// This file defines the resources required by P9 instructions. This is part
|
|
// P9 processor model used for instruction scheduling. This file should contain
|
|
// all of the instructions that may be used on Power 9. This is not just
|
|
// instructions that are new on Power 9 but also instructions that were
|
|
// available on earlier architectures and are still used in Power 9.
|
|
//
|
|
// The makeup of the P9 CPU is modeled as follows:
|
|
// - Each CPU is made up of two superslices.
|
|
// - Each superslice is made up of two slices. Therefore, there are 4 slices
|
|
// for each CPU.
|
|
// - Up to 6 instructions can be dispatched to each CPU. Three per superslice.
|
|
// - Each CPU has:
|
|
// - One CY (Crypto) unit P9_CY_*
|
|
// - One DFU (Decimal Floating Point and Quad Precision) unit P9_DFU_*
|
|
// - Two PM (Permute) units. One on each superslice. P9_PM_*
|
|
// - Two DIV (Fixed Point Divide) units. One on each superslize. P9_DIV_*
|
|
// - Four ALU (Fixed Point Arithmetic) units. One on each slice. P9_ALU_*
|
|
// - Four DP (Floating Point) units. One on each slice. P9_DP_*
|
|
// This also includes fixed point multiply add.
|
|
// - Four AGEN (Address Generation) units. One for each slice. P9_AGEN_*
|
|
// - Four Load/Store Queues. P9_LS_*
|
|
// - Each set of instructions will require a number of these resources.

// Uses both ALU units (the even ALUE and odd ALUO units), two pipelines
