PDCD2 : FuncUnit; // Decode unit 2
def DISS1 : FuncUnit; // Issue unit 1
def DISS2 : FuncUnit; // Issue unit 2
def LRACC : FuncUnit; // Register access and dispatch for
// the simple integer (J-pipe) and
// load/store (L-pipe) pipelines
def IRACC : FuncUnit; // Register access and dispatch for
// the complex integer (I-pipe) pipeline
def FRACC : FuncUnit; // Register access and dispatch for
// the floating-point execution (F-pipe) pipeline
def IEXE1 : FuncUnit; // Execution stage 1 for the I pipeline
def IEXE2 : FuncUnit; // Execution stage 2 for the I pipeline
def IWB : FuncUnit; // Write-back unit for the I pipeline
def JEXE1 : FuncUnit; // Execution stage 1 for the J pipeline
def JEXE2 : FuncUnit; // Execution stage 2 for the J pipeline
def JWB : FuncUnit; // Write-back unit for the J pipeline
def AGEN : FuncUnit; // Address generation for the L pipeline
def CRD : FuncUnit; // D-cache access for the L pipeline
def LWB : FuncUnit; // Write-back unit for the L pipeline
def FEXE1 : FuncUnit; // Execution stage 1 for the F pipeline
def FEXE2 : FuncUnit; // Execution stage 2 for the F pipeline
def FEXE3 : FuncUnit; // Execution stage 3 for the F pipeline
def FEXE4 : FuncUnit; // Execution stage 4 for the F pipeline
def FEXE5 : FuncUnit; // Execution stage 5 for the F pipeline
def FEXE6 : FuncUnit; // Execution stage 6 for the F pipeline
def FWB : FuncUnit; // Write-back unit for the F pipeline
def LWARX_Hold : FuncUnit; // This is a pseudo-unit which is used
// to make sure that no lwarx/stwcx.
// instructions are issued while another
// lwarx/stwcx. is in the L pipe.
def GPR_Bypass : Bypass; // The bypass for general-purpose regs.
def FPR_Bypass : Bypass; // The bypass for floating-point regs.
// Notes:
// Instructions are held in the FRACC, LRACC and IRACC pipeline
// stages until their source operands become ready. Exceptions:
// - 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).
//
// This file defines the itinerary class data for the PPC 440 processor.
