The Intel 8085 (" eighty-eighty-five ") is an 8-bit microprocessor produced by Intel and introduced in March 1976. [2] It is the last 8-bit microprocessor developed by Intel. It is software- binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.
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 ...
Intel SDK-85 Kit Assembled Intel SDK-85. The SDK-85 MCS-85 System Design Kit was a single board microcomputer system kit using the Intel 8085 processor, clocked at 3 MHz with a 1.3 μs instruction cycle time. It contained all components required to complete construction of the kit, including LED display, keyboard, resistors, caps, crystal, and ...
Below is the full 8086/8088 instruction set of Intel (81 instructions total). Most if not all [which?] of these instructions are available in 32-bit mode; they just operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
Predecessor (s) Intel 8085. Successor (s) 80186 and 80286 (both of which were introduced in early 1982) Support status. Unsupported. 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 ...
x86 assembly language is the name for the family of assembly languages which provide some level of backward compatibility with CPUs back to the Intel 8008 microprocessor, which was launched in April 1972. [1] [2] It is used to produce object code for the x86 class of processors. Regarded as a programming language, assembly is machine-specific ...
History and description Die of AMD 8088. The 8088 was designed at Intel's laboratory in Haifa, Israel, as were a large number of Intel's processors. 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.
In the x86 computer architecture, HLT (halt) is an assembly language instruction which halts the central processing unit (CPU) until the next external interrupt is fired. [1] Interrupts are signals sent by hardware devices to the CPU alerting it that an event occurred to which it should react. For example, hardware timers send interrupts to the ...
