Computer architecture.

 With a MIPS pipeline architecture, we can have four different branch alternatives as follows. Assume we have a 500MHz machine for which the following measurements have been made and the CPI of instruction except branch is 1. What are the MIPS rates for each scheme?

Assume 4% unconditional branch, 6% conditional branch- untaken, 10% conditional branch-taken.
