Assume that we have an application with a total of 500,000 instructions where 20% of them are the load/store instructions with an average cpi of 6 cycles, and the rest instructions are alu instructions with average cpi of 1 cycle. if we double the clock rate without optimizing the memory latency, the average cpi for load/store instruction will also be doubled to 12 cycles. what is the speedup after this change?

Clunker motors inc. is recalling all vehicles in its extravagant line from model years 1999—2002 as well as all vehicles in its guzzler line from model years 2004—2007. a boolean variable named recalled has been declared. given a variable modelyear and a string modelname, write a statement that assigns true to recalled if the values of modelyear and modelname match the recall details and assigns false otherwise.
