August 21, 2008 6 Importance of Technology New technologies not only provide greater speed, size and reliability at lower cost, but more importantly these dictate the kinds of structures that can be considered and thus come to shape our whole view of what a computer is. —e.g. Is there a multiply instruction? Computer Organization , Hamacher, TMH 2. Generally, memory/storage is classified into 2 categories: Volatile Memory: This loses its … Knowledge of digital circuit 2. Computer System Architecture, Morris Mano, PHI Reference Books: 1. A memory element is the set of storage devices which stores the binary data in the type of bits. •Organization is how features are implemented —Control signals, interfaces, memory technology. It is compatible with most off-the-shelf computer programs and applications. A virtual memory system provides a mechanism for translating program-generated addresses into correct main memory locations. Flash memory technology is a mix of EPROM and EEPROM technologies. In general, the storage of memory can be classified into two categories such as volatile as well as non- volatile. The name, therefore, dis-tinguishes flash devices from EEPROMs, where each byte is erased individually. CS152 Computer Architecture and Engineering Lecture 19 Locality and Memory Technology - Title: CS152 Computer Architecture and Engineering Subject: Memory Technology Author: John Kubiatowicz Last modified by: Bob Brodersen Created Date | PowerPoint PPT presentation | free to view Flash memory technology is today a mature technology. A memory unit is the collection of storage units or devices together. The memory hierarchy design in a computer system mainly includes different storage devices. Assume some background information from CSCE 430 or equivalent Virtual Memory is a concept used in some large computer systems that permit the user to construct programs as though a large memory space were available, equal to the totality of auxiliary memory. This extra memory is actually called virtual memory and it is a section of a hard that's set up to emulate the computer's RAM. In the late l950's and early l960's, the gap was wide enough between memory technologies and eventually, to high-level procedural languages. Paging technique plays an important role in implementing virtual memory. It provides excellent performance and value. Internal Memory Computer Organization and Architecture Semiconductor main memory • Early computers used doughnut shaped ferromagnetic loops called cores for each bit • Main memory was often referred to as “core” memory or just “core” • Term persists: e.g. Architecture & Organization 1 •Architecture is those attributes visible to the programmer —Instruction set, number of bits used for data representation, I/O mechanisms, addressing techniques. Download Computer Memory PPT | PDF | Presentation: Memory is an internal storage area in a computer, which is availed to store data and programs either permanently or temporarily. Memory Hierarchy in Computer Architecture. I made some modifications to the note for clarity. Computer Architecture & Organization, William Stallings, Pearson Prerequisite 1. —e.g. Memory Organization in Computer Architecture. computer architecture, mid-2000s onward. AMD : The AMD computer processor is exclusively made by Advanced Micro Devices, Inc. (AMD). The term ÒflashÓ was chosen because a large chunk of memory could be erased at one time. Advancing software technology allowed programming to move to the assembly language level and, denser and faster, the number of registers and the complexity of the instruction sets were increased.
