The 80 x 86 instruction MOVAX, 0123 will _______________.
Group of answer choices
subtract the value 0123 Hex from AX
move the value 0123 Hex to AX
move AX to memory location 0123 Hex
add the value 0123 Hex to AX
Homework Answers
The provided instruction MOV AX, 0123:
Answer: move the value 0123 Hex to AX register.
Description:
•The provided instruction MOV AX, 0123 will move the value 0123H to AX register.
• So, AH register will have 01H and AL register will have 23H.

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...

The AVR provides a rich instruction set to support high-level languages. The AVR address- ing modes also simplify the access of complex data structures. The AVR has a version of the ADD instruction that includes the C flag as one of the source operands, which enables multiple- precision addition operation. The AVR also has a version of the SUB instruction that includes the C flag as one of source operands and hence is used to perform multiprecision subtraction operation. The...

Objective: Add the hexadecimal value 0A3F from a memory location to the hexadecimal value 0FF2 in a register and store the result in the memory. Subtract one from the result, then move the result to both another register and another memory location. 1. Draw a flowchart to break down the steps and storage locations for this program.

A microprocessor has a decrement memory direct instruction, which subtracts 1 from the value in a memory location. The instruction has five stages: fetch opcode (two bus clock cycles), fetch operand address (five cycles), fetch operand (five cycles), subtract 1 from operand (four cycles), and store operand (two cycles). a. By what amount (in percent) will the duration of the instruction increase if we have to insert one bus wait state in each memory read and memory write operation? b....
