Memory Systems: Cache, DRAM, Disk
Is your memory hierarchy stopping your microprocessor from performing at the high level it should be? Memory Systems: Cache, DRAM, Disk shows you how to resolve this problem.
The book tells you everything you need to know about the logical design and operation, physical design and operation, performance characteristics and resulting design trade-offs, and the energy consumption of modern memory hierarchies. You learn how to to tackle the challenging optimization problems that result from the side-effects that can appear at any point in the entire hierarchy.
As a result you will be able to design and emulate the entire memory hierarchy.
. Understand all levels of the system hierarchy -Xcache, DRAM, and disk.
. Evaluate the system-level effects of all design choices.
. Model performance and energy consumption for each component in the memory hierarchy.
Why Read This Book
You should read this book if you need a single, thorough reference that explains how caches, DRAM devices, memory controllers and disks behave and interact — and how those interactions drive performance and energy trade-offs. It gives you the vocabulary, analytic techniques, and practical design guidance to model, evaluate, and improve real memory hierarchies.
Who Will Benefit
FPGA designers, hardware engineers and system architects who must design or tune memory interfaces, controllers or system-level data paths for high-performance or energy-constrained systems.
Level: Advanced — Prerequisites: Solid background in digital logic and computer architecture fundamentals (caches, pipelining, virtual memory) and basic familiarity with probability/performance analysis; programming/simulation experience is helpful.

How It Compares
Covers the memory-specific depth that Hennessy & Patterson's Computer Architecture introduces more broadly — Jacob goes deeper into DRAM internals, controller scheduling and disk interactions than most general architecture texts.
