Consider the following program in MA dE assembly language. a) Complete the table detailing the RTN for next 2 instructions only that will be executed including the content of registers PC, IR, MAR, MBR and AC in hexadecimal. Note the first instruction LOAD X is already filled. Note also that SKIPCOND instruction has no operands, therefore you can complete Fetch, decode and execute cycles only. b) Explain in one statement the task performed by this program? / AC = X if AC > 0 then PC = PC + 1 (skip) LOAD X Repeat, SKIPCOND 800 / Go to End / AC JUMP End SUBT One AC
