1. [20 Points] True or False? (1) Computer architecture is the science and art of selecting and interconnecting hardware components to create computers that meet functional, performance and cost goals. (2). One of the four MIPS design principles is Make the Common Case Fast, meaning that all instructions share a single size in the MIPS design. (3). The stack architectures have low hardware requirements. (4) In most cases users are concerned with how fast processor hardware can perform basic functions. (5) Moore's Law gives a quick way to find the speedup from some enhancements. (6) Instruction set architecture (ISA) serves as an interface between software (e.g., Operating Systems) and hardware. (7) The only control signal that depends on the funct field is the ALUSrc" signal. (8) If performance is the most important design issue, then we must use variable length instructions. (9) To implement a single cycle processor, we should break up instructions into steps, each step takes a cycle. (10) During the instruction-fetch phase, the program counter is increased by four (4)
