# What is a math coprocessor?

## What is a math coprocessor?

A mathematical circuit that performs high-speed floating point operations. Also called a “floating point unit” (FPU), the math coprocessor may be a stand-alone chip or circuits built into the CPU. A spreadsheet may use floating point operations if the circuits are available, but it is not mandatory.

## Which chip has a built in math coprocessor?

The Intel 80386 microprocessor used an optional “math” coprocessor (the 80387) to perform floating point operations directly in hardware. The Intel 80486DX processor included floating-point hardware on the chip.

**What are coprocessor chips?**

A coprocessor is a special set of circuit s in a microprocessor chip that is designed to manipulate numbers or perform some other specialized function more quickly than the basic microprocessor circuits could perform the same task. Some coprocessors are still available as separate chips or circuit cards.

### Why do we need a math coprocessor?

The math coprocessor was an optional add-on for the Intel 8086, 80386 and 80486 processors that allowed computers to perform faster mathematical calculations, increasing its overall performance. Today, all computer processors are released with a math coprocessor incorporated onto the processor.

### What is the purpose to use a coprocessor?

coprocessor, additional processor used in some computers to perform specialized tasks such as extensive arithmetic calculations or processing of graphical displays.

**What is the function of math coprocessor chip?**

A math coprocessor is a computer chip that handles the floating point operations and mathematical computations in a computer. In early PCs, this chip was separate and often optional, and it was primarily used in computers where Computer Aided Design (CAD) was the primary focus.

#### Which of the processor has an internal coprocessor?

Which of the processor has an internal coprocessor? Explanation: 8087 is an external IC designed to operate with the 8088/8086 processor but 80486DX is an on-chip coprocessor that is, it does not require an extra integrated chip for floating point arithmetics.

#### Is a GPU a coprocessor?

It consists of multiple SIMD multiprocessors, and has a large amount of device memory.

**What is a coprocessor used for?**

## What is difference between processor and coprocessor?

The difference between processor and Coprocessor is that the processor is the main processing unit of the computer that performs arithmetic, logic and control operations according to the instructions while the coprocessor is a specialized processor that supports the main processor.

## How does a coprocessor work?

By taking specialized processing tasks from core CPU, coprocessor reduces the strain on the main microprocessor, so that it can run at a greater speed. A coprocessor can perform special tasks like complex mathematical calculations or graphical display processing. They perform such jobs faster than core CPU.

**What is FPU in computer?**

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. Typical operations are addition, subtraction, multiplication, division, and square root.

### What kind of chip is a math coprocessor?

A math coprocessor is a computer chip that handles the floating point operations and mathematical computations in a computer. In early PCs, this chip was separate and often optional, and it was primarily used in computers where Computer Aided Design (CAD) was the primary focus.

### Is the Intel 487 the same as a 387?

The Intel 487 “math coprocessor” for 486SX users was in reality a CPU replacementâ€”a 486DX with a different pinoutâ€”and originally cost several hundred dollars more than a 387.

**Why do I need a coprocessor in my computer?**

Applications on a PC, like a CAD program or even a spreadsheet, that deal with floating point units (FPUs) and calculations relay on this coprocessor to assist in performing these calculations. This leaves the CPU more available for operating system tasks and overall PC management.

#### Is the Cx486DLC the same as the Intel 486?

The Cyrix Cx486DLC was an early 486 CPU from Cyrix, intended to compete with the Intel 486SX and DX. Texas Instruments, who manufactured the 486DLC for Cyrix, later released its own version of the chip, the TI486SXL, with 8 kB internal cache vs 1 kB of the original Cyrix design.
