Question

32 bytes of memory. 16 bytes of fully set-associative cache, where blocks can go anywhere within the set Block is 4 bytes, set in cache is two blocks. Populate memory starting with 0-9, then upper case letters. Hint- with full associativity in the set: blocks are assigned to sets and load in the cache in the correct set The following address requests will load the cache Memory is not organized by sets but by blocks, though

00110
00011
10000
10111
The CPU then generates address 10101. If this address is in the cache, respond with the requested byte.

Answer 1

The last CPU-generated address 10101 is not in the cache and requires a new memory fetch. In computer memory terminology, one million bytes is known as a megabyte (MB).

Step-by-step explanation:

The question relates to computer memory and cache operation in a fully associative cache system. When analyzing the CPU address requests provided (00110, 00011, 10000, 10111), it becomes clear that they correspond to specific memory blocks that are loaded into the cache. Assuming the cache is initially empty and filling it with the first four blocks requested, the last CPU-generated address (10101) is not currently in the cache since it was not among the addresses listed to be loaded. This means the requested byte cannot be provided from cache, as it requires a new memory fetch.

In terms of data measurement in computer memory, the unit for one million bytes is commonly referred to as a megabyte (MB).
