What is an 8086 microprocessor used for

Liula [17]

A sixteen bit microprocessor chip used in early IBM PCs. The Intel 8088 was a version with an eight-bit externaldata bus.

The Intel 8086 was based on the design of the Intel 8080 and Intel 8085 (it was source compatible with the 8080)with a similar register set, but was expanded to 16 bits. The Bus Interface Unit fed the instruction stream to theExecution Unit through a 6 byte prefetch queue, so fetch and execution were concurrent - a primitive form ofpipelining (8086 instructions varied from 1 to 4 bytes).

It featured four 16-bit general registers, which could also be accessed as eight 8-bit registers, and four 16-bit indexregisters (including the stack pointer). The data registers were often used implicitly by instructions, complicatingregister allocation for temporary values. It featured 64K 8-bit I/O (or 32K 16 bit) ports and fixed vectored interrupts.There were also four segment registers that could be set from index registers.

The segment registers allowed the CPU to access 1 meg of memory in an odd way. Rather than just supplyingmissing bytes, as most segmented processors, the 8086 actually shifted the segment registers left 4 bits and addedit to the address. As a result, segments overlapped, and it was possible to have two pointers with the same valuepoint to two different memory locations, or two pointers with different values pointing to the same location. Mostpeople consider this a brain damaged design.

Although this was largely acceptable for assembly language, where control of the segments was complete (it couldeven be useful then), in higher level languages it caused constant confusion (e.g. near/far pointers). Even worse, thismade expanding the address space to more than 1 meg difficult. A later version, the Intel 80386, expanded thedesign to 32 bits, and "fixed" the segmentation, but required extra modes (suppressing the new features) forcompatibility, and retains the awkward architecture. In fact, with the right assembler, code written for the 8008 canstill be run on the most recent Intel 486.

The Intel 80386 added new op codes in a kludgy fashion similar to the Zilog Z80 and Zilog Z280. The Intel 486added full pipelines, and clock doubling (like the Zilog Z280).

So why did IBM chose the 8086 series when most of the alternatives were so much better? Apparently IBM's own engineers wanted to use the Motorola 68000, and it was used later in the forgotten IBM Instruments 9000 Laboratory Computer, but IBM already had rights to manufacture the 8086, in exchange for giving Intel the rights to its bubble memory designs. Apparently IBM was using 8086s in the IBM Displaywriter word processor.

Other factors were the 8-bit Intel 8088 version, which could use existing Intel 8085-type components, and allowed the computer to be based on a modified 8085 design. 68000 components were not widely available, though it could useMotorola 6800 components to an extent.

Hope this helps

I want to take several courses of MIT OCW, and I'm searching for study groups. Is this website the place to find them?

Ymorist [56]

No, this website is not for study groups. It's more of a 'question and answer' website. There is no actual communication on one certain subject. Although I do know a few websites that have worked really well for me,where you can create and participate in study groups;
-studyblue
- studyhall
- getstudyroom
all of these are safe websites that are used by wide variety of students, therefore i'm sure you can find plenty of people interested in learning the same things as you!

Using 20 sentences, as a student, why is it important to identify risk and hazard inside kitchen and home and business propertie

Eduardwww [97]

Answer:

The answer is below

Explanation:

Hazard is something or condition that can cause injury to individuals. If properties are not managed appropriately, the hazard can be inevitable. Every hazard comes with its own risk. And Risk of hazard is the degree to which hazard can affect individuals when exposed to hazards.

Identifying hazards in the surrounding are essential. Also, identifying the risk associated with hazards can't be overemphasized. Hence, the need to identifying both the hazards and the risks associated with it.

There are various reasons it is important to identify risks and hazards inside kitchen and home and business properties. They include the following reasons:

1. It is important to identify hazards in the kitchen, home, and business properties because they may cause injury.

2. Identifying hazards will make us know how to eliminate the hazards

3. When we identify hazards we can easily prevent its future occurrence

4. Identifying hazards in the kitchen such as a bad electric cooker can prevent potential electrical shock

5. When a hazard such as leaking gas is identified, we prevent potential fire outbreak

6. Identifying hazard early is a preventive measure and it is cheaper.

7. Failure to identify hazards in business properties will lead to a great loss of profits.

8. To identify the risk of hazards is the best way to eliminate the hazards.

9. Identifying the risk of hazards can make us anticipate and quickly remove the hazards effectively.

10. It is cheaper to eliminate the risk of hazards when identified than performing repairs after hazards have caused damages.

11. Understanding and identifying the risk of hazard can help save lives, whether kitchen, home, or in business properties.

12. Identifying the risk of hazards, can lead us to have a solution in place against the hazard.
