Question

Write a program to implement the following function: y = |x| The 32-bit signed variable x is stored at memory location labeled with x, the variable y is to be stored at memory location labeled with y. Code the following IF-THEN statement using ARM instructions If(r2! = r7) r2 = r2 - r7 else r2 = r2+4 Translate the following conditions into a single ARM instruction: a. Add register r3 and r6 only if N is clear. Store result in register r7 b. Multiply register r7 and r12, putting the results in register r3 only if C is set and Z is clear. c. Compare registers r6 and r8 only if Z is clear. prove that for the GT condition, the flag setting should be N = V & Z = 0 Write an assembly program that calculates the following function. Assume the signed integer input x is stored in register r0 and the result f(x) is saved in register r1. f(x) = {-1 if x 0 prove that for the lessthanorequalto condition, the flag setting should N! = V or Z = 1

Explanation / Answer

module modulus (x,y);

input x[31:0];

output y[31:0];

assign y[31] = x[31] | (~x[31]);

assign y[30:0] = x[30:0];

endmodule
