Q. Show typical microprocessor system architecture?
A microprocessor system bus consists of three physical buses: the address bus, the data bus, and the control bus. The types of circuits connected to microprocessor buses are registers, accumulators, or buffer circuits between the bus and the external memory or I/O devices. Multiplexing is usually used, which is to connect each register to a bus on a time-shared basis, only when it is being read. An operating bus is used to transfer various internal operations and commands. An interface bus, such as the IEEE-488 (developed in 1975 by the Institute of Electrical and Electronics Engineers) or the GPIB (general-purpose interface bus) provides the means of communicating between the computer and the outside world with external devices such as oscilloscopes, data collection devices, and display devices. Most present-day data acquisition systems are designed to be compatible with microprocessors for processing the measured data. A typical data acquisition and processing system is illustrated in Figure.
DRAM consists of MOSFET's but the technique is to use the drain source capacitance to hold charge. If charge is present logic '1' is held, no charge logic '0'. As you know capacito
