Why implement 8086 processor to 8087 processor?
The 8086/8088 is the general purpose processor. The 8087 is the math co-processor for the 8086/8088.
Why 8086micro processors are called co- procossers?
The 8086 is not a co-processor. The 8087 is. The 8087 is intended to be coupled to an 8086/8088 to do math co-processing.
What is coprocessor?
Co processor(8087 for 8086,80287 for 80286 etc) is also known as Math processor.It is a dedicated processor for performing arithmetic operations.It has very strong instruction set for numerical operations,faster than 8086 by 4 times.Normally 8086 and other microprocessors will take a lot of time to perform numerical operations and so in multiprocessor mode 8087 will work together with 8086 to solve numerical pronblems. The programmer can write a program with 8086 instructions and 8087 instructions together and so the speed will be improved.
What is TEST pin in 8086 in microprocessor?
TEST This input is examined by a 'WAIT' instruction. If the TEST input goes low, execution will continue, else, the processor remains in an idle state. The input is synchronized internally during each clock cycle on leading edge of clock.
What is a co-processor chip?
A co-processor is a special chip which is used for some special operations like mathematical calculations, graphics and etc in order to reduce the load of the main processor or micro processor.
What is a role of co-preprocessor in c?
Co-processor and pre-processor are two different thing. Pick one.
What is the difference between the 8086 and the 8087?
The 8086 was a 16-bit microprocessor chip. It gave its name to the x86 architecture. It was the main CPU of the computer. The 8087 was the first math coprocessor for 16 bit processors. It was the first of the x87 architecture chips. it couldn't act as the main CPU in a computer, it was dedicated to doing floating point mathematical computations.
What is the roles of the processor?
A processor is a component within the comp. that co-ordinates the hardware and software.
What is the average speed of a processor?
it is very very bad co mputer system
What is a coproccessor driver used for?
A co-processor driver is used for controlling the co-processor which aids your CPU in carrying out some functions such as speeding up media such as graphics and speeding up the number of calculations your CPU can handle.
What does 3 represents in Intel i3 processor?
Dear friends, here, 3 represents......the no. of co-processors working/ attached with the main processor...:-) and similarly for I-5
Diffrentiate between minimum mode and maximum modes in 8086 processors?
1:in min mode mn/mx- is connected to vcc .here now mn will be one AND IN MIN MODE ONLY ONE PROCESSOR IS PRESENT WITHOUT ANY CO PROCESSOR . 2: in max mode mn/mx- is cnnected to ground now the mx will become 1. AND IN MAX MODE MANY PROCESSORS ARE CONNECTED TO EACH OTHER WITHOUT ANY CO PROCESSOR EX FOR COPROCESSOR IS 8284 1:in min mode mn/mx- is connected to vcc .here now mn will be one AND IN MIN MODE ONLY ONE PROCESSOR IS PRESENT WITHOUT ANY CO PROCESSOR . 2: in max mode mn/mx- is cnnected to ground now the mx will become 1.
