NEED help with this pl Processor 1 has a clock speed of 4.0 GHz with 32 KiB of L1 cache.

Processor 2 has a clock speed of 2.0 GHz with 64 KiB of L1 cache.

In order to decide which to buy, you estimate the time each processor will take to load a program with 10 000 RISC instructions into the processor’s registers and the time to execute the instructions.

Each RISC instruction has a size of 4 bytes.

Each RISC instruction takes one clock pulse to execute once it is in the registers.

i. Show that a program consisting of 10 000 RISC instructions will fit into 64 KiB of L1 cache but will not fit into 32 KiB of L1 cache.

ii. It takes 1 nanosecond (1 × 10-9 s) to move an instruction from L1 cache to the registers and 9 nanoseconds to move an instruction from L2 cache to the L1 cache. Assume that for Processor 2, all of the instructions can be found in L1 cache; and for Processor 1, all of the instructions that won’t fit in L1 cache can be found in L2 cache.

How much time is needed to load all 10 000 instructions into the registers for each processor? Write your answers in seconds, using scientific notation.

iii. For each processor, calculate the time it takes to execute 10 000 RISC instructions. You should not include the time to load the instructions into the registers here. Write your answers in seconds, using scientific notation.
