Active module reconfiguration offers a means for changing design modules in Virtex-II and Virtex-II Pro devices on-the-fly, even while the “base” design continues to operate uninterrupted. This degree of hardware flexibility opens the door to time-multiplexed embedded peripherals, allowing multiple peripherals to share the same physical silicon resources. Device resource utilization, device count, and power consumption, are thereby reduced with a platform that also provides for field upgradeability.

This paper will describe the hardware and software design challenges for building time-multiplexed embedded peripherals, and propose a design methodology to address these challenges. A discussion of lessons learned from a design featuring time-multiplexed encryption/decryption peripherals will be provided, and comparisons will be made to non-reconfigurable embedded systems.
