Question:
What is a math coprocessor? Why is it necessary?



Replies:
A math coprocessor is a piece of hardware closely related to the CPU of a computer. The CPU is in effect the brain of the computer. With out the CPU the computer is just a box containing electrical connections. Sometimes computers will use extreme amounts of CPU time to say run mathematical calculations given it by a program. As a result it bogs down the CPU ... it has a hard time doing other operations such as keyboard entry (typing in letters) and the user sees a delay from the time they type in letters until the time they are displayed on the machine because the CPU is busy doing mathematical calculations for some other program. So the math coprocessor was developed to free the CPU from math intensive operations and thus let the CPU do the other operations it was intended to do such as input - output operations and the like. The math coprocessor then takes over these math operations and runs them. This hopefully makes the computer more efficient.
