associative mapping with a main memory

2)Assume we are using 2-way set associative mapping with a main memory of 1MB and a cache that holds 1KB. Each cache block contains 32 bytes and cache is initially empty.

1. Complete the table below. (You must use hexadecimal numbers for all answers.)
2. Does any of the addresses cause a collision? If your answer is either yes or not, you must clearly explain why?

3)Given the following sequence of instructions:
    LDUR R1, [R4, #100]

    AND R8, R1, R3

    CBZ R2, Label

    SUB R10, R1, R7

Assuming the register file can be read and written in the same cycle and there is a single memory unit

1. Outline pipeline stages for each instruction (per cycle) (you can create a table for this) and number of cycles it takes to complete this sequence.
2. Identify if there are any hazards or not. If any hazard, explain the type of hazard and how could be fixed?

4)Suppose we have a memory system with a virtual address space of 2⁸ bytes and physical memory of 4 page frames where each page is 32 bytes in length:

1. How many bits does each virtual address have? Show your work.
2. How many bits does each physical address have? Show your work.
3. Each virtual address is divided into two fields: the page field and the offset field. How many bits are allocated for the page field and how many bits are allocated for the offset field? Show your work.
