Noun
coprocessor (plural coprocessors)
(computer hardware) An additional microprocessor used to supplement the functionality of the central processing unit, performing tasks such as floating-point arithmetic (floating-point unit) or graphics calculations (graphics processing unit).
All registers are accessed through standard ARM architecture coprocessor mapping mechanism. iwMMXt occupies coprocessors 0 and 1 space, and some of its opcodes clash with the opcodes of the earlier floating-point extension, FPA. Source: Internet
An Intel 80287 A floating-point unit (FPU, colloquially a math coprocessor) is a part of a computer system specially designed to carry out operations on floating point numbers. Source: Internet
Accelerator support: Take advantage of high-performing accelerators such as GPGPU and Intel Xeon Phi coprocessor. Source: Internet

Floating point The 8086/8088 could be connected to a mathematical coprocessor to add hardware/microcode-based floating point performance. Source: Internet
In ARM-based machines, peripheral devices are usually attached to the processor by mapping their physical registers into ARM memory space, into the coprocessor space, or by connecting to another device (a bus) that in turn attaches to the processor. Source: Internet
