Microprocess Architecture Pdf Input Output Computer Data In addition to the processor and a set of memory modules, the third key element of a computer system is a set of input output subsystem referred to as i o, provides an efficient mode of communication between the central system and the outside environment. Several memory chips and i o devices are connected to a microprocessor. the following diagram shows a schematic diagram to interface memory chips or i o devices to the microprocessor. Cpu accesses physical memory over a bus devices access memory over i o bus with dma devices can appear to be a region of memory. Arrange the available memory chips so as to obtain 16 bit data bus width. the upper 8 bit bank is called ‘odd address memory bank’ and the lower 8 bit bank is called ‘even address memory bank’.
Microprocessor Architecture Pdf Central Processing Unit Input Output Cpu accesses physical memory over a bus devices access memory over i o bus with dma devices can appear to be a region of memory. Arrange the available memory chips so as to obtain 16 bit data bus width. the upper 8 bit bank is called ‘odd address memory bank’ and the lower 8 bit bank is called ‘even address memory bank’. The input and output devices are differentiated by the control signals; the mpu uses the i o read control signal for input devices and the i o write control signal for output devices. Input and output devices, which are interfaced with 8085, are essential in any microprocessor based system. they can be interfaced using two schemes: i o mapped i o and memory mapped i o. in the i o mapped i o scheme, the i o devices are treated differently from memory. Intel microprocessors have gained wide, and at times exclusive, application in many areas of electronics, communications, and control systems, particularly in desktop computer systems. The function of these components is typically divided into four main categories, these are: central processing unit (cpu), memory unit, i o unit and system interconnection (buses) that provide the communication among the cpu, main memory, and i o.
