While executing a program, the microprocessor needs to access memory frequently to read instruction codes and data stored in memory and the interfacing circuit enables that access.

What are the parts of a microprocessor?
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.
What is execution unit and bus interface unit?
In the 8086/8088, the execution unit is the part of the processor known as the CPU. It executes the instructions and generates the results. The bus interface unit, on the other hand, is the part of the processor that handles reading and writing to memory. The two are somewhat loosely coupled, with the bus interface unit attempting to always be ahead of the execution unit, i.e. using the cache, so that the execution unit's wait time is minimized and performance is maximized.
What is a microprocessing unit?
A microprocessor with its external memory, input/output interface devices, and buffer, clock, and driver circuits. Abbreviated MPU.
Which memory is difficult to interface with processor?
dynamic memory
Which processing unit of the 8088 is the interface to te outside world?
The Bus Interface Unit (BIU)
What is the future type of external memory?
If you mean after external hard drives, probably am 80 GB credit card. MSM9841 and MSM9842 offers two types of memory interface: interface when DMA controller is used (16-bit bus) that memory interface is through DMA controller; interface without DMA controller that memory interface (16-bit bus) is through CPU.
How does bus interface unit work with execution unit?
The execution unit execute the instruction while the bus interface unit do the fetching and shows the results as an output
How Memory interface with CPU indicate the direction of signal and control signals?
How Memory interface with CPU indicate the direction of signal and control signals?
What is a bus interface unit?
The bus interface unit is the part of the processor that interfaces with the rest of the PC. Its name comes from the fact that it deals with moving information over the processor data bus, the primary conduit for the transfer of information to and from the CPU. The bus interface unit is responsible for responding to all signals that go to the processor, and generating all signals that go from the processor to other parts of the system.
What is the unit of memory?
The largest unit of memory is a Yoda Byte. :)
What is PIU in telecom?
Power interface Unit.
What is a CPU memory unit?
RAM is generally measured in Megabytes or Gigabytes
