| 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. |
---|
| 61 | ; fixed a few typos in comments. |

---|
| 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. |

---|
| 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. |
