Problem 8: (11 pts) Part 1: (3 pts) Consider the following code: lb x5, 0(x10) sd x5, 8(x10) 4 Assume that register x10 contains address
Problem 8: (11 pts) Part 1: (3 pts) Consider the following code: lb x5, 0(x10) sd x5, 8(x10) 4 Assume that register x10 contains address 010000000 and the data at address is 07FEEDDCCBBAA9987. Q 1: What value is stored in 010000008 on a big-endian machine? Q 2: What value is stored in 010000008 on a little-endian machine? Part 2: (5 pts) Write the RISC-V assembly code that creates the above 64-bit constant and stores that value to register x11. Part 3: (3 pts) Provide the instruction type, assembly language instruction, and binary representation of instruction described by the following RISC-V fields: opcode=0x3, funct3=0x3, rs1=27, rd=3, imm=0x4 Solution:
