Instruction set architecture is distinguished from the microarchitecture, which is the set of processor design techniques used to implement the instruction set.

The result was the RISC ( Reduced Instruction Set Computer ), an architecture which uses a smaller set of instructions.

The acronym VLIW may also refer to Very Long Instruction Word, a CPU instruction set designed to load ( or copy ) a literal value count of inline machine code to the on-chip RAM for higher speed CPU decoding.

Appendix E of Book I: PowerPC User Instruction Set Architecture of PowerPC Architecture Book, Version 2. 02 describes the differences between the POWER and POWER2 instruction set architectures and the version of the PowerPC instruction set architecture implemented by the POWER5.

The AVR Instruction Set is more orthogonal than those of most eight-bit microcontrollers, in particular the 8051 clones and PIC microcontrollers with which AVR competes today.

Design improvements have increased 8051 performance while retaining compatibility with the original MCS 51 instruction set.

Based on the Intel 8051 core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, and low unit cost.

Given " mappings " of input variables into membership functions and truth values, the microcontroller then makes decisions for what action to take, based on a set of " rules ", each of the form:

There is also the Fido 1100, a microcontroller launched in 2007 aimed at predictable embedded control systems such as Industrial Ethernet applications using the 68k / CPU32 instruction set.

Sometimes, for development purposes, the PC is programmed to simulate the entire instruction set of the smartcard's microcontroller to allow smartcard code to be developed more readily.

The Atmel AVR instruction set is the machine language for the Atmel AVR, a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996.

The Mensch Computer is a computer system based on the WDC 65C265 microcontroller ( which implements both the 16-bit instruction set of the W65C816 / 65816 microprocessor, as well as the 8-bit instruction set of the 6502 microprocessor ) and produced by the Western Design Center.

The 8051 microcontroller has two, a primary accumulator and a secondary accumulator, where the second is used by instructions only when multiplying ( MUL AB ) or dividing ( DIV AB ); the former splits the 16-bit result between the two 8-bit accumulators, whereas the latter stores the quotient on the primary accumulator A and the remainder in the secondary accumulator B.

51-FORTH is an implementation of the Forth programming language for the Intel 8051 microcontroller.

* Intel 8051 ( 1980 Harvard architecture microcontroller )

The Intel MCS-51 ( commonly referred to as 8051 ) is a Harvard architecture, single chip microcontroller ( µC ) series which was developed by Intel in 1980 for use in embedded systems .< ref > John Wharton: An Introduction to the Intel MCS-51 < sup > TM </ sup > Single-Chip Microcomputer Family, Application Note AP-69, May 1980, Intel Corporation .</ ref >< ref > John Wharton: Using the Intel MCS-51 < sup > TM </ sup > Boolean Processing Capabilities, Application Note AP-70, May 1980, Intel Corporation .</ ref > Intel's original versions were popular in the 1980s and early 1990s.

In many engineering schools the 8051 microcontroller is used in introductory microcontroller courses.

Among the first of the AVR line was the AT90S8515, which in a 40-pin DIP package has the same pinout as an 8051 microcontroller, including the external multiplexed address and data bus.

Atmel introduced the first 8-bit flash microcontroller in 1993, based on the 8051 core.

The most common variants are LH 2. 2, which uses an Intel 8049 ( MCS-48 ) microcontroller, and usually a 4 kB programme memory, and LH 2. 4, which uses a Siemens 80535 microcontroller ( a variant of Intel's 8051 / MCS-51 architecture ) and 32 kB programme memory based on the 27C256 chip.

The ECU uses an Intel 8051 microcontroller, usually with 16 kB of program memory and usually no advanced diagnostics.
