2) Implement ROR: Suppose the instruction set contained no rotate instructions. Show how you would use SHR and a conditional jump instruction to rotate the contents of the AL register 1 bit to the right.
example: 10000000b in AL becomes 01000000b
10000001b in AL becomes 11000000b
Homework Answers
MOV CL,NUM ;here NUM is no.of positions to rotate
LOOP: SHR AL,1 ;SHR is shift right
JC DOWN1 ;JC - Jump if carry in shift operation, goes to lable
JMP DOWN2 ;JMP -unconditional jump instruction,goes to lable
DOWN1: OR AL, 80H ;OR operation for AL and 80H(10000000)
DOWN2: DEC CL,1 ; DEC - decrement CL with 1
JNZ LOOP ; JNZ - jump of no zero,if it true goes to lable LOOP

Consider a hypothetical computer with an instruction set of only two n-but instructions. The first bit specifies the opcode, and the remaining bits specify one of the 2-1 n-bit words of main memory. The two instructions are as follows: SUBS X: Subtract the contents of location X from the accumulator, and store the result in location X and the accumulator JUMP X: Place address X in Program Counter A word in memory may contain either an instruction or a binary...

Implement the following statements using MS430 assembly instructions. You may use more than one, but you should minimize the number of instructions required. You can use both native and emulated instructions. Use hex notation for all numbers 1. (a) Move the word located in register R14 to R15 (b) Increment the word in R6 by 2. (c) Perform a bitwise ANDing of the word located at address 0x0240 with the datum in R15, placing the results in R15. (d) Rotate...

1.) a.) Using the simplified instruction set shown for part b, write code for the following. Suppose memory locations 1400 to 1449 contain 16-bit words. Each word represents 2 ASCII characters. Write code to read in and write out these 100 characters. Left-side character from location 1400 should be first, right-side character from location 1400 should be second, and remaining characters follow in numeric order. Assume you have access to 4 registers: R1, R2, R3, R4. Each register holds one...

1. The MIPS instruction set includes several shift instructions. They include logical-shift-left (sll), logical-shift-right (srl), and arithmetic-shift-right (sra). [2 +2 4 points] a) Why does not MIPS offer an "arithmetic-shift-left (sla)" instruction? b) Write a MIPS code to implement the logical-shift-left (sll) instruction for a machine that did not have this particular instruction? In other words, you have to write the equivalent of the sll instruction using mul, add and other instructions. Try writing the equivalent of sll Ss1, Ss2,...
