To strengthen its position in high performance multiprocessing embedded systems for military and aerospace applications, Radstone Embedded Computing has just introduced what it claims is the first fully switchable, fully rugged StarFabric switch board.
Called the StarSwitch, it is designed primarily to complement the company's G4DSP-XE StarFabric-enabled multiprocessor host, and operates as both a
StarFabric switch and dual PMC carrier card. It can be used as a 4-port switch
to a multi-slot point-to-point passive backplane or in a chassis-to-chassis
configuration, allowing multiple G4DSP-XE boards to be combined in a range of any-board-to-any-board topologies.
According to Stuart Heptonstall, Product Marketing Manager at Radstone Digital Processing, the StarSwitch has four switched StarFabric ports at the P0 connector and two 64-bit/ 6MHz PMC sites, both of which have all 64 pins of user I/O mapped to P2 or P0 connectors.
The multipurpose board supports VME access to both PMC sites as will as 100 ohm differential pairs to P2 for other high speed I/O. Air- and conduction-cooled, Radstone Levels 1 to 4 StarSwitch's four P0-StarFabric ports can be used as two pairs of bundled links for small, ultra-high performance systems.
Interrupts from the PMC sites are routed either via StarFabric or directly off-board for minimized latency, using an interrupt mapper. StarSwitch's architecture allows traffic on any port at the P0 connector to be routed to either PMC site or switched (re-routed) off-board.
He said any number of StarSwitches can be used together with one or more StarFabric-enabled hosts to form large fabric networks. The board also allows VME access to both VME access to both PMC sites.
The on-board bridges allow isolation of each PMC's traffic from the other and the combination of VME and StarFabric access to PMCs allows separation of the low latency control plane data from bulk data transfers such as such as
direct memory accesses.
