How do you interface a clock and microprocessor?
The interface in a microprocessor is an integrated circuit that performs the basic functions of the central processing unit. It enables a user to communicate with a computer.
the principle function of memory interfacing is to enable the microprocessor to read or write into a register of the memory chip
The basic difference between the microprocessor and microcontroller is that we can interface a microcontroller directly means "for example we can directly connect a keyboard to microcontroller to any of its ports"....where as for microprocessor we can't interface directly...we require a circuit board since it requires ram,ic's.....etc.,! beyrojac mahinay
Microprocessor is a programmable logic device which has computing and decision making capability similar to a cpu of a computer..the versions of microprocessor is 8085,8086,8088..
Socket PAC418 is a 418 pin microprocessor socket designed to interface an Intel Itanium processor to the rest of the computer (usually via the motherboard). It provides both an electrical interface as well as physical support. This socket is designed to support a microprocessor module.
A CPU or Central Processing Unit is generally what is meant by the term microprocessor. Sometimes microprocessor can refer to additional hardware, but by and large, CPU = microprocessor.
It means an 8 bit parallel I/O interface, as opposed to 8251 which is a serial I/O.
A microprocessor with its external memory, input/output interface devices, and buffer, clock, and driver circuits. Abbreviated MPU.
The microprocessor contains the CPU of a microcomputer. It is composed of the Arithmetic Logic Unit, Cache Memory (optional), Memory Management Unit (optional), Bus Interface Unit, Control Unit, Instruction Decoder, and Registers.
The need for a timing diagram for a microprocessor is, primarily, to allow you to properly design the interface logic that will support the microprocessor. You need to know what lines are used to execute various data transfers, what are the timing of those lines with respect to each other, and how the microprocessor expects the external logic to behave. You can also use the timing diagram to understand how the microprocessor functions and, particularly, to know how long each instruction will take.
The Instruction Pointer (IP) in an 8086 microprocessor contains the address of the next instruction to be executed. The processor uses IP to request memory data from the Bus Interface Unit, and then increments it by the size of the instruction.
