(a) Compare the properties of CPU registers with the main memory in MIPS.
(b) Describe the purpose of the stack pointer ($sp) for procedure calling.
(c) What is a "basic block" and how is it used by a compiler?
(d) There are no branch instructions in MIPS that perform a comparison test (>, <, etc.). What is the rationale behind not including these instructions, and how are such branches handled?
(e) What are the limitations of conditional branch instructions (beq, bne) in MIPS, and how are such limitations overcome by the assembler?
