The 8087 is a numeric coprocessor that enhances the computational power of a system by offloading complex floating-point calculations from the main CPU. This improves the performance of mathematical operations, especially in scientific and engineering applications.
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
In a mechanical advantage system, the force is multiplied by the factor of the mechanical advantage. The formula for mechanical advantage is MA = output force / input force. This means the force can be multiplied by the mechanical advantage value.
Time can be used to measure mechanical advantage by comparing the time taken to perform a task with and without a mechanical advantage device. If a mechanical advantage device reduces the time required to complete a task, it indicates that the device has increased the efficiency of the task, thereby providing mechanical advantage.
The amount by which a machine multiplies an input force is called mechanical advantage. It is calculated by dividing the output force by the input force.

8087
The 8086/8088 is the general purpose processor. The 8087 is the math co-processor for the 8086/8088.
The Young and the Restless - 1973 1-8087 was released on: USA: 7 March 2005
The 8086 is not a co-processor. The 8087 is. The 8087 is intended to be coupled to an 8086/8088 to do math co-processing.
Abstract,etc
The co-processor on an 8086/8088 is the 8087 math co-processor. The motherboard will be designed with an extra socket for the 8087, which then integrates with the 8086/8088 to make a single unified processor.
The Intel 8087 math coprocessor typically operates at clock frequencies of 5 MHz, 6 MHz, and 10 MHz, depending on the specific model and the system it's integrated with. It was designed to work in conjunction with the Intel 8086 and 8088 microprocessors, enhancing their mathematical computation capabilities. The 8087 facilitates floating-point arithmetic and other complex calculations, significantly improving performance for applications that require such processing.
The 8087 and 8089 coprocessors serve different purposes in computing. The 8087 is a math coprocessor designed specifically for performing floating-point arithmetic operations, enhancing the computational capabilities of the 8086/8088 CPUs. In contrast, the 8089 is an I/O coprocessor that manages input/output tasks and facilitates communication between the CPU and peripheral devices. While both enhance system performance, they address distinct aspects of processing.
The 8087 Math CoProcessor can work with two data formats: temporary real and packed decimal. Each data instruction, whether real or decimal, can be up to 80 bits long.
The 8087 Numeric Data Processor is an adjunct to the 8086/8088 microprocessor, that gives the 8086/8088 floating point capability and 8 more registers. The 8087 integrates itself with the 8086/8088 in such a way that the pair actually becomes one processor, appearing to have the extra instructions and registers to start with.Since it was an optional add-on to the system, many run-time libraries would detect whether or not the 8087 was present, and either use it or emulate it.This separation of functionality into two chips was maintained in the product line up until the 80386DX and 80486, although the NDP was called something else (such as the 80287, and 80387) at which point the NDP became a permanent part of the instruction set.
The phone number of the Ettrick-Matoaca Library is: 804-526-8087.
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.
