Compute Average Memory Access Time (AMAT) for a system that consists of a 2- level cache design. There the hit rates are 50% for the smaller (L1) cache and 96% for the larger (L2) cache. L1 access time is 1 cycle, L2 access time is 5 cycles, and a memory access time is 20 cycles.

Q: Calculate the Effective Access Time (EAT) by assuming the Hit ratio (?) 95%. Cache Access Time (ε)…

A: Given, Hit ratio (?)= 0.95 Cache Access Time (ε)=20 microsecond Memory Access Time (T) = 100…

Q: Explain the concept of "write-back" and "write-through" cache policies in memory management and…

A: In memory management, two cache policies are Write Back and Write Through.These policies determine…

Q: A processor has an 30-bit physical address space (A memory address is 30-bit). It also has a…

A: I have answered all the 3 parts and have provided detailed solution in the image.  First we will…

Q: Cache access time is 30 ns and main memory access time is 100 ns. What is the total memory access…

A: Effective memory access time = Cache hit ratio*(cache access time) + cache miss*(cache miss…

Q: A cache memory needs an access time of 30 ns and main memory 150 ns, what is the average access time…

A: Here hit rate = 0.80  =  H Miss rate = 0.20  = (1- H) Cache access time = 30 ns = C Memory Access…

Q: cache, 20 ns are required to load it into the L2-cache and reference is started again Main memory…

A: If a word is in L1, the  total access time is 5ns (since we don't need to find anywhere else)  When…

Q: Assume you have a 8-way set associative cache having 16K lines each having capacity of 8 Bytes. A…

A: A.  Block size = 8 bytes So # of data bytes brought= size of block = 8

Q: Assume that a system's memory has 128M bytes. Blocks are 64 bytes in length, and the cache consists…

A: The answer is

Q: The terms "unified cache" and "Hadley cache" need to be defined and explained in terms of what they…

A: To be determined: Explain the difference between a unified cache and a Harvard cache.

Q: (i) to calculate the Cache Entry (2) (ii) as the Cache Tag (2)

A: Cache memory : It the fastest memory of the computer.

Q: Cache computations: Average Memory Access Time is computed: AMAT = Hit time + (Miss rate X Miss…

A: Given that: The cache has a 95% hit rate  & 5% miss rate. We need to find the average memory…

A:

Q: It is important to differentiate between a cache that is completely associative and one that is…

A: Definition: In a full associative cache mapping, every block in main memory can be assigned to any…

Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.
