Ep 067 Introduction To The Memory Hierarchy Youtube Our first look at computer architecture takes us into the memory hierarchy and examines how cost, speed, and capacity change as we move from level to level. This memory hierarchy design is divided into 2 main types: external memory or secondary memory: comprising of magnetic disk, optical disk, and magnetic tape i.e. peripheral storage devices which are accessible by the processor via an i o module. internal memory or primary memory: comprising of main memory, cache memory & cpu registers.
Diagram Of Memory Hierarchy Introduction to the various types of memory commonly used and how they are structured into a hierarchy to maximize performance for your money. Introduces the idea of a memory hierarchy in computer systems, how temporal and spatial locality allow them to achieve their goal, and simple metrics to eval. Eecs 213 introduction to computer systems northwestern university 2 random access memory (ram) key features – ram is packaged as a chip. – basic storage unit is a cell (one bit per cell). – multiple ram chips form a memory. static ram (sram) – each cell stores bit with a six transistor circuit. Figure 7.2.1 7.2. 1: ("memory hierarchy" by rishabhjain12, geeks for geeks is licensed under cc by sa 4.0) this memory hierarchy design is divided into 2 main types: external memory or secondary memory. this level is comprised of peripheral storage devices which are accessible by the processor via i o module. internal memory or primary memory.

Memory access equations. using what we defined on previous slide, we can say: memory stall clock cycles =. reads x read miss rate x read miss penalty . writes x write miss rate x write miss penalty. often, reads and writes are combined averaged: memory stall cycles =. The hierarchical memory system tries to hide the disparity in speed by placing the fastest memories near the processor. memory hierarchy design becomes more crucial with recent multi core processors because the aggregate peak bandwidth grows with the number of cores. for example, intel core i7 can generate two references per core per clock.
