2. (6 points) Please answer the following questions in terms of MIPS Architecture and MIPS instruction set How many general purpose registers are available? How many bits are there for the content of each register? How many bits are needed to address each register? a. How many bits are used for memory addresses? Is the memory byte-addressed or word-addressed? What's the largest memory size (in terms of MByte or GRvte) that we can address directly? b. If 6 bits are used for the opcode field, how many different operations can be represented? How does MIPS instruction set provide additional operations in addition to that can be represented by the 6-bit opcode? c
