(b) [3%] What is the MIPS rating for?
#445007
(c) [3%] A favorite program runs in 10 seconds on machine M1. If we want to build a new machine M3, which will run this program in 6 seconds. But it require 1.2 times as many clock cycles as M1 for this program. What is the clock rate of M3?
#445008
(a) [3%] Assume 185 and 169 are signed 8-bit decimal integers store in sign-magnitude format. Calculate 185+169. The result should be written in decimal.
#445009
(b) [3%] Assume 185 and 169 are signed 8-bit decimal integers store in two's complement format. Calculate 185+169. The result should be written in decimal.
#445010
(d) [4%] Calculate the binary number (1.1100)*(-0.1101) step by step. You should use guard, round and sticky bit in rounding step. The result should store in IEEE 754 with 5 bits mantissa.
