Notes:
1. MB8686X CPI assume Worst Case in 1 command execution.
2. For ASI=0xc, 0xd, 0x10-0x18, 0x31access, the CPI changes.
3. Assumes that delay slots are buried in usable instructions
4. Assumes that all CPI hit to I-cache and d-cache
5. 32bit x 0bit
1cycle
32bit x 8bit
2cycle
32bit x 16bit
3cycle
32bit x 32bit
5cycle
6. Execution of stores in IMB odd clock cycles takes 2 clocks and in even cycles 1 clock.
