EE 3750 — HW 2 solutions 1 EE 3750 — Homework 2 solutions Fall 2002 1. Let AX = 19C3H, BX = 2B11H, CX = 3EE0H, and SP = 1988H. What are the contents of AX, BX, CX, and SP after the following sequence of instructions? PUSH BX POP AX PUSH AX PUSH CX POP BX AX = 2B11H, BX = 3EE0H, CX = 3EE0H, and SP = 1986H. 2. The following equation arises in calculating flow conditions for natural gas through a pipe. H = Q C 2 P + A (a) Write an 8086 instruction sequence to compute the equation assuming that the values are given as unsigned binary integers. Let Q be a word variable, and let C , P , and A be byte variables. What type of variable should H be? (b) Write an 8086 instruction sequence to compute the equation assuming that the values are given in unpacked BCD format. All variables are byte variables. Variable Q is a two digit value, while C , P , and A are one digit values. Additional simplifications: Part (a) - To simplify the problem, ignore the remainders of both divisions, and assume that the sum of P+A fits into one byte. Part (b) - To simplify the problem, assume that the quotient of Q/C is one digit long,
