Intel decided to make the logic more complicated, but memory use more efficient. The E-mail message field is required. By using this site, you agree to the Terms of Use and Privacy Policy.

The first 8-bit mivroprocesseur will shift the next 8-bit instruction to an odd byte or a bit instruction to an odd-even byte boundary.

You may have already requested this item. At most one of the operands can be in memory, but this memory operand can also be the destinationwhile the other operand, the sourcemicroprocesweur be either register or immediate. The provides dedicated instructions for copying strings of bytes. A ceramic D variant.

Some of the control pins, which carry essential signals for all external operations, have more than one function depending upon whether the device is operated microprocesseue min or max mode. D0 reading interrupt command.


From Wikipedia, the free encyclopedia. It was an attempt to draw attention from the less-delayed and bit processors of other manufacturers such as MotorolaZilogand National Semiconductor and at the same time to counter the threat ontel the Zilog Z80 designed by former Intel employeeswhich became very successful.

The programming lr and instruction set is loosely based on the in order to make this possible. The processor switches data and address pins into the high impedance micropricesseur, allowing another device to manipulate the bus. Add a review and share your thoughts with other readers. Due to the regular encoding of the MOV instruction using a quarter of available opcode spacethere are redundant codes to copy a register into itself MOV B,Bfor instancewhich were of little use, except for delays.

Stanley Mazor contributed a couple of instructions to the instruction set. The was actually designed for just about any application except a complete computer system. Write the processor writes to memory or output port. The degree of generality of most registers are much greater than in the or This design, in turn, later spawned the x86 family of chips, the basis for most CPUs in use today. This routine will operate correctly if interrupted, because the program counter will continue to point to the REP instruction until the block copy is completed.

The Intel inel the standard math coprocessor for the and microproxesseur, operating on bit numbers. Please improve it by verifying the claims made and adding micrlprocesseur citations.

This address space is addressed by means of internal memory “segmentation”.

Some instructions also enable the HL register pair to be used as a limited bit accumulator, and a pseudo-register M can be used almost anywhere that any other register can be used, referring to the memory address pointed to by the HL pair. The and gave rise to thewhich was designed as a source compatible although not binary compatible extension of the Stoll and Jenny Hernandez.

Intel 8080

While perfectly sensible for the assembly programmer, this makes register allocation for compilers more complicated compared to more orthogonal bit and bit processors of the time such as the PDPVAX, etc. This must be the first power source connected and the last disconnected, otherwise the processor will be damaged.


A single memory location can also often be used as both source and destination which, among other factors, further contributes to a code density comparable to and often better than most eight-bit machines at the time.

The above routine requires the source and the destination block to be in the same segment, therefore DS is copied to ES. The E-mail Address es you entered is are not in a valid format. The size of chips has grown so that the size and power of large x86 chips is not much different from high end architecture chips [ original research?

There are also eight one-byte call instructions RST for subroutines located at the fixed addresses 00h, 08h, 10h, Concepts and realities, Intel Preview Special Issue: However, formatting rules can vary widely between applications and fields of interest or study.
