7.2.2 Coprocessor Conditional Instructions
The conditional instruction category provides program control based on the operations of
the coprocessor. The coprocessor evaluates a condition and returns a true/false indicator
to the main processor. The main processor completes the execution of the instruction
based on this true/false condition indicator.
The implementation of instructions in the conditional category promotes efficient use of
both the main processor and the coprocessor hardware. The condition specified for the
instruction is related to the coprocessor operation and is therefore evaluated by the
coprocessor. However, the instruction completion following the condition evaluation is
directly related to the operation of the main processor. The main processor performs the
change of flow, the setting of a byte, or the TRAP operation, since its architecture explicitly
implements these operations for its instruction set.
Figure 7-8 shows the protocol for a conditional category coprocessor instruction. The main
processor initiates execution of an instruction in this category by writing a condition
selector to the condition CIR. The coprocessor decodes the condition selector to
determine the condition to evaluate. The coprocessor can use response primitives to
request that the main processor provide services required for the condition evaluation.
