StingyMIPS is a 5-stage pipelined implementation of MIPS without forwarding. The code below contains data hazards. Rewrite this code so that it does the same thing on StingyMIPS as on regular MIPS, but runs without stalls on StingyMIPS. A stall delays every subsequent instruction by 1 cycle.
WebRAW hazard can be referred to as 'Read after Write'. It is also known as Flow/True data dependency. If the later instruction tries to read on operand before earlier instruction writes it, in this case, the RAW hazards will occur. The condition to detect the RAW hazard is when O n and I n+1 both have a minimum one common operand. For example: http://ecen323wiki.groups.et.byu.net/labs/lab-09/
