(4 points) The following sequence of MIPS instructions is run into the pipeline. Q3.D lw $2,100($0) sub $3,$1,$4 andi $6,$7,8 add $4,$3,50 1. (1 point) Which instruction will be in the ID stage at the third clock cycle (note that the first add instruction was at IF at the first cycle)? 2. (1 point) How many cycles it takes to execute the whole code (the first instruction takes 5 cycles)? 3. (2 point) If the code is to be executed on a single clock cycle MIPS with a clock frequency of 500MHz. what would be the execution time
