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 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.
An all-points bulletin (APB) is an electronic information broadcast sent from one sender to a group of recipients, to rapidly communicate an important message. [1] The technology used to send this broadcast has varied throughout time, and includes teletype , radio, computerized bulletin board systems (CBBS), and the Internet.
Alternating bit protocol (ABP) is a simple network protocol operating at the data link layer (OSI layer 2) [citation needed] that retransmits lost or corrupted messages using FIFO semantics. It can be seen as a special case of a sliding window protocol where a simple timer restricts the order of messages to ensure receivers send messages in ...
The Open Core Protocol (OCP) is a protocol for on-chip subsystem communications. It is an openly licensed, core-centric protocol and defines a bus-independent, configurable interface. OCP International Partnership produces OCP specifications. OCP data transfer models range from simple request-grant handshaking through pipelined request-response ...

Reception to APB has been mixed, with the game holding a 58% average on Metacritic as of February 2016. [40] Initial reviews included PC Gamer giving the title 55/100. [46] and Eurogamer giving APB a 6/10 [44] 1UP awarded APB a grade of D [41] and Destructoid gave a 35/100. [42] Other reviews were higher, with IGN giving a 77/100 [45] and Edge ...
BFMs are sometimes referred to as TVMs or Transaction Verification Models. This is to emphasize that bus operations of the model have been bundled into atomic bus transactions to make it easier to issue and view bus transactions. Visualizations of the bus transactions modeled by TVMs are similar to the output of a protocol analyzer or bus sniffer.
