Chelmsford, Mass.Mercury Computer Systems Inc. has developed it fourth-generation switch IC that is compliant with the Serial RapidIO specification 1.2.
Designed to perform multiple switching applications in the embedded, communications, wireless and storage markets, the MC432 is a 64-Gbits/s switch with eight ports of 4X lanes. Each port has four full-duplex serial transceivers.
The MC432 is a serial-based switch that incorporates internal SerDes functionality with 8/10-bit encoding; its previous device was parallel based, according to Mercury's silicon IP systems applications engineer at its Advanced Solutions Business Unit, Charlie Frazer, who cited other enhancements.
"The input packet buffer queue has been significantly increased to allow for more packet buffering. The switch has been enhanced to allow packets through to enable end-to-end flow control within the RapidIO network. The performance metering capabilities have added finer granularity to give system designers more information to fine tune their network for maximum performance," he said.
The MC432 switch IC has input buffering for up to 28 full-size RapidIO packets. Its advanced capabilities include tunable arbitration, which allows users more granularity in setting priorities, giving the designer better control over fabric allocation. It also has adaptive routing, which allows the fabric to dynamically determine the best path for the data packets.
The company also added additional performance metrics to the MC432 to monitor the number of RapidIO link initializations, he said.

It also has standard RapidIO features such as error recovery, priority-based routing, deadlock prevention mechanisms and multicast support.
RapidIO technology is a packet-switched, interconnect and fabric technology. It is designed to enhance the performance of communications processors, host processors, and networking digital signal processors in embedded applications, and allows chip-to-chip and board-to-board communications at performance levels scaling to 10 Gbits/s and beyond.
The MC432 will also be licensed as an IP core to specific customers that may need a RapidIO switch but require a unique process technology for their specific application.
The MC432 is packaged in a 672-FPBGA, measuring 27-mm X 27-mm, and will sample in quantity in the fourth quarter of 2005. It will be priced at $97 each in units of 10,000.
