Abstract

The Performance Enhanced Managed Field Programmable Gate Array (PEM-FPGA) is a system component that contains an FPGA, microprocessor, and security features, packaged within a multi-chip module that provides important services, such as dynamic partial reconfiguration, defragmentation, and bitstream decryption. These features allow for the enhanced FPGA to be a secure, sustainable, upgradeable and malleable component for use in a wide variety of defense applications. Innovations include the use of a microprocessor to manage the FPGA, perform full and partial reconfiguration, defragmentation, and security functions. The algorithms running on the microprocessor are implemented in C++, easing the upgrade and maintenance cycle as new techniques become available. Further, the final PEM-FPGA device can be feasibly manufactured such that it results in a drop-in replacement for current COTS FPGAs, eliminating costly test system redesign.

Keywords: FPGA, microprocessor, defragmentation, reconfiguration, partial reconfiguration, memory management, bitstream encryption, anti-tamper
