Computer Architecture: Cache Memory Analysis and Implementation

This assignment analyzes cache memory performance by examining the impact of index bits, tag bits, and block offsets on hit/miss results in three different cache configurations (C1, C2, and C3). The analysis is based on a given memory address sequence and involves understanding how different configurations affect the cache's ability to store and retrieve data efficiently. The configurations differ in block sizes, which influences the index and offset fields. The assignment includes a table of memory addresses, binary representations, and hit/miss results for each configuration. The references include works on the architecture of cognition and transactional memory architecture and implementation.

The table below depicts the index bits, tag bits, block offset bits and hit/miss results of the three
cache configurations:

215 110 10 111 110 101 10 1
In summary, the difference between C1, C2 and C2 are the block- offsets which affects the index
field and though they are all of the same capacity, the tag field remains unchanged for C2 and C3

C1: Index: (8 entries); byte offset: 1:0 (1 word/block)
C2: Index: (8 entries); byte offset: 2:0 (2 word/block)
C3: Index: (2 entries); byte offset: 1:0 (1 word/block)
