What is a 8087 microprocessor?

The Intel 8087, announced in 1980, was the first x87 floating-point coprocessor for the 8086 line of microprocessors. The purpose of the 8087 was to speed up computations for floating-point arithmetic, such as addition, subtraction, multiplication, division, and square root.

What is numeric data processor?

What is Numeric Data processor? 8087 numeric data processor is also popularly called as Math co-processor, Numeric processor extension and Floating point unit due to its faster calculations. To make easier and faster calculations this math coprocessor was first designed by Intel and was paired up with 8086/8088.

What are the data types of 8087?

The standard specifies and the 8087 supports three floating-point data types: Real (single precision), Long Real (double precision) and Tem- porary Real (extended precision). All formats are binary and each has a biased exponent.

What is the role of arithmetic co processor?

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 size of data register in 8087?

80 bit
8087 has eight 80 bit numeric data registers available to the programmer. These registers operate in LIFO (Last in First Out) manner hence they are called as the register stack of 8087. Each register is 80 bits as the data is stored internally in the temporary-real format.

How many pins does 8087 have?

40 pin
How many pins does 8087 have? Explanation: All 8087 models have a 40 pin DIP which is operated in 5V. 11.

What are the types of coprocessors?

There are various types of coprocessors available to perform unique tasks – from I/O interfacing or encryption, string processing, floating-point arithmetic and signal processing.

Which one is not a data type of 8087 processor?

It is used to control the operation of 8087. Explanation: Invalid operation is generated due to stack overflow, stack underflow, indeterminate form as result, or non-number (NAN) as operand. Explanation: A too big result to fit in the format generates this exception.

How many instructions are available in 8087 for the user’s use?

8087 Architecture The numeric extension unit handles all the numeric processor instructions like arithmetic, logical, transcendental, and data transfer instructions. It has 8 register stack, which holds the operands for instructions and their results.

Which pin belongs to the 8087 coprocessor?

RQ/GT1 of 8086. BUSY signal 8087 is connected to TEST pin of 8086.

What do you mean by coprocessors?

Definition of coprocessor : an extra processor in a computer that is designed to perform specialized tasks (such as mathematical calculations)

How 8086 and 8087 works together?

8087 gives an active low request pulse. 8086 completes the current bus cycle and gives the grant pulse and enters the hold state. 8087 uses the shared system bus to perform the data transfer with the memory. 8087 gives the release pulse and returns the system bus back to the microprocessor.

What type of data does the 8087 microprocessor support?

As these instructions are identified by the 8086/8088 processor, it is then specified to the 8087 co-processor to execute further. It supports data of type integer, float, and real types ranging from 2-10 bytes.

What is the 8087 math coprocessor?

To make easier and faster calculations this math coprocessor was first designed by Intel and was paired up with 8086/8088. As these instructions are identified by the 8086/8088 processor, it is then specified to the 8087 co-processor to execute further. It supports data of type integer, float, and real types ranging from 2-10 bytes.

What are the characteristic features of 8087 NDP?

The following are the characteristic features of 8087 NDP: z It can add arithmetic, trigonometric, exponential and logarithmic instructions to the 8086 instruction set for all data types. z 8087 can handle seven data types. These are : 16, 32, 64-bit integers, 32, 64, 80-bit

Is 8086 good for math?

Ans. 8086 is a general purpose microprocessor suitable mostly for data processing applications. But in cases where scientific and other calculation-intensive applications are involved, 8086 fails with its integer arithmetic and four basic math function capabilities. 8087 can process fractional number system and transcendental math functions with
