Study Notes
Accumulator Architecture
- The accumulator is both an implicit input operand and a result.
Stack Architecture
- Requires separate instructions like
pushorpopto transfer operands between memory and registers.
Register-Memory Architecture
- Features instructions that operate on one operand in a register and another operand in memory.
Accumulator Architecture
- Supports single operand instructions with an implicit accumulator.
Register Architecture
- All operands are registers, and transfer to memory requires separate load or store instructions.
Operation Code Field
- Specifies the operation to be performed in a computer instruction.
Mode Field
- Specifies how to access operands in a computer instruction.
Memory-Register Architecture
- One input operand is in memory, and the other is in a register.
Load-Store Architecture
- Memory access is only through load and store instructions.

Description
Test your knowledge of MIPS (Microprocessor without Interlocked Pipeline Stages) processor architecture with questions about immediate, register direct, indirect, displacement, indexed, and memory indirect addressing modes. Learn about the different operations like RR+3, RR+R, RR+M, RR+M[R], RR+M[100+R], RR+M[R+R], and RR+M[M[R]].
