Question
Chapter 3.5, Problem 3.8PP
Program Plan Intro
Unary and Binary Operations:
- The details of unary operations includes:
- The single operand serves as both source as well as destination.
- It can either be a register or a memory location.
- The instruction “incq” causes 8 byte element on stack top to be incremented.
- The instruction “decq” causes 8 byte element on stack top to be decremented.
- The details of binary operations includes:
- The first operand denotes the source.
- The second operand serves as both source as well as destination.
- The first operands can whichever be an immediate value, memory location or register.
- The second operands can whichever be a register or a memory location.
Example:
The example for a “subq” instruction is shown below:
subq %rax, %rdx
Here, “%rax” and “%rdx” denotes registers. The given code decrements register “%rdx” by value in “%rax”.

Currently, memory is word-addressed and all memory accesses load or store a 16-bit value. For example, LDA Ox6502 loads a 16-bit value from address Ox6502 into register A. The change is to support additionally 8-bit accesses, thanks to an expanded machine language (already designed by a colleague) which now supports instructions such as: ; load 16 bits from addr 6502 into A ; load 8 bits from addr 6502 into A LDAW Ox6502 LDAB Ox6502 Outline, at a high level, how you would bring about this change in the CPU design, and mentioning any difficulties you expect to encounter.arrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
