What are the basic features of 80486?
Intel 80486, also known as i486 or just 486, is the fourth-generation generation Intel x86 microprocessor. The 80486 was capable of over 40 million instructions per second (MIPS) and offered roughly twice the performance of the 386. It featured an 8K cache for storing recent instructions.
What are the additions made in 80186 after 8086?
80186 and 80188 Processors After Intel produced the 8086 and 8088 chips, it created versions of these chips with some of the required support components integrated within the processor.
What are the features of 8086 microprocessor?
Features of 8086 It was the first 16-bit processor having 16-bit ALU, 16-bit registers, internal data bus, and 16-bit external data bus resulting in faster processing. It uses two stages of pipelining, i.e. Fetch Stage and Execute Stage, which improves performance.
What are the features of Pentium processor?
Features of Pentium Processor are as follows:
- 64 bit data bus.
- 8 bytes of data information can be transferred to and from memory in a single bus cycle.
- Supports burst read and burst write back cycles.
- Supports pipelining.
- Instruction cache.
- 8 KB of dedicated instruction cache.
In which mode does 80286 have features of MMU and protection mechanism?
In real address mode, the 80286 is object code compatible with 8086. In protected virtual address mode, it is source code compatible with 8086.
What is the difference between 80186 & 80188 microprocessor?
The Intel 80188 microprocessor was a variant of the Intel 80186. The 80188 had an 8-bit external data bus instead of the 16-bit bus of the 80186; this made it less expensive to connect to peripherals. The 16-bit registers and the one megabyte address range were unchanged, however.
What is the difference between 8086 and 80186?
8086 has an operating frequency of 5 to 10 MHz. 80186 has an operating frequency of 8 MHz to 10 MHz. The operation codes 63H and 64H are not available in 8086. 80186 accepts the operation code 63H and 64H and these codes will present an interrupt of byte-6.
What are the features of microprocessor?
Features of Microprocessor Low Cost – Due to integrated circuit technology microprocessors are available at very low cost. It will reduce the cost of a computer system. High Speed – Due to the technology involved in it, the microprocessor can work at very high speed. It can execute millions of instructions per second.
What is the feature is not about 8086 microprocessor?
Which of the following is not a Features of 8086? D. It has 512 vectored interrupts. Explanation: It has 256 vectored interrupts is true Features of 8086.
What are the advantages of Pentium processor?
(i) Pentium has 64 bit data bus which allows higher speed of data transfer to it. (ii) The data transfer speed of Pentium is twice as fast as a processor with 32- bit data bus.
What does the Pentium microprocessor do?
The original Pentium model includes two processors on one chip that contains 3.1 million transistors. The Pentium Pro, released in 1995, was designed for PC servers and workstation that needed to serve multiple users or needed the speed required for graphics-intensive applications.
What type of motherboard is used by 80286 processors?
The Intel 80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bit microprocessor that was introduced on February 1, 1982….Intel 80286.
