How many bytes are there for jump instruction in 8085?
There are 74 instructions in the 8085 microprocessor.
What is size of instruction queue of 8086?
6 bytes
What is the length of the instruction queue in 8086?
6 bytes
Which instruction in 8086 microprocessor is 6 bytes long?
mov
Why the length of instruction queue is 6 bytes?
increases speed
What is 3 byte instruction in microprocessor?
A two-byte instruction gives the specific function instruction in two bytes, or two words. The first specifies the opcode, which tells the microprocessor what operation will occur. The second specifies the operand, or the data that the operation is done on.
Difference between code segment and data segment of an instruction?
In the 8086/8088 microprocessor, the code segment is used to fetch the opcode and any additional instruction bytes that might be part of the instruction, while the data segment is used to fetch and/or store any operand bytes that the instruction requires to be manipulated.This is in the case of no segment override prefix.
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 happens to ip after completion of fetch of instruction code?
IP is incremented after fetch of instruction opcode. Specifically, IP is incremented by the number of opcode bytes.
What is the operational difference between the IRET and RET instruction?
Both are used for Return operations. But the difference is IRET uses extra 2 bytes along with 2 bytes(making it 4 bytes) for poping from stack. And RET uses only 2 byte of instruction for Poping. IRET is used to switch from Virtual Mode to Protected Mode whereas RET isn't.
What is the need of instruction pointer?
IP(instruction Pointer) is a processor Register IP store the offset address of the next instruction IP can be modified by Jump & call condition IP can Increment by 1,2,3.......bytes Regard:tiger_ucet@yahoo.com
What is a measurement of how much information can be sent or processed with one single instruction and is calculated in bit or bytes?
Word length.
