what is an 8088?

Answer 1

A 75 lbs paperweight lol

Answer 2

In the mid-1960s, Intel co-founder Robert Noyce discovered a way to shrink electronic circuitry onto a single silicon chip. Over time, Intel engineers parlayed that technology into a logic device that could retrieve application instructions from semiconductor memory. In 1978, Intel unveiled the 8086, the first commercially viable 16-bit processor. Intel's CPU made it possible for general businesspeople to access processing power that was once the province of a mainframe machine that filled an entire room. When IBM chose the 8-bit version of Intel's CPU, the 8088, for its first desktop PC, it sparked a revolution.
The 8088 is, for all practical purposes, identical to the 8086. The only difference is that it handles its address lines differently than the 8086. This chip was the one that was chosen for the first IBM PC, and like the 8086, it is able to work with the 8087 math coprocessor chip. The prefetch queue of the 8088 is 4 bytes, as opposed to the 8086's 6 bytes.

Answer 3

The Intel 8088 is an Intel microprocessor based on the 8086, with 16-bit registers and an 8-bit external data bus. It can address up to 1 MiB of memory. The 8088 was introduced on July 1, 1979, and was used in the original IBM PC.


Technical Specs
Type: 16-bit multitasking microprocessor; 8-bit bus
Transistors: 25,000
Package: 40-pin CERDIP
Registers: 14 16-bit
Addressing mode (later called Real Mode): Addresses 1MB memory

Answer 4

Others here have explained it well (the 8088 is a low cost 8086, essentially) but one interesting fact is _why_ IBM chose the 8086 and 8088 for the IBM PC. IBM had several reasons for doing so:

1) IBM already had a deal with Intel even though they wanted the 68000 (which went into the Macintosh and the Amiga), they didn't want the 6502 and be seen as a follower or Apple, and the Z80 was old. The Intel chips were the only choice.

2) IBM wanted off-the-shelf parts rather than designing and paying for new parts; with their sales force, it meant high profit and low cost.

3) CP/M already existed (run on Z80 computers) and its existing software and data could be moved to new machines without designing new programs or operating systems.

Someone wrote a file on this a few years ago and said it better than I could. Unfortunately, I can't find it, but it essentially says the same thing; if someone knows it, kindly post it.

Answer 5

The first chip used in PCs was Intel's 8088. This was not, at the time it was chosen, the best available CPU, in fact Intel's own 8086 was more powerful and had been released earlier. The 8088 was chosen for reasons of economics: its 8-bit data bus required less costly motherboards than the 16-bit 8086. Also, at the time that the original PC was designed, most of the interface chips available were intended for use in 8-bit designs. It's ironic, isn't it, that Intel's first production chip was in a way, the "8086SX"? :^) It originally shipped at 4.77 MHz and a "turbo" version was later produced that ran at 8 MHz (Woo.. :^) )

This original chip used what would be considered today to be archaic technology. The 8088 offers performance less than one-thousandth that of a modern processor, showing just how far we have come in 15 years.
