3.8
This section presents V2 processor instruction execution times in terms of processor core clock
cycles. The number of operand references for each instruction is enclosed in parentheses following
the number of processor clock cycles. Each timing entry is presented as C(R/W) where:
This section includes the assumptions concerning the timing values and the execution time details.

For the timing data presented in this section, the following assumptions apply:

Table 3-11. D1 Local Memory Hardware Configuration Information Field Description
• C is the number of processor clock cycles, including all applicable operand fetches and
• R/W is the number of operand reads (R) and writes (W) required by the instruction. An

operation performing a read-modify-write function is denoted as (1/1).
words at the beginning of each instruction execution. This implies that the OEP does not
wait for the instruction fetch pipeline (IFP) to supply opwords and/or extension words.
processors, the most common example of this type of stall involves consecutive store
operations, excluding the MOVEM instruction. For all STORE operations (except
MOVEM), certain hardware resources within the processor are marked as “busy” for two
processor clock cycles after the final DSOC cycle of the store instruction. If a subsequent
STORE instruction is encountered within this 2-cycle window, it will be stalled until the
resource again becomes available. Thus, the maximum pipeline stall involving
consecutive STORE operations is 2 cycles. The MOVEM instruction uses a different set
of resources and this stall does not apply.
