Memory operand - Study guides, Class notes & Summaries

OP code The portion (bit field) of a machine language instruction that specifies the operation to be done by the CPU. Control Transfer Instruction A type of instruction that modifies the machine's program counter (other than by simply incrementing it). Indexed Addressing A way of specifying the location of an operand in memory by adding a constant embedded in the instruction to the contents of a "pointer" register inside the CPU. Zero-Operand Instruction These would b...

MIPS Test Questions with All Correct Answers Which one of the following address are half-word aligned? A. 0x01004F35 B. 0x01004F37 C. 0x01004F3A D. 0x01004F3F - Answer-C. 0x01004F3A Say that data is in memory and the base register has been initialized correctly. You have the following program: lh $5,0($10) lb $6,4($10) addu $7,$5,$4 What does the addu instruction do? A. It performs the binary addition algorithm on whatever 32-bit patterns are in registers $4 and $5. B....

The ALU component of the CPU moves data and instructions between main memory and registers. True or false Ans: F A complex chain of events occurs when the CPU executes a program. True or False Ans: T The CPU alternates constantly between fetch and execution cycles. True or False Ans: T The operand of a CPU instruction cannot contain the location of a data item. True or False Ans: F Data inputs are accessed from storage or extracted directly from the operands and stored in one or ...
