8085 Microprocessor

In this method, an I/O device is treated as a memory location. The microprocessor uses 16- bit address to identify and I/O device. Thus the memory map is shared between memory and I/O devices. Memory-mapped I/O uses the same to address both memory.

Non-programmable I/O Port: It behaves as an input port if it has been designed and connected in input mode. Similarly a port connected in output mode acts as an output port. Example: INTEL 8212 Programmable I/O Port: It can be programmed to act either.

Coprocessor is a single chip built for performing scientific computations at high speed. This chip is a companion to the original or host processor. A coprocessor is a computer processor used to supplement the functions of the primary processor (the.

Latch: A bistable circuit that is set and reset by appropriate input signals. An electronic circuit that records the status of a signal until it is reset. A latch is a kind of bistable multivibrator, an electronic circuit which has two stable states.

Packed BCD: Packed BCD Numbers are stored in two digits to a byte, in 4 bit groups referred to as nibbles. ALU is capable of performing only binary addition and subtraction, but.

Real Time Systems are those in which timeliness is as important as the correctness of the outputs, although this does not mean that they have to be “fast systems.

1. Patient Monitoring in Intensive Care Unit. 2. Pathological Analysis and the measurement of parameters like blood pressure and temperature. 3. Measurement of heart activity. 4. Ultrasound Processing unit. 5. MRI scanning 6. CT scanning et.

Assembly Language: It  is human understandable language that is written by language. It is a medium of communication with a computer in which programs are written in mnemonics. Binary instructions are given abbreviated names called mnemonics,.

System Bus: The System bus is a communication path between the microprocessor and peripherals. It is nothing but a group of wires .

CPU is a heart of the computer. Central processing Unit controls the operation of the computer. In a microcomputer the CPU is a microprocessor. The CPU fetches binary coded instructions from memory, decodes the instructions into a series of.

Microprocessor is a multipurpose, programmable, clock-driven, register based electronic device that reads binary instructions from a storage device called memory, accepts binary data .

The physical components of the system i.e. computer are called Hardware. Group of programs is called software. Program is set of instruction that is used to perform a particular instruction. Example: 1. Now we are taking example of a P.
