Computer Architecture and organization • 1. KadamDepartment of Computer Science, Yogeshwari Colloge, Ambajogai. • Electronic Desired Devices Behavior a very wide semantic gap between the intended behavior and the workings of the underlying electronic devices that will actually do all the work.

The forerunners to modern computers attempted to assemble the raw devices (mechanical, electrical, or electronic) into a separate purpose- built machine for each desired behavior.• computer software organization GeneralElectronic Desired Purpose Devices Behavior Computer A general purpose computer is like an island that helps span the gap between the desired behavior (application) and the basic building blocks (electronic devices). •  Computer Architecture = ISA + MO  Instruction Set Architecture  What the executable can “see” as underlying hardware  Logical View  Machine Organization  How the hardware implements ISA?

 Physical View•  Early 1990’s Apple switched instruction set architecture of the Macintosh  From Motorola 68000-based machines  To PowerPC architecture  Intel 80x86 Family: many implementations of same architecture  program written in 1978 for 8086 can be run on latest Pentium chip• Technology Programming Languages Applications Computer Architecture Operating Systems History• software instruction set hardware Examples: 80x86 50,000,000 vs. MIPS 5500,000???• Designing Computers • All computers more or less based on the same basic design, the Von Neumann Architecture!• The Von Neumann Architecture • Model for designing and building computers, based on the following three characteristics: 1) The computer consists of four main sub-systems: • Memory • ALU (Arithmetic/Logic Unit) • Control Unit • Input / Output System (I/O) 2) Program is stored in memory during execution. 3) Program instructions are executed sequentially.• The Von Neumann Architecture Bus Processor (CPU) Memory Input-Output Control Unit ALU Communicate with Store data and program 'outside world', e.g. • Screen Execute program • Keyboard • Storage devices •. Do arithmetic/logic operations requested by program• Simplified Architecture Source: Wikipedia• • Memory Subsystem • Memory, also called RAM (Random Access Memory), – Consists of many memory cells (storage units) of a fixed size.

Each cell has an address associated with it: 0, 1, – All accesses to memory are to a specified address. A cell is the minimum unit of access (fetch/store a complete cell).
