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 is queue status 8086?
queue of 8086 microprocessor is 6 bits
What is the use of insertion queue in 8086?
Maybe you mean the prefetch queue?
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 is difference between job queue and ready queue?
Ready queue contain all the jobs that are ready to execute.so the job queue and the ready queue are one and the same.
What is queue status 8086?
queue of 8086 microprocessor is 6 bits
What is the use of insertion queue in 8086?
Maybe you mean the prefetch queue?
What is size of instruction queue of 8086?
6 bytes
What is the length of the instruction queue in 8086?
6 bytes
What is the size of the instruction queue in 8086?
In 8086 the instruction queue is 6 byte long. This is because even the longest 8086 instruction is 6 byte long. Thus it is possible to prefetch even the longest instruction in the instruction set.
Why Intel kept the name 8086?
in 8086, there is instruction queue of 6 byte. It is one of the reason behind giving name. 8086 was introducing pipeline architecture.

What is cache in 8086?
8086 is a small 4 or 6 byte instruction cache or queue that perfetched a few instructions before they were executed. In addition, the 8086 addressed 1M byte of memory, which is 16 times more than 8085. N.K.Jha narayankumarjha2010@gmail.com

What is an instruction queue in 8086?
The 8086/8088 instruction queue is a buffer that holds opcode bytes that have been prefetched by the bus interface unit. This speed up operations of the processor by helping to reduce fetches latency, i.e. to improve the probability that an opcode byte fetched by the processor is already available. This works best when there is no branching, as a branch would invalidate the queue. Advanced processors attempt to "predict" the branch, making the probability even better.
