Can someone explain how they'd get the answer to this
problem step-by-step?
4.7 Suppose a 32-bit instruction takes the following format: | OPCODE SR DR IMM . If there are 60 opcodes and 32 registers, what is the range of valucs that can be represented by the immediate (IMM)? Assume IMM is a 2's complement value.

Consider a machine which implements an ISA in which every
instruction is 32 bits long and has the following format:
Where DR = Destination Register, SR = Source Register, and
IMMVAL = Immediate Value. The fields DR, SR are represented using
the same number of bits.
If there are 7 bits for the opcode and 16 registers,
A.) How many unique opcodes can be represented?
B.) What is the minimum number of bits required for the source
register (SR) field?...
Suppose a computer has 20-bit instructions. The instruction set consists of 32 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The frst of these addresses must be a register, and the second must be memory. Expanding opcodes are not used. The machine has 16 registers. What is the maximum allowable size for memory? o 2 K byte O 14K byte O 11 K byte Next » ous

(d) 7650 (e) None of the above Question 7 [18 Points]-Instruction Set Architecture (ISA) I. Suppose an instruction set has 32-bit instructions. Every instruction has an 8-bit opcode and a 12- bit immediate operand. Some instructions have three register operands (two sources and a destination register). Every instruction that uses registers must be able to specify any of the registers. How many registers can this instruction set support? (a) 32. (b) 64. (c) 16. (d) There is not enough information...
Question 20 5 pts Suppose a computer has 32-bit instructions. The instruction set consists of 64 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register direct address, and the second must be a memory address. Expanding opcodes are not used. The machine has 16 registers. What's the size of the largest memory space that can be addressed by this computer?Assume byte addressable memory.

The following 32-bit hexadecimal number describes a RISC-V machine instruction. Decode this instruction into a RISC-V assembly language statement (like `add x0, x1, x2`). To receive partial credit, you should show your steps including converting to binary format and identifying opcode, funct3, rs1, etc. 0x00C1F963
Consider a hypothetical microprocessor generating a 16-bit address (for example, assumethat the program counter and the address registers are 16 bits wide) and havinga 16-bit data bus.a. What is the maximum memory address space that the processor can access directlyif it is connected to a “16-bit memory”?b. What is the maximum memory address space that the processor can access directlyif it is connected to an “8-bit memory”?c. What architectural features will allow this microprocessor to access a separate“I/O space”?d. If...
5) True or False. HALT is actually a TRAP instruction. Using operate type instructions only place the value 45 in RI . 6) 7) True or False. In a Von Neumann machine data and instructions both reside in memory. What is the opcode for GETC in LC-3. 8) (i)True or False. In LC-3 all memory can be accessed with 16 bits.

Goals: To learn general-purpose register architectures. To learn encoding an instruction set. Questions: 100 points: (1) 30 points, (2) 70 points 1. (30 points) The design of MIPS provides for 32 general-purpose registers and 32 floating-point registers. If registers are good, are more registers better? List and discuss as many trade-offs as you can that should be considered by instruction set architecture designers examining whether to, and how much to increase the numbers of MIPS registers. 2.
