One of the bits in the processor state word see below indicates that the processor is accessing data from the stack.

Intel 8080

Tesla Czechoslovak company MHB Faggin hired Masatoshi Shima from Micoprocesador, 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. Direct memory access request. This page was last edited on 26 Octoberat The processor switches data and address pins into the high impedance state, allowing another device to manipulate the bus.

For 8-bit operations with two operands, the other operand can be either an immediate value, another 8-bit register, nicroprocesador a memory byte addressed by the bit register pair HL.

D0 reading interrupt command.

It also has a bit stack pointer to memory replacing the ‘s internal stackand a bit program counter. The processor also transiently sets here the “processor state”, providing information about what the processor is currently doing: Mifroprocesador on October 23, Write the processor writes to memory or output port.

He finally got the permission to develop microlrocesador six months later. The carry bit can be set or complemented by specific instructions. Intel Intel Intel Direct memory access confirmation.

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. PCs based upon the design and its successors evolved into workstations and servers of 16, 32 and 64 bits, with advanced memory protection, segmentation, and multiprocessing features, blurring the difference between small and large computers [ original research? For more advanced systems, during one phase of its working loop, the processor set its “internal state byte” on the data bus.

IN 05h would put the address h on the bit address bus. Stanley Mazor contributed a couple of instructions to the instruction set.

The address bus has its own 16 pins, and the data bus has 8 pins that are usable without any multiplexing. The A accumulator and the flags together are called the PSW register, or program status word.

Electronic News was a weekly trade newspaper. At Intel, the was followed by the compatible and electrically more elegant It is also used to support the hardware-based step-by step debugging mode. A single layer of metal is used to interconnect the approximately 6, transistors [8] in the design, but the higher resistance polysilicon layer, which required higher voltage for some interconnects, is implemented with transistor gates.



This must be the last connected and first disconnected power source. The integrated circuit uses non-saturated enhancement-load nMOS gates, demanding extra voltages for the load-gate bias.

Please help improve this section by adding citations to reliable sources. It uses the same basic instruction set and register model as the developed by Computer Terminal Corporationeven though it is not source-code compatible nor binary-compatible with its predecessor.

A number of processors compatible with the Intel A were manufactured microprocssador the Eastern Bloc: 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 microproceswdor input port D7 reading data from memory.

The mkcroprocesador gave rise to thewhich was designed as a source compatible although not binary compatible extension of the By adding HL to itself, it is possible to achieve the same result as a bit arithmetical left shift with one instruction. This section possibly contains original research.

The processor has two commands for setting 0 or 1 level on this pin. From Wikipedia, the free encyclopedia.
