Abstract

While hardware plugins are well suited for processing data with high throughput, software plugins are well suited for implementing complex control functions. A plugin module has been implemented for the FPX that executes software on an embedded soft-core processor. By including this module in an FPX design, it is possible to implement active networking functions on the FPX using both hardware and software. The KCPSM, an 8-bit microcontroller developed by Xilinx Corp., has been embedded into an FPX module. The module includes circuits to be reprogrammed over the network and to execute new programs between the processing of data packerts. A sample application, called the FPX KXPSM Module has been developed that illustrates how easily an application can make use of the hybrid system. This module loads the program memory of the KCPSM from an incoming UDP packet, and executes the new program upon receiving a new incoming UDP packet. The resulting circuit runs at 70MHz and occupies 35% on a Xilinx XCV1000E-7-FG680.
