    5 RISC: Reduced Instruction Set Computing. In the 1970s, as memory sizes and transistor counts improved, there was a backlash against CISC. Similarly, instructions to load or store values to/from memory require two instructions, as memory addresses are 32-bits whereas the address field in the I-type instruction is only 16-bits: Load/Store: 3 address add Ra Rb Rc Ra = Rb + Rc load Ra Rb Ra = mem[Rb] store Ra Rb mem[Rb] = Ra A load/store architecture has instructions that do either ALU operations or access memory, but never both.

    • In RISCV, only load and store instructions access memory locations • These instructions must follow a format' to access memory • Assume a 32 bit machine in all problems unless asked to assume otherwise Problem 1: (a) Instruction(s) to load Register x5 with content of … In RISCV, only load and store instructions access memory locations; For each RISC-V instruction below show the value of the opcode (op), source register (rs1), and destination register (rd) fields in the 32 bit machine instruction. For the I-type instructions, show the value of the immediate field, and for the R-type instructions, show the
