Unformatted text preview: OPCODE | SR | DR | IMM (Opcode, Source Register, Destination Register, Immediate Value) If there are 60 defined opcodes and 32 registers that can be used either for the source and/or destination register, what is the largest positive number that can be represented by the immediate (IMM) field? (Assume IMM is a 2's complement number.) 7. (4 points) The number of instructions per second executed by a processor is measures in millions of instructions per second (MIPS). Why or why not is MIPS a good metric for comparing different machine architectures? 8. (12 points) Match the following terms to the best answer: 2, 4, or 6 1 a R0 Addressing modes 2 b R2 Clock signal 3 c R1 Constant generator 4 d R3 CPU OFF 5 e 27 Destination modes 6 f 7 Instructions 7 g Register operations Program Counter 8 h Instruction length Single Cycle 9 i Status register, bit 4 Stack Pointer 10 j Overflow Status Register 11 k MCLK V 12 l 4 BYU, ECEn/CS 124, W2012 Homework #4 Page 2/2...
