3. (15 points) Computations. a. Which endianness does RISC-V choose? Illustrate how a 32 -bit hexadecimal number: " OAOBOCOD " is stored in memory with starting address at 00100. b. Suppose we have two implementations of the same instruction set atchitecture. Computer A has a clock cycle time of 300ps and a CPI of 2.0 for some proyeram, and Which computer is faster for this program and by how much? 4. ( 30 points) Translate below programming statement to RISC-V assembly instructions, then into machine instructions. Present machine instructions in both binary and hexadecimal formats. A[20]=h+A[20]1; Assume 9 has the base of the array A and 10 corresponds to h
