1) Consider the instruction slt, which has the format: slt $rd, $rs, $rt. a. The instruction sets $rd to 1 if and only if $ < $. Otherwise it sets $rd to 0. i. Provide an informal RTL (register transfer language) describing the instruction semantics ii. Explain the way that the instruction is mapped into Figure 4.38 from the book by Patterson (enclosed and available on TRACS). The explanation should include the input, output, and role of each CPU unit during the IF, ID, Exe, Mem, and WB cycles of the instruction
