The SW IPC values shown assume a latency of 1 clock cycle for instruction fetch, which is not the case for the DDR-PLB architecture, but is valid for LMB-based architectures.
This maximum was computed assuming a software instruction fetch latency of 1 clock cycle (implying IPC = 1), which does not hold true for the DDR case.
There are four stages used in this processor, for example, instruction fetch, decode, execute, and write back stages.
The latency can be utilized to cover the timing intervals of one instruction fetch stage with decode/execute/writeback/donothing stages of previous instructions, for example, instructions I2 and I3 in Figure 11.
Note the "combined" miss rate is the fraction of instruction fetches which suffer misses in both the 32KB I-cache and the 1MB L2 cache.
Following instruction fetch and decode, register renaming is performed, as in the base processor.
These results, however, fall short of peak processor throughput (the 8 instructions per cycle limit imposed by instruction fetch and decode bandwidth), in part because they encompass the execution of the entire program, including the sequential parts of the code.
A Macro instruction actually represents a branch into the ROM; the instruction fetch unit starts fetching instructions from the ROM at the address specified by the macro opcode.
The Op code fetched from the internal ROM in state 2 is examined in state 3 and depending upon which instruction is being fetched, the control goes to other states to execute the Instruction fetched. If the pc address is greater than 4K bytes, then the control goes to state 5 indicating that the Op code is to be fetched from external ROM.
