Abstract
Embodiments herein describe a reconfigurable integrated circuit (IC) where data can be retained in memory when performing a partial reconfiguration. Partial reconfiguration includes reconfiguring programmable logic in the IC while certain functions of the IC remain operational or active. In one embodiment, the reconfigurable IC includes control logic for saving or retaining data in the IC during a partial reconfiguration. That is, rather than clearing the memory elements, the user can specify that the memory blocks containing certain data should be retained while the other memory blocks can be cleared. In this manner, the data can be retained in the IC during a partial reconfiguration which saves time, power, and cost. Once partial reconfiguration is complete, the newly configured programmable logic can retrieve and process the saved data from the on-chip memory.
