Abstract
Modularity is a key aspect of system design, particularly in the era of system-on-chip. Field-programmable logic (FPL), particularly with the rapid increase in programmable gate counts, is a natural medium to host run-time modularity, that is, a dynamically-varying ensemble of circuit modules. Prior research has presumed the use of an external processor to manage such an ensemble. In this paper, we consider on-chip management, implemented in the FPL itself, based upon a one-dimensional allocation model. We demonstrate an algorithm for on-chip identification of free FPL resource for modules, and an approach to on-chip rearrangement of modules. The latter includes a proposal for a realistic augmentation to existing FPGA reconfiguration architectures. The work represents a key demonstration of how FPL can be used as a first-order computational resource, rather than just as a slave to the microprocessor.
