3. POLYBLAZE OVERVIEW
The PolyBlaze platform builds off of the MicroBlaze soft processor, leveraging its high level of configurability.Currently,all MicroBlaze configuration options are supported in PolyBlaze, with the exception of cache support, as the current memory hierarchy does not manage coherence between caches.For a Virtex 5LX 110t FPGA,PolyBlaze systems of up to eight cores can be instantiated. Figure 1 provides a high-level overview of the system with key components included. The PolyBlaze platform features a modified version of the MicroBlaze processor, a custom TIC, and a custom memory arbiter.
