Assume a typical program has the following instruction type breakdown: Instruction Type Instruction percent Instruction Latencies Load 35 % 4 cycles Stores 10 % 4 cycles Adds 50 % 2 cycles Multiplies 3 % 16 cycles Divides 2 % 50 cycles If for the next-generation design you could pick one type of instruction to make twice as fast (half the latency), which instruction type would you pick? O a. Multiply O b. Store O C. Load O d. Add How many check bits are needed if the Hamming error correction code is used to detect single bit errors in a 1024-bit data word? O a. 12 O b. 10 O c. 11 O d. 15
