the step the calcul how to convert the kilobytes to know the cache line and the concept ???

Give a description of how one of the cache protocols works.

The hardware used to replicate Pep/9 has 64K memory. But what is its purpose? So far, just 0x0030 of memory has been written. What gives with all that additional RAM, then? How does each memory region in Pep/9 know what to do with it? Another viewpoint There have only been "global" variables utilised. What impact would using "local" variables have? What distinguishes them? (Think of "stack").

Please give me only correct answer

Suppose cache has a hit rate of 0.89 and access time of 5ns, main memory has a hit rate of 0.98 and access time of 60ns, and virtual memory has an access time of 700 us (microseconds). What is the average memory access time in us?

in 8 bit computer system paging is used. how many different virtual memory addresses total? if there are 64 memory address in frame, and page number needs p bits, what is value of p?

Our second task is to check the sign bit of a number. There are many ways to do this, but I want the least expensive method in terms of the number of instructions. This generally means avoiding the use of instructions that has immediate operands. To get to the instruction that we need to use, we first need to examine the ALU itself. Which flag (the corresponding ALU tunnel name in parentheses) in the ALU reflects the sign bit of the result of a computation regardless of the computation, with the exception of the instructions dec and inc? S (Sout) only add and subtract instructions affect S (Sout) O (Oout) C (Cout) B (Bout)

Consider the best way to count how many bits are set in a bitmap. Keeping the size of the cache in mind, what are the trade-offs of choosing a smaller or larger array size?
