The computer architecture is a set of disciplines which describes the organization, implementation and functionality of computer systems. It defines how the internal organization of various components and system is designed and implemented to meet the specified capabilities. Computer architecture involves many aspects which includesInstruction Set Architecture, Micro Architecture, Logic Design etc. A computer architecture simulator is a piece of software to model computer devices to predict outputs and its performance metrics on a given input. These simulators can be an instruction set simulator which models a target Microprocessor or a full system simulator whose model includes a processor, a memory system, I/O devices etc. As on today, the instruction set simulator available in the industry uses only a single type of processor (either 8085 or 8086 and so on). This single instruction set simulator has the limitation that at a given time only one type of microprocessor can be simulated between different log-in (any other limitation). To, overcome this, we propose a new integrated computer architecture simulation framework which integrates all microprocessors on a single IDE environment, for better understanding, development, and programming of architecture. © Research India Publications.
