Driven by the transition in processor-based systems and associated chipsets from PCI to PCI Express as the main peripheral bus
, the Expresso family of OXPCIe952, OXPCIe954, OXPCIe958, OXPCIe840 targets the PC peripheral, industrial control, point of sale, server, communications and embedded systems markets with 2, 4, and 8 serial port options plus a standalone parallel port device.
The free controller features deterministic operation, very fast I/O response (less than 100 nanoseconds) and supports the advanced peripheral bus
For additional performance and flexibility the PowerPC is bridged to the Xilinx Spartan-3E with a high bandwidth On-chip Peripheral Bus
(OPB) Bus Master controller, facilitating a true, dual processor system capable of implementing nearly any desired expansion interface.
A NAND Flash Controller and a full suite of Serial I/O ports, including UART, IIC, SPI and 32-bit external peripheral bus
are additional key connectivity capabilities of the 405EXr.
The new Xilinx VLYNQ interface provides a bridge to the CoreConnect On-chip Peripheral Bus
(OPB) available on Xilinx FPGAs.
Offloading CPU-intensive software subroutines to hardware in a DRC Reconfigurable Processor Unit (RPU) makes applications run many times faster than ordinary solutions connected to a peripheral bus
