- If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?arrow_forwardProvide the format and assembly language instruction for the following hex values: Address 1000: 13 Address 1001: 03 Address 1002: C5 Address 1003: 00 First consider big-endian vs. little-endian as you convert to binary. Then, divide the bits up into the appropriate fields, decipher the opcode, and so on.arrow_forwardin 80886 microprocessor Suppose that.
