The 8087 coprocessor has several key registers that facilitate its operations, primarily focused on floating-point arithmetic. These include the Floating-Point Stack (ST(0) to ST(7)), which holds up to eight floating-point numbers, and the Control Register (C0), which manages the rounding mode and precision settings. Additionally, it has the Status Word (SW) that provides information about the state of the coprocessor and any exceptions encountered, and the Instruction Pointer (IP) that points to the next instruction to be executed. Other registers include the Data Segment (DS) for data access and the Temporary Register (TOS) for intermediate calculations.

What is the working of 8087 NDP microprocessor?
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.
What is 7220 plus 867?

Why implement 8086 processor to 8087 processor?
The 8086/8088 is the general purpose processor. The 8087 is the math co-processor for the 8086/8088.
What are the release dates for The Young and the Restless - 1973 1-8087?
The Young and the Restless - 1973 1-8087 was released on: USA: 7 March 2005
Why 8086micro processors are called co- procossers?
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.
What are different data types used in 8087 programming?
Abstract,etc
What is the advantage of 8087?
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.
What is meant by co processor configuraiton in 8086?
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.
What are the types of microprocessor register?
Microprocessor consists of different types of registers. They special purpose registers, general purpose registers, address registers, floating point registers and constant registers.
What is clock frequency of 8087?
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.
What are floor registers used for?
Floor registers are not the registers you find checking out at a grocery store. Floor registers are the cover from the heating vent in a home or business.
What are the Types and functions of registers?
A computer has address registers and data registers. The address registers usually keeps the computer informed about where certain data stores are kept.
