This question assumes the machine architecture at the right. Note the stack pointer register, SP, is not part of the register file. SEL is a multiplexor used to select one of the inputs to the ALU. Assume memory addresses require only one memory cycle to fetch or store (unlike the 68000). MAR Register File (RO-RI5) MDR Show the machine code control IR constnts Y sequence of an instruction that will set a block of from 1 to 127 memory locations to zero. The size of the block is in RO and the address of the block is in R1. Assume SEL PC SP ALU TEMP Status the instruction fetch sequence is the same as in Question 4 and start with the next step. R0 and R1 can change in the execution of the sequence.
