What is the major difference between 8088 and 8086 microprocessor?
The only difference between an 8088 microprocessor and an 8086 microprocessor is the BIU. In the 8088, the BIU data bus path is 8 bits wide versus the 8086’s 16-bit data bus. Another difference is that the 8088 instruction queue is four bytes long instead of six.
What is the use of 8087?
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 makes 8088 a 16-bit microprocessor?
The Intel 8088 has a clock speed from 5-10 MHz, with 16-bit registers, a 20-bit address bus, a 16-bit external data bus, and supports 1 mb of memory. The Intel 8088 also supports the Intel 8087 numeric co-processor that enables it to recognize and process floating point data and instructions.
What are the different 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.
How many types of basic multiprocessor configurations are there?
There are typically 3 types of configurations: Master / Slave Configuration, Loosely Coupled Configuration, and Symmetric Configuration.
What are different parts for 8086 architecture?
The internal architecture of Intel 8086 is divided into 2 units: The Bus Interface Unit (BIU), and The Execution Unit (EU).
What are the flags in 8086 processor?
8086 has 16-bit flag register, and there are 9 valid flag bits….Status Flags.
| Flag Bit | Function |
|---|---|
| CY | This is carry bit. If some operations are generating carry after the operation this flag is set to 1 |
| O | The overflow flag is set to 1 when the result of a signed operation is too large to fit. |
What is the working of flag?
The Flag register is a Special Purpose Register. Depending upon the value of result after any arithmetic and logical operation the flag bits become set (1) or reset (0). In 8085 microprocessor, flag register consists of 8 bits and only 5 of them are useful.
