Petach Tikva, Israel, November 04, 2013 --(PR.com)-- DoGav Systems, a leading provider of software and hardware consultancy specializing in Freescale's PowerQUICC™ communications processors, today announced the new addition to its range of microcode products: Parallel Redundancy Protocol (PRP) for Freescale’s MPC83xx PowerQUICC™ II Pro, and MPC8555E/8560 PowerQUICC™ III processors built on Power Architecture™ technology.
PRP, a data communication protocol standardized as IEC 62439-3 Clause 4, allows systems to overcome any single network failure without affecting the data transmission. It is perfectly suited for Industrial Ethernet applications since it is independent of the protocols used and provides seamless failover. Under PRP, each network node has two Ethernet ports attached to two different local area networks of arbitrary, but similar topology.
Layer 2 network redundancy is achieved by sending two copies of the same frame over two independent LANs. As long as one LAN is operational, the destination always receives one frame. This protocol provides a zero-time recovery and allows to check the redundancy continuously to detect lurking failures.
This microcode module is self contained and require no additional hardware or modification to existing hardware. It is also fully forward-proof as it can be easily updated and/or customized. It supports 10/100/1000 Mbps rates.
“The PRP microcode module is the latest addition to our growing list of microcode products, and a further illustration of our commitment to the development of microcode for Freescale's PowerQUICC™ communications processors,” said David Gabbay, President and CEO of DoGav Systems. “We are very excited about this product that was developed as a direct result of market demand and we are already in discussion with customers seeking to deploy it in their systems.”
The PowerQUICC™ II Pro and the PowerQUICC™ III families incorporate two main components: an embedded core processor built on Power Architecture technology and a communications processor module -- a dedicated RISC engine optimized for handling communications tasks - known as QUICC Engine™.
The QUICC Engine™ technology supports a wide range of protocols, and it operates independently from the core processor. It has it own instruction set and can be programmed via “microcode” by only a handful of companies carefully selected and licensed by Freescale. This presents the opportunity for implementing higher levels of networking protocols and/or introducing new protocols, resulting in considerable application complexity offload and an increase in the overall performance.
The PRP module is available now.
