What was the first IBM PC processor?
The Intel 8088.
Which one launch first 8088 or 8086?
1978 - 8086 1979 - 8088 First IBM PC used 8088. I think later low end IBM PC's used 8086.
How many Hz did the 8088 processor run at?
The original 8088 processor had a maximum clock frequency of 5 MHz. As implemented in the original IBM PC, it ran at 4.77 MHz. There were variations of the 8088 that could run at 8 MHz.
How many bits in 8088?
The Intel 8088 microprocessor was a variant of the Intel 8086 and was introduced on July 1, 1979. It had an 8-bit external data bus instead of the 16-bit bus of the 8086. The 16-bit registers and the one megabyte address range were unchanged, however. The original IBM PC was based on the 8088.
What is the function of the PC register in the 8086 CPU?
There is no PC register in the 8086/8088. It is called the IP register by Intel and it stands for the Instruction Pointer. It contains the address of the current/next instruction to be executed.
How much ram could the 8088-processor access?
8088 processor accessed 1MB
how much is a PC?
A pc can cost $5
What was Intel's first microprocessor?
The 4004 was Intel's first microprocessor and the world's first single chip microprocessor. For the first PC as we know it (the 1981 IBM PC), it was the 8088, following with 80286, 80386, 80486 and then the Pentium line.
8088 and 8086 were introduced by?
The 8086/8088 family of microprocessors was introduced by Intel.
Why did the 8088 is come out after 8086?
Because that's what Intel chose to do. The 8086 was released in 1978. The 8088 was released in 1979, and it was the same 16 bit processor core, but running on a 8, instead of a 16, bit bus, making it more tenable in low end, cheap, systems, such as the IBM PC.
What was the word length of Intel's 8088 microprocessor which powered the original IBM pc?
The Intel 8088 is generally considered to be a 16-bit processor (most registers were 16 bit registers), and therefore had a 16-bit word length, although its external data bus was only 8 bits wide.
Do 8086 have in built clock?
The 8086/8088 has a clock oscillator circuit. You provide a crystal, and it will generate a clock signal that controls the speed of the processor. In that respect, it has a clock.The 8086/8088, however, does not have a time of day or date clock. You can build a software entity that keeps day/date time using interrupts from a divider off of the clock oscillator but, that is not the same thing as a non-volatile clock chip such as provided in the PC, but which is not part of the 8086/8088.
