Please give thumbs up if you like it.I have completed the problem
Step 1 :-
Data given is
Direct mapped cache
=>Cache Block Size is 1Byte
So,Block offset will be = log 1 = 0 bits
=> Number of Blocks are = 4
Sp,Index bits will be = log 4 = 2 bits
=> Total bits of References is 12 bits
So,Tag bits will be = (12 - 2)= 10bits
Step 2 :-
We will check all references whether it is hit or miss by checking tag bit of particular index if its matches then it is hit otherwise there is miss
Every Memory references shown below and showed about hit/miss,tag and index

Question 3: Consider a 32-bit physical address memory system with block size 16 bytes and a 32 blocks direct mapped cache. The cache is initially empty. The following decimal memory addresses are referenced 1020, 1006, 1022, 5106, 994, and 2019 Map the addresses to cache blocks and indicate whether hit or miss. Note: You must use the hexadecimal approach in solving this question. You must also show the computations of dividing the memory address into tag bits, cache index bits,...

Assume the cache can hold 64 kB. Data are transferred between main memory and the cache in blocks of 4 bytes each. This means that the cache is organized as 16K=2^14 lines of 4 bytes each. The main memory consists of 16 MB, with each byte directly addressable by a 24-bit address (2^24 =16M). Thus, for mapping purposes, we can consider main memory to consist of 4M blocks of 4 bytes each. Please show illustrations too for all work. Part...
Example 4.2 For all three cases, the example includes the following elements: The cache can hold 64 Kbytes. Data are transferred between main memory and the cache in blocks of 4 bytes each. This means that the cache is organized as 16K = 214 lines of 4 bytes each. The main memory consists of 16 Mbytes, with each byte directly addressable by a 24-bit address (24 = 16M). Thus, for mapping purposes, we can consider main memory to consist of...
Example on Cache Placement & Misses - Can someone explain to me how this is done. Solution is posted Consider a small direct-mapped cache with 32 blocks - Cache is initially empty, Block size = 16 bytes - The following memory addresses (in decimal) are referenced: 0x3E8, 0x3EC, 0x3F0, 0x9F4, 0x9F8. 0x9FC. - Map addresses to cache blocks and indicate whether hit or miss Solution - 0x3E8 cache index = 0x1 E Miss (first access) - 0x3EC cache index =...
3. 12+2-4 points] We are comparing the two caches in Problem 1 and Problem 2. Suppose both caphes have a hit time of 2 cycles. The cache in Problem 1 has a miss penalty of 15 cycles. The one in Problem 2 has a miss penalty of 25 cycles. Calculate the total time taken (in cycles) for all accesses, for each cache. Which cache is better- the one in Problem 1 or Problem 2? 3. 12+2-4 points] We are comparing...
