AHB is a bus protocol introduced in Advanced Microcontroller Bus Architecture version 2 published by Arm Ltd company. In addition to previous release, it has the following features: large bus-widths (64/128/256/512/1024 bit).
The Advanced eXtensible Interface (AXI) is an on-chip communication bus protocol and is part of the Advanced Microcontroller Bus Architecture specification (AMBA). [1] [2] AXI had been introduced in 2003 with the AMBA3 specification. In 2010, a new revision of AMBA, AMBA4, defined the AXI4, AXI4-Lite and AXI4-Stream protocols.
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of RISC instruction set architectures (ISAs) for computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set.
In 2006, Atmel released microcontrollers based on the 32-bit AVR32 architecture. This was a completely different architecture unrelated to the 8-bit AVR, intended to compete with the ARM-based processors. It had a 32-bit data path, SIMD and DSP instructions, along with other audio- and video-processing features. The instruction set was similar ...

Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus (historically also called a data highway [1] or databus) is a communication system that transfers data between components inside a computer or between computers. [2]
All communication on the bus is under the control of the Bus Controller using commands from the BC to the RTs to receive or transmit. The sequence of words, (the form of the notation is <originator>.<word_type(destination)> and is a notation similar to CSP ), for transfer of data from the BC to a terminal is
Major components on a PICMG 1.3 active backplane Wire-wrapped backplane from a 1960s PDP-8 minicomputer. A backplane or backplane system is a group of electrical connectors in parallel with each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus.
