3.2 MIPS Architecture and Instruction Set
The MIPS (MIPS Instruction Set) architecture is a RISC (Reduced Instruction Set Computing) architecture known for its simplicity and efficiency. It is widely used in educational settings due to its straightforward design, making it an excellent teaching tool. The MIPS instruction set is characterized by a fixed instruction length of 32 bits, simplifying decoding and execution. Instructions are categorized into arithmetic, logical, load/store, and branch instructions, each with specific formats and functions.
MIPS employs a load/store architecture, requiring data to be loaded into registers before processing and stored back if necessary. This approach differs from architectures that allow direct memory operations. The consistent instruction format aids in pipelining, enhancing processor performance.
The architecture includes 32 general-purpose registers for temporary data storage. Understanding their use is crucial for grasping instruction operations. MIPS uses various addressing modes, primarily register and immediate addressing, to specify operands. Examples of key instructions include “add” for arithmetic, “lw” (load word) and “sw” (store word) for data transfer, and “beq” (branch if equal) for control flow.
MIPS assembly language provides a human-readable representation of machine code, using mnemonics like “add” and “lw.” Each assembly instruction corresponds to one machine code instruction, translated by an assembler. The evolution of MIPS has introduced new features, with versions improving performance and functionality. Comparing MIPS to other architectures, like x86, highlights RISC’s simplicity versus CISC’s complexity.
MIPS processors are commonly found in embedded systems and networking devices, balancing performance and power efficiency. The architecture’s advantages include fast execution and low power consumption, though it may require more instructions for complex tasks. Its simplicity makes it a popular choice in education, illustrating fundamental computer architecture principles without complexity. The book also covers MIPS microprocessor design using HDLs like Verilog and VHDL, providing practical implementation insights.

Memory systems and hierarchies are critical components of computer architecture, ensuring efficient data access and processing. The hierarchy typically includes cache memory (L1, L2, L3), main memory, and virtual memory. Cache memory acts as a fast buffer between the processor and main memory, reducing access times. Main memory provides larger storage for active data, while virtual memory extends capacity by using disk storage. The book explains how these layers interact to optimize performance, emphasizing the importance of memory management in modern computing systems. Practical examples and diagrams illustrate the design and optimization of memory systems, essential for understanding computer architecture.
