Systems and methods for sending data packets between multiple fpga devices

Abstract

Application Specific Integrated Circuit ('ASIC') devices, such as Field Programmable Gate Arrays ('FPGAs'), may be interconnected using serial I/O connections, such as high speed multi-gigabit serial transceiver (“MGT”) connections. For example, serial I/O connections may be employed to interconnect a pair of ASICs to create a high bandwidth, low signal count connection, and in a manner so that any given pair of multiple ASIC devices on a single circuit card may communicate with each other through no more than one serial data communication link connection step. A reconfigurable hardware architecture (“RHA”) may be configured to include a communications infrastructure that uses a high-bandwidth packet router to establish standard communications protocols between multiple interfaces and/or multiple devices that may be present on a single circuit card. Dynamically-sized data packets, sized in accordance with the amount of data ready to be sent, are transferred between the devices and/or interfaces on the card.
