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.
What is the length of the instruction queue in 8086?
6 bytes
What is the maximum length of an instruction in bytes for the 8086 based IBM PC?

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 queue status 8086?
queue of 8086 microprocessor is 6 bits
What is the size of the instruction queue in 8088?
no
What is the size of the instruction queue?
32 byte
Why is size of instruction queue of 8086 fixed to 6 bytes?
An instruction queue is used in the 8086 to speed up the average time it takes to process an instruction. Some instructions are faster than the bus, while some are slower. If the CPU had to wait for all of the instructions, there would be gaps of time where the CPU is doing nothing. The queue helps to eliminate that gap by prefetching instructions in the hope that they will be ready for use when the CPU gets to them.
Why 8086 has 6 byte que?
Because that's how Intel designed it. They chose a 6 byte queue in the 8086 in order to optimize speed versus latency of the execution unit versus the bus interface unit. The decision for 6 bytes, as compared to 4 or 8 or some other number was a cost tradeoff and a recognition of the average mix of instruction execution cycle times in a typical processing thread.
Advantages of 16 bit queue in 8086?
The 16-bit queue in the 8086 microprocessor allows for efficient instruction pre-fetching, which enhances overall performance by enabling the CPU to fetch multiple instructions ahead of time while executing the current one. This results in reduced instruction wait times and improved instruction throughput. Additionally, the 16-bit architecture facilitates better memory addressing and data manipulation, making it suitable for handling larger data sets compared to an 8-bit architecture. Overall, the queue system in the 8086 contributes to a more streamlined and faster execution of programs.
What is the use of insertion queue in 8086?
Maybe you mean the prefetch queue?
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
