GDA Rolls Out PCI Express Controller IP Core with Configurability

9/18/2003 - GDA Technologies, Inc., a fast growing supplier of Intellectual Property (IP) and Electronic Design Services (EDS), announced the GPEX, GDA PCI Express IP core, providing the computing, networking, and communications industries a significant enabler for development of silicon based products supporting PCI Express architecture.

The GPEX is a rich featured and highly flexible core supporting endpoint, root complex, switch, and bridge applications. GPEX's architecture is carefully tailored to optimize link utilization, latency, reliability, power consumption, and silicon footprint for both ASIC and FPGA implementations.

We are committed to providing our customers cost-effective, compliant and interoperable PCI Express IP products," said Prakash Bare, Vice President of IP Business at GDA Technologies Inc. "Our extensive experience in developing high performance IP cores for compute and networking interfaces has played a significant role in creating GPEX which delivers unprecedented performance, configurability, and scalability features to a wide variety of applications.

"Wide availability of PCI Express IP from companies like GDA promotes faster time-tomarket for companies developing PCI Express components, said David Formisano, Ecosystem Initiatives Manager in the Communications Infrastructure Group at Intel. This enables companies to migrate products to PCI Express more rapidly than was possible with previous technology transitions.

The GPEX adheres to the PCI Express 1.0a specifications and is available for both ASIC and FPGA implementations. It supports endpoint, bridge, switch and root complex solutions. It includes MAC, data link and transaction layers. GPEX supports PIPE based PHY architecture and provides a flexible packet oriented user logic interface with an optional DMA controller. GPEX Configurable options include number of lanes (up to 16), number of virtual channels (up to 8), maximum payload size (up to 4K Bytes), and transmit retry/receive buffer size. GPEX provides flow control support for both directions and completely handles PCI Express ordering rules.

GDA will be participating at IDF Fall 2003, September 16-18 at the San Jose Convention Center in San Jose, California. GDA Technologies is an Affiliate Member with the Intel. Communications Alliance, a community of communications and embedded developers and solution providers. For more information, please visit
