In addition, several early arcade video games were built around the microprocessor, including Space Invadersone of the most popular arcade games ever made.

The was actually designed for just about any application except a complete computer system. SI, the destination data is stored at ES: Create lists, bibliographies and reviews: Most 8-bit operations can only be performed on the 8-bit accumulator the A register.

Please re-enter recipient e-mail address es. Several factors contributed to its popularity: This must be the last connected and first disconnected power source. The above routine requires the source and the destination block to be in the same segment, therefore DS is copied to ES.

Stoll and Jenny Hernandez. However, the design was expanded to support full bit processing, instead of the fairly limited bit capabilities of the and The various bits of this state word provide additional microprocesseug for supporting the separate address and memory spaces, interrupts, and direct memory access.

The Intel “eighty-eighty” was the second 8-bit microprocessor designed and manufactured by Intel and was released in April Similar Items Related Subjects: Direct memory access request. Direct memory access intsl. The first 8-bit opcode will shift the next 8-bit instruction to an odd byte or a bit instruction to an odd-even byte boundary.


The specific requirements or preferences of your reviewing publisher, classroom teacher, institution or organization should be applied.

Morsethis was a result of a more software-centric approach than in the design of earlier Intel processors the designers had experience working with compiler implementations.

Intel decided to make the logic more complicated, but memory use more efficient. Wikimedia Commons has media related to Intel 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.

Write the processor writes to memory or output port.

It has an extended instruction set that is source-compatible not binary compatible with 808 [4] and also includes some bit instructions to make programming easier. As ofthe is still in production at Lansdale Semiconductors. The and both had dedicated address calculation hardware, saving many cycles, and the also had separate non-multiplexed address and data buses. This design, in turn, later spawned the x86 family of chips, the basis for most CPUs in use today.

Precompiled libraries often come in several versions compiled for different memory models. One of the bits in the processor state word see below indicates that the processor is accessing data from the stack. A faster variant A-1 became available later with clock frequency limit up to 3.


The processor has seven 8-bit registers A, B, C, D, E, H, and Lwhere A is the primary 8-bit accumulator, and ,e other 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 reasons why most memory related instructions were slow mivroprocesseur threefold:.

Intel – Wikipedia

A manufacturer would produce the entire computer, including processor, terminals, and system software such as compilers and operating system. It also has a bit stack pointer to memory replacing the ‘s internal stackand a bit program counter.

In other projects Wikimedia Commons. By adding HL to itself, it is possible to achieve the same result as a bit arithmetical left shift with one instruction. The above routine is a rather cumbersome way to copy blocks of data.

This section microprocessur contains original research. The degree of generality of most registers are much greater than in the intdl Unsourced material may be challenged and removed.

The carry bit can be set or complemented by specific instructions. Although earlier microprocessors were used for calculatorscash registerscomputer terminalsindustrial robots[4] and other applications, the became one of the first really widespread microprocessors.
