This also means that the directly influenced the ubiquitous bit and bit x86 architectures of today. The various bits of this state word provide additional information for supporting the separate address and memory spaces, interrupts, and direct memory access.

This section possibly contains original research. However, this feature was seldom used. Shortly after the launch of thethe Motorola competing design was introduced, and after that, the MOS Technology derivative of the mifroprocesador The content of other processor registers is not modified.


Faggin hired Masatoshi Shima from Japan, who did the detailed design under his direction, using the design methodology for random logic with silicon gate that Faggin had created for the family. The processor has seven 8-bit registers A, B, C, D, E, H, and Lwhere A is the primary 8-bit accumulator, and the micropricesador six registers can be used as either individual 8-bit registers or as three bit register pairs BC, DE, and HL, referred to as B, D and H in Intel documents depending on the particular instruction.

The data block is copied one byte at a time, and the data movement and looping logic utilizes bit operations. For more advanced systems, during one phase of its working loop, the processor set its “internal state byte” on the data bus.


When the was introduced, computer systems were usually created by computer manufacturers such as Digital Equipment CorporationHewlett Packardor IBM. Please improve it by verifying the claims made and adding inline citations. Mmicroprocesador addition, several early arcade video games were built around the microprocessor, including Space Invadersone of the most popular arcade games ever made.

Although earlier imcroprocesador were used for calculatorscash registerscomputer terminalsindustrial robots[4] micrprocesador other applications, the became one of the first really widespread microprocessors. Every instruction in the has an equivalent instruction in the even though the actual opcodes differ between the two CPUs. D1 reading low level means writing D2 accessing stack probably a separate stack memory space was initially planned D3 doing nothing, has been halted by the HLT instruction D4 writing data to an output port D5 reading the first byte of an executable instruction D6 reading data from an input port D7 reading data from memory.

Discontinued BCD oriented 4-bit By adding HL to itself, it is possible to achieve the same result microprocesadlr a bit arithmetical left shift with one instruction. Federico Fagginthe originator of the architecture in earlyproposed it to Intel’s management and pushed for its implementation. However, the processor load capacity is limited, and even simple computers frequently contained bus amplifiers. Direct memory access request.

The processor also transiently sets here the “processor state”, providing information microprocssador what the processor is currently doing: As with many other 8-bit processors, all instructions are encoded in a single byte including register numbers, but excluding immediate datafor simplicity.

It also has a bit stack pointer to memory replacing the ‘s internal stackand a bit program counter. However, in simple computers it was sometimes used as a single bit output port for various purposes.

The processor has two commands for setting 0 or 1 level on microproesador pin. For simple systems, where the interrupts are not used, it is possible to find cases where this pin is used as an additional single-bit output port the popular RadioRK computer made in the Soviet Unionfor instance.

Statements consisting only of original research should be removed. PCs based upon the design and its successors microproceaador into workstations and servers of 16, 32 and 64 bits, with advanced memory protection, segmentation, and multiprocessing micrporocesador, blurring the difference between small and large computers [ original research? Conditional-branch instructions test the various flag status bits. Switching Mode Circuit Analysis and Design: Intel microprocessors Computer-related introductions in Zilog introduced the Z80which has a compatible machine-language instruction set and initially used the same assembly language as thebut for legal reasons, Zilog developed a syntactically-different microrocesador code compatible alternative assembly language for the Z 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?

It is also used to support the hardware-based step-by step debugging mode.

Intel – Wikipedia

From Wikipedia, the free encyclopedia. Write the processor writes to memory or output port. The Intel is the successor to the Not to be confused with the numbered minor planet Intel. The A accumulator and the flags together are called microprocesafor PSW register, or program status word.

Most 8-bit operations can only be performed on the 8-bit accumulator the A register. He finally got the permission to develop it six months later. Active level indicates that the processor has put the “state word” on the data bus.
