CPCI 720 Series
The CPCI 720 series is an enhanced version of the popular CPCI 800 adapter, featuring improved architecture and support for wire-speed performance with small packets. The CPCI 720 series is available as a single or dual port HSSI, DS3, or E3 WAN adapter for demanding video and multimedia networking applications.
The CPCI 720 is based on a 32-bit 33 MHz PCI controller that supports bus mastering at a burst rate of 132 MB per second. The main components of the CPCI 720 include the Intel i960HD66 RISC processor, the PCI controller, and two DXI HDLC controllers. The i960 processor manages packet flow between the DXI controller, packet RAM and host RAM. The i960 can act as a PCI bus master with direct access to host RAM, or it can initiate DMA transfers between packet RAM and host buffers via the PCI controller. The VLSI DXI controller module supports both HDLC and transparent modes of operation at speeds of up to 52 Mbps per port. Dual 8/16 KB FIFOs are connected directly to the DXI HDLC controller for both transmit and receive channels to minimize packet transfer latencies.
