a) If the access pattern is randorm,we can assume that the latency to fetch
each word will be 7 cycles. This will lead to a bandwidth of
(133 MHz)(8 byte/transfer)/(7 cycles/transfer)=152 Mbytes/sec
b) If we assume that each cache transfer takes 1 clock cycle. Then the
effective average latency is:
(7)(0.05)+(1)(0.95)=1.3 clock cycles.
Thus the overall bandwidth will be
(133 MHz)(8 bytes/transfer)/(1.3 cycles/transfer)=818 Mbytes/second.

Given +1 degree of temperature, directly solve for the required R2
i.e. delta T=+1, R2=?
