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. 15 O c. 11 O d. 10 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? a. Store b. Add c. Load d. Multiply
