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 its second version, AMBA 2 in 1999, Arm added AMBA High-performance Bus (AHB) that is a single clock-edge protocol. In 2003, Arm introduced the third generation, AMBA 3, including Advanced eXtensible Interface (AXI) to reach even higher performance interconnect and the Advanced Trace Bus (ATB) as part of the CoreSight on-chip debug and trace ...
The current version (since 1995) by Texas Instruments which bought National Semiconductor is called the 16550D. [ 2 ] The 16550A and newer is pin-compatible with the 16450, but the Microsoft diagnostics program ( MSD ) supplied with MS-DOS 6.x, Windows 9x, Windows Me, and Windows 2000 often report the 16450 chip as an 8250 chip.

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.
Master and Slave Wishbone's interfaces. The Wishbone Bus is an open source hardware computer bus intended to let the parts of an integrated circuit communicate with each other.
MicroBlaze's primary I/O bus, the AXI interconnect, is a system-memory mapped transaction bus with master–slave capability. Older versions of the MicroBlaze used the CoreConnect PLB bus. The majority of vendor-supplied and third-party IP interface to AXI directly (or through an AXI interconnect).
Traditionally, a device has an interrupt line (pin) which it asserts when it wants to signal an interrupt to the host processing environment. This traditional form of interrupt signalling is an out-of-band form of control signalling since it uses a dedicated path to send such control information, separately from the main data path.
