Reorder buffer can be operand source. Ryan Taylor. Xiaoming. Li. Motivation. To understand behavior of major kernel characteristics. ALU:Fetch. Ratio. Read Latency. Write Latency. Register Usage. Domain Size. Cache Effect. Use micro-benchmarks as guidelines for general optimizations. One instruction can be fetched at each cycle.. Latency is 2 cycles for ALU, and 3 for multiplier. Instructions begin execution once fetched. In case two instructions finish at the same cycle, both can commit on the same cycle and the CDB arbitrates who writes first. Microarchitecture. Lecture 3: Superscalar . Fetch. Fetch Rate is an ILP Upper Bound. To sustain an execution rate of N IPC, you must be able to sustain a fetch rate of N IPC!. Over the long term, you cannot burn 2000 calories a day while only consuming 1500 calories a day. You will starve!. Exploiting More ILP. Branch prediction reduces stalls but may not be sufficient to generate the desired amount of ILP. One way to overcome control dependencies is with . speculation. Make a guess and execute program as if our guess is correct. Spring 2014. Lecture . 8. : Advanced Out. -of-Order Superscalar . Designs Part-II.
