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 do BIU and EU stand for and what are their functions?
biu stands for bus interface unit and eu stands for execution unit. In 8086 microprocessor BIU fetches the instructions and places in the queue. The Eu executes the fetched instruction and places the result in the registers
Explain the function of BIU and EU in 8086?
biu stands for bus interface unit and eu stands for execution unit. In 8086 microprocessor BIU fetches the instructions and places in the queue. The Eu executes the fetched instruction and places the result in the registers
What are the main parts of processor with diagram?
THE PARTS OF THE MICROPROCESSOR ARE; a) CORE b) CODE CACHE c) INSTRUCTION DECODER AND PREFETCH UNIT d) BRANCH PREDICTOR e) INTEGER ALU (arithmetic and logic unit) f) REGISTERS g) EXECUTION UNIT h) 32-BIT BUSES i) FLOATING POINT UNIT j) DATA CACHE k) PRIMARY CACHE l) BUS INTERFACE m) 64-BIT BUSES
Describe the functions of the 8086 queue?
The 8086/8088 instruction queue is a buffer that holds opcode bytes that have been prefetched by the bus interface unit. This speeds up operations of the processor by helping to reduce fetch latency, i.e. to improve the probability that an opcode byte fetched by the processor is already available.
What interface is an interface that uses graphics as compared to a command-driven interface?
Graphical User Interface
