The names of the pipeline stages are somewhat less than standard. More common is to use IF (instruction fetch from Instruction Memory IM), ID (instruction decode and register read), EX (execute/ALU), MEM (Data Memory read or write), and WB (write back register result). Whether it is 2 vs. 3 clock cycles depends on your internal architecture.
