An Intel i387SX (16 MHz – 25 MHz) The Intel 80387SX (387SX or i387SX) is the math coprocessor, also called an FPU, for the Intel 80386SX microprocessor. Introduced in 1987, [1] it was used to perform floating-point arithmetic operations directly in hardware. The coprocessor was designed only to work with the 386SX, rather than the standard 386DX.
The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture. Pre-production samples of the 386 were released to select developers in 1985, while mass production ...
The available Intel Inboard 386/AT has the optional module of 10-MHz 80287 Mathematics Coprocessor for US$495. [3] The Intel Inboard 386/PC comes with 1 Mbyte of 32-bit memory which it has no switches and jumpers. This version was available for US$995. [4] Daughter boards designed for use in the Intel Inboard 386/PC were incompatible with the ...
The 80287 (i287) is the math coprocessor for the Intel 80286 series of microprocessors. Intel's models included variants with specified upper frequency limits ranging from 6 up to 12 MHz. The NMOS version were available 6, 8 and 10 MHz. [10] The available 10 MHz Intel 80287-10 Numerics Coprocessor version was for 250 USD in quantities of 100. [11]
Intel 80386DX CPU with 80387DX math coprocessor. Another coprocessor for the 8086/8088 central processor was the 8089 input/output coprocessor. It used the same programming technique as 8087 for input/output operations, such as transfer of data from memory to a peripheral device, and so reducing the load on the CPU.
Collection of the x87 family of math coprocessors by Intel. A floating-point unit (FPU), numeric processing unit (NPU), [1] colloquially math coprocessor, is a part of a computer system specially designed to carry out operations on floating-point numbers. [2] Typical operations are addition, subtraction, multiplication, division, and square root.
The Intel 486, officially named i486 and also known as 80486, is a microprocessor introduced in 1989. It is a higher-performance follow-up to the Intel 386.It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386.
The 80-bit Intel 8087 math coprocessor ran a factor of 50 faster than the 8/16-bit 8088 CPU that the IBM PC software came with. However, in 1982, the speed-up in floating-point-intensive applications was only a factor of 10 as the initial software developed by Microway and Hauppauge continued to call floating point libraries to do computations ...
