Die of AMD 8088. The 8088 was designed at Intel's laboratory in Haifa, Israel, as were a large number of Intel's processors. [9] The 8088 was targeted at economical systems by allowing the use of an eight-bit data path and eight-bit support and peripheral chips; complex circuit boards were still fairly cumbersome and expensive when it was released.
The XSAVE instruction set extensions are designed to save/restore CPU extended state (typically for the purpose of context switching) in a manner that can be extended to cover new instruction set extensions without the OS context-switching code needing to understand the specifics of the new extensions.
The Intel 8080 ("eighty-eighty") is the second 8-bit microprocessor designed and manufactured by Intel. It first appeared in April 1974 and is an extended and enhanced variant of the earlier 8008 design, although without binary compatibility. [3] The initial specified clock rate or frequency limit was 2 MHz, with common instructions using 4, 5 ...
NEC V60. The NEC V20 is a microprocessor that was designed and produced by NEC. It is both pin compatible and object-code compatible with the Intel 8088, with an instruction set architecture (ISA) similar to that of the Intel 80188 with some extensions. [2] The V20 was introduced in March 1984. [1][2]
IBM PC compatible. CPU. Intel 8088 at 4.77 MHz (early models) Intel 8088 at 4.77 MHz or 7.16 MHz. Memory. 256 KB RAM (stock) The Leading Edge Model D is an IBM clone first released by Leading Edge Hardware in July 1985. It was initially priced at $1,495 and configured with dual 5.25" floppy drives, 256 KB of RAM, and a monochrome monitor.
The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979, [5] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM PC design.
For example, where Intel uses the mnemonics MOV, MVI, LDA, STA, LXI, LDAX, STAX, LHLD, and SHLD for various data transfer instructions, the Z80 assembly language uses the mnemonic LD for all of them. A similar case is the NEC V20 and V30 CPUs, enhanced copies of the Intel 8086 and 8088, respectively. Like Zilog with the Z80, NEC invented new ...
The 8080 System Design Kit (SDK-80) of 1975 provided a training and prototype vehicle for evaluation of the Intel 8080 microcomputer system (MCS-80), clocked at 2.048 MHz. (The basic 8080 instruction cycle time was 1.95 μs, which was four clock cycles.) The SDK-80 allowed interface to an existing application or custom interface development.
