This project involves a heterogeneous-ISA system based on a BYOC (Bring Your Own Core) framework. This provides a cache coherent, manycore research framework meant to support a variety of ISAs. The ao486 core having a x86 ISA, provides support for legacy code and is one of the few open source CISC ISAs. The initial approach to integration involved connecting BYOC through the Avalon interface. In this project, work is done with the bare interface of ao486 to interface it with BYOC to maintain cache coherency across all cores.
