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.

How can you find out what coprocessor you have?
Modern computers typically do not use a coprocessor. Floating-point capabilities are built into the CPU.

Is there microprocessor with the name 80487?
No. An 80487 would have been a math coprocessor for an 80486 general-purpose microprocessor...just like the 8087 was the math coprocessor for the 8086 and 8088, the 80287 for the 80286, and the 80387 was for the 80386. The 80486 was the first Intel processor to contain an on-chip math coprocessor, so there wouldn't have been an 80487 because it wasn't necessary.
How does the 8087 coprocessor work?
the 8087 is a numeric data processor(NDP) it is basically made to work with 8086/8088 processors.it cannot fetch its instruction by own so its buses(address and data buses)are simply connected to the respective buses of the processor.its instruction are recognized by the word F because each and every instruction of this coprocessor starts with the word F.this is how the min processor distinguishes between its own and the coprocessor instructions.(eg):-FADD,FSUB,etc.this coprocessor has 8-registers eacch capable of storing 80-bit temporary real numbers. the BUSY pin of the coprocessor is connected to the main processor's TEST pin.this TEST pin is active low in nature.this is because the speed of operation of the coprocessor and the main processor is different. the need of this coprocessor is because the calculation speed of maths operations containing floating real numbers is very fast than the processors like 8086/8088.during the execution of the program if the processor encounters the instruction starting with F word(11011)then it simply gives control to the 8087.initially the coprocessor is initialized by loading it with the control word which gives the idea to the 8087 that which exceptions are to be ignored.usually after the calculations the status word of the coprocessor is loaded to see which errors hve occurred.
Which processor first integrated the math coprocessor in the CPU chip?

Difference between coprocessors and main processor?
A coprocessor provides auxiliary functions or features that the main processor does not have. These might include floating point support or hardware encryption. A coprocessor is generally not usable without its main processor, whereas a processor may function in a crippled or less powerful form without a coprocessor. An example of a processor and a coprocessor pair would be the 80386 and the 80387.
Can real number arithmetic be done without the use of a coprocessor?
Of course! People were doing real arithmetic long before the first computer!

What does 80486 microprocessor from Intel consist of?
It contains a 32 bit CPU, a floating-point math coprocessor, unified instruction and data cache memory and memory management unit in a single IC.
What does Intel 486 mean?
The Intel 80486 was a microprocessor family produced by Intel introduced in 1989. It was their first 86 processor with a math coprocessor built into it. It's predecessor family were the 386 family and it's sucessor was the Pentium chip
