9 // This file defines the resources required by P9 instructions. This is part of
10 // the P9 processor model used for instruction scheduling. This file should
11 // contain all the instructions that may be used on Power 9. This is not
12 // just instructions that are new on Power 9 but also instructions that were
13 // available on earlier architectures and are still used in Power 9.
15 // The makeup of the P9 CPU is modeled as follows:
16 // - Each CPU is made up of two superslices.
17 // - Each superslice is made up of two slices. Therefore, there are 4 slices
19 // - Up to 6 instructions can be dispatched to each CPU. Three per superslice.
21 // - One CY (Crypto) unit P9_CY_*
22 // - One DFU (Decimal Floating Point and Quad Precision) unit P9_DFU_*
23 // - Two PM (Permute) units. One on each superslice. P9_PM_*
24 // - Two DIV (Fixed Point Divide) units. One on each superslize. P9_DIV_*
25 // - Four ALU (Fixed Point Arithmetic) units. One on each slice. P9_ALU_*
26 // - Four DP (Floating Point) units. One on each slice. P9_DP_*
27 // This also includes fixed point multiply add.
28 // - Four AGEN (Address Generation) units. One for each slice. P9_AGEN_*
29 // - Four Load/Store Queues. P9_LS_*
30 // - Each set of instructions will require a number of these resources.
31 //===----------------------------------------------------------------------===//
33 // Two cycle ALU vector operation that uses an entire superslice.
34 // Uses both ALU units (the even ALUE and odd ALUO units), two pipelines
35 // (EXECE, EXECO) and 1 dispatch (DISP) to the given superslice.
