8086 microprocessor architecture and instruction set pdf
How to speed up CPU execution in 8086 microprocessor?
This is called Pipelining which speeds up the execution by reducing CPU waiting state time as illustrated in the below figure. The 8086 microprocessor has 1 MegaByte (2 20 bits = 1 Mb) of segmentized memory divided into 16 logical segments.
What is parallel processing in 8086?
Since, the two operations i.e., fetching an instruction from code memory by bus interface unit and execution of the instruction by execution unit are performed simultaneously, it is called parallel processing. The A-Bus, B-Bus, and C-Bus are the internal buses of the 8086 processor.
What are the features of a 8086 microprocessor?
The most prominent features of a 8086 microprocessor are as follows − It has an instruction queue, which is capable of storing six instruction bytes from the memory resulting in faster processing. It was the first 16-bit processor having 16-bit ALU, 16-bit registers, internal data bus, and 16-bit external data bus resulting in faster processing.
What is a prefetch unit in an 8086 microprocessor?
The Prefetch Unit in the 8086 microprocessor is a component responsible for fetching instructions from memory and storing them in a queue. The prefetch unit allows the 8086 to perform multiple instruction fetches in parallel, improving the overall performance of the microprocessor.
