What is a computer?. The Computer’s Evolution. Uses of Computer. COMPUTER. It is an electronic device which is being used in a variety of purposes. . It accepts information in the form of digitalized data (inputs) and manipulates these data based on a program or a series of instructions on how the data is to be processed.. J . Srinivasa. Rao. Govt. Polytechnic . Kothagudem. Khammam. 2. Microprocessor. Program controlled semiconductor device (IC) which fetches (from memory), decodes and executes instructions. . It is used as CPU (Central Processing Unit) in computers.. MODULE - I (10 hours) . Microprocessor Architecture: Microprocessor and Microcomputer Architecture, Pins & . Signals, Register Organization, Timing & Control Module, 8085 Instruction Timing & Execution. . Lecture 7: Subroutines and stack framesParameter passing though the stackAn exampleLocal variables and the stack frameand ULNK instructionsParameter passing through stack framesAn exampleThe need for Microprocessors. Micros and Hardwired. A hardwired system can fulfil only the purpose for which it was designed. It uses fixed logic gates and chips to perform its given function. Changing the function of the system requires changing circuitry which is an unrealistic proposition in todays fast changing world..  1,442 sq . km. Population:.  ~ .
