Advanced Peripheral Bus (APB4 v2.0) AMBA Low Power Interfaces (Q-Channel and P-Channel) AMBA 3 specification defines four buses/interfaces: Advanced eXtensible Interface (AXI3 or AXI v1.0) - widely used on Arm Cortex-A processors including Cortex-A9; Advanced High-performance Bus Lite (AHB-Lite v1.0) Advanced Peripheral Bus (APB3 v1.0)
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.
Slower peripheral cores connect to the OPB, which reduces traffic on the PLB. CoreConnect has bridging capabilities to the competing AMBA bus architecture, allowing reuse of existing SoC-components. IBM makes the CoreConnect bus available as a no-fee, no-royalty architecture to tool-vendors, core IP-companies, and chip-development companies.
Distributed Network Protocol 3 (DNP3) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. Usage in other industries is not common. It was developed for communications between various types of data acquisition and control equipment.
3.0 is the "base" or "core" specification. The AdvancedTCA definition alone defines a Fabric agnostic chassis backplane that can be used with any of the Fabrics defined in the following specifications: 3.1 Ethernet (and Fibre Channel) 3.2 InfiniBand; 3.3 StarFabric; 3.4 PCI Express (and PCI Express Advanced Switching) 3.5 RapidIO
MIL-STD-1553B, which superseded the earlier 1975 specification MIL-STD-1553A, was published in 1978.The basic difference between the 1553A and 1553B revisions is that in the latter, the options are defined rather than being left for the user to define as required.
AMQP is a binary application layer protocol, designed to efficiently support a wide variety of messaging applications and communication patterns. It provides flow controlled, [3] message-oriented communication with message-delivery guarantees such as at-most-once (where each message is delivered once or never), at-least-once (where each message is certain to be delivered, but may do so ...
It includes control and clock signals. RP1 specification also specifies UDPCP - a UDP based reliable communication protocol. A version 2.1 of the reference point 1 interface was published in 2008. [2] RP2 provides a link between the transport and baseband blocks. Version 2.1 of the reference point 2 interface was published in 2008. [3]
