20 | ;; The Geode architecture is one insn issue processor. | |

31 | ;; CPU execution units of the Geode: | |
32 | ;; | |
33 | ;; issue describes the issue pipeline. | |
34 | ;; alu describes the Integer unit | |
35 | ;; fpu describes the FP unit | |
36 | ;; | |
37 | ;; The fp unit is out of order execution unit with register renaming. | |
38 | ;; There is also memory management unit and execution pipeline for | |
39 | ;; load/store operations. We ignore it and difference between insns | |
40 | ;; using memory and registers. | |
