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.

Question

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.
Show all the steps.

A cache is organized as a 4 way set associative cache Each set's cache line consists of 4 words (meaning there are 16 bytes per line, for each set of the cache). Each set individually has one Valid bit, and one Dirty bit, for each line. The tag field of this cache is 8 bits wide. The address is 32 bits wide. Question 1a) What is the number of cache lines? Question 1b) What is the total number of 'memory bitcells' that are needed to design this cache (note, this includes the bitcells required for the tags, valid and dirty bits).

A memory hierarchy contains a single cache with a miss rate of 2% that holds both instructions and data. The miss penalty to access main memory is 100 cycles. 15% of the instructions are jumps, 20% are stores, 20% are loads (30% have values used in the next instruction), 10% are branches (taken 20% of the time), and 35% are ALU instructions. Jumps and branches are determined in the ID stage. What is the base CPI, and what is the effective CPI?
