40 | ; Date: March 31, 1989 |
---|
41 | ; Author: Roy Carlson per Bob Perlman and Richard Relph |
---|
42 | ; |
---|
43 | ; The symbols section describing transactions was modified to contain |
---|
44 | ; several new symbol values. The reason for the change was to force the |
---|
45 | ; CA bit to be set--and remain set--once code accesses the coprocessor. |
---|
46 | ; |
---|
47 | ; Future operating systems will use the Coprocessor Active (CA) bit in |
---|
48 | ; the Old Processor Status Register to determine whether or not to save |
---|
49 | ; coprocessor state, etc.. This means that the instruction control field |
---|
50 | ; Set Coprocessor Active (SA) bit should be used as follows: |
---|
51 | ; |
---|
52 | ; (1) any coprocessor STORE must have its SA bit set to 1, |
---|
53 | ; so as to set CA, |
---|
54 | ; |
---|
55 | ; and (2) any coprocessor LOAD must have its SA bit set to 0, |
---|
56 | ; so as to prevent clearing CA. |

59 | ; Corrected CP_IEEE_GRADUAL_UFLOW_MODE and CP_RMS_MASK. |
---|
60 | ; Added CP_EXCPS_POSITION, the ls bit of the CP_XXX_EXCP ensemble. |

67 | ; 1) The _cp_prec_field in the "cp_build_inst", "cp_build_inst_h" |
---|
68 | ; and "cp_build_inst_l" macros was not being defined in the case |
---|
69 | ; of Am29K-supported floating-point instructions (e.g., FADD, FSUB, |
---|
70 | ; DADD, etc.). |
---|
71 | ; |
---|
72 | ; 2) The multiplexor select codes in the opcode table entries |
---|
73 | ; associated with the "cp_build_inst", "cp_build_inst_h" and |
---|
74 | ; "cp_build_inst_l" macros, pertaining to the CONVERT_F_TO_D |
---|
75 | ; and CONVERT_D_TO_F instructions were incorrect. |

---|
2390 | ; FUNCTION: Builds a 16 MSBs of a 32-bit Am29027 instruction in an |
---|
2391 | ; Am29000 g.p. register. |
---|
2392 | ; |
---|
2393 | ; PARAMETERS: |
---|
2394 | ; reg - the Am29000 g.p. register into which the instruction word |
---|
2395 | ; is to be written |
---|
2396 | ; |
---|
2397 | ; op_code - mnemonic specifying the operation to be performed |
---|
2398 | ; (e.g. FADD, P_TIMES_Q) |
---|
2399 | ; |
---|
2400 | ; precision - precision specification for destination, source operands: |
---|
2401 | ; D_S - double-prec. result, single-prec. input(s) |
---|
2402 | ; D_D - double-prec. result, double-prec. input(s) |
---|
2403 | ; S_S - single-prec. result, single-prec. input(s) |
---|
2404 | ; S_D - single-prec. result, double-prec. input(s) |
---|
2405 | ; |
---|
2406 | ; dest - destination for the operation result: |
---|
2407 | ; RF0 - store result in Am29027 register file location RF0 |
---|
2408 | ; RF1 - store result in Am29027 register file location RF1 |
---|
2409 | ; RF2 - store result in Am29027 register file location RF2 |

---|
2414 | ; RF7 - store result in Am29027 register file location RF7 |
---|
2415 | ; GP - result is to be stored in an Am29000 g.p. register |
---|
2416 | ; with a read_dp, read_sp, or read_int macro. |
---|
2417 | ; |
---|
2418 | ; source1, |
---|
2419 | ; source2, |

---|
2430 | ; RF7 - take source from Am29027 register file location RF7 |
---|
2431 | ; 0 - source is 0 |
---|
2432 | ; ONE_HALF - source is constant .5 (f.p. operations only) |
---|
2433 | ; IMINUS1 - source is constant -1 (integer operations only) |

2443 | ; cp_build_inst_h reg,op_code,[precision,]dest,source1[,source2][,source3] |
---|
2444 | ; |
---|
2445 | ; This macro is similar to cp_build_inst, but creates only the 16 MSBs |
---|
2446 | ; of the 32-bit Am29027 instruction word. This macro is useful in cases |
---|
2447 | ; where the 16 LSBs of instruction word, which specify the operation |
---|
2448 | ; to be performed, already exist in an Am29000 g.p. register, but where |
---|
2449 | ; the 16 MSBs, which specify operand sources and destination, must be |
---|
2450 | ; changed. In such cases, one Am29000 instruction can be saved by using |
---|
2451 | ; cp_build_inst_h instead of cp_build_inst. |
---|
2452 | ; |
---|
2453 | ; Syntax and usage are identical to that of cp_build_inst. |
---|
2454 | ; |
---|
2455 | ; NOTE: This macro references macro _cp_set_op_params, which appears |

2456 | ; in the assembly listing for macro _cp_build_inst. |

---|
2687 | ; FUNCTION: Builds a 16 LSBs of a 32-bit Am29027 instruction in an |
---|
2688 | ; Am29000 g.p. register; the 16 MSBs of the register are |
---|
2689 | ; set to 0.. |
---|
2690 | ; |
---|
2691 | ; PARAMETERS: |
---|
2692 | ; reg - the Am29000 g.p. register into which the instruction word |
---|
2693 | ; is to be written |
---|
2694 | ; |
---|
2695 | ; op_code - mnemonic specifying the operation to be performed |
---|
2696 | ; (e.g. FADD, P_TIMES_Q) |
---|
2697 | ; |
---|
2698 | ; precision - precision specification for destination, source operands: |
---|
2699 | ; D_S - double-prec. result, single-prec. input(s) |
---|
2700 | ; D_D - double-prec. result, double-prec. input(s) |

2702 | ; S_D - single-prec. result, double-prec. input(s) |
---|
2703 | ; |
---|
2704 | ; dest - destination for the operation result: |
---|
2705 | ; RF0 - store result in Am29027 register file location RF0 |
---|
2706 | ; RF1 - store result in Am29027 register file location RF1 |
---|
2707 | ; RF2 - store result in Am29027 register file location RF2 |
---|
2708 | ; RF3 - store result in Am29027 register file location RF3 |
---|
2709 | ; RF4 - store result in Am29027 register file location RF4 |

---|
2711 | ; RF6 - store result in Am29027 register file location RF6 |
---|
2712 | ; RF7 - store result in Am29027 register file location RF7 |
---|
2713 | ; GP - result is to be stored in an Am29000 g.p. register |
---|
2714 | ; with a read_dp, read_sp, or read_int macro. |
---|
2715 | ; |
---|
2716 | ; source1, |
---|
2717 | ; source2, |

2727 | ; RF6 - take source from Am29027 register file location RF6 |
---|
2728 | ; RF7 - take source from Am29027 register file location RF7 |
---|
2729 | ; 0 - source is 0 |
---|
2730 | ; ONE_HALF - source is constant .5 (f.p. operations only) |
---|
2731 | ; IMINUS1 - source is constant -1 (integer operations only) |
---|
2732 | ; 1 - source is constant 1 |
---|
2733 | ; 2 - source is constant 2 |

---|
2742 | ; |
---|
2743 | ; This macro is similar to cp_build_inst, but creates only the 16 LSBs |
---|
2744 | ; of the 32-bit Am29027 instruction word; the 16 MSBs of the target |
---|
2745 | ; register are set to 0. This macro is useful in cases |
---|
2746 | ; where it is helpful to specify instruction LSBs and MSBs separately, |
---|
2747 | ; to improve instruction scheduling. |
---|
2748 | ; |
---|
2749 | ; Syntax and usage are identical to that of cp_build_inst. |

2752 | ; in the assembly listing for macro _cp_build_inst. |
