| def P440_LRACC : FuncUnit; // Register access and dispatch for |
| // the simple integer (J-pipe) and |
| // load/store (L-pipe) pipelines |
| def P440_IRACC : FuncUnit; // Register access and dispatch for |
| // the complex integer (I-pipe) pipeline |

| def P440_FEXE6 : FuncUnit; // Execution stage 6 for the F pipeline |
| def P440_FWB : FuncUnit; // Write-back unit for the F pipeline |
| |
| def P440_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 P440_GPR_Bypass : Bypass; // The bypass for general-purpose regs. |
| def P440_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). |
| |
