Answer #1

Suppose you are to encode a two-address instruction with 8 bits. The opcode part of the instruction is 2 bits. Each address takes the same number of bits within the operand, how many bits should be allocated for each address in the operand? 7. b)2 3 e) 6 d) 5 Because, from 8 bit 2 bits for opcode rest 6 bits for two address each with same number of both. So each address gets 3 bits 8. Which of the following are valid commands in YASM? a) pop (b)mov c) while d) cmp e) if Because, while,cmp,if are not YASM commands. Which of the following are sections that make up a YASM program? 9. a) system@sata (c)bss Id)preprocessor directive (e)text Because, except system above all sections are used to switch execution from one to another 10. The Boolean statement: (A + B)(A + CIA + D), is equal to 1 when? (d)BCD-1 eahich eakac in an unsigned 32 bit integer A, and A#1 b) AB-1 c)B-C-D e) never Because, (A+B)(A+C)(A+D) each sum has a term A, when A is 1 then its1 Similarly, after implying we have some sum of product terms, BCD is one of them, So when BCD is 1, the expression is 1
