An embedded debugging/performance monitoring engine for a tile-based 3D graphics SoC development

This paper presents an embedded debugging/ performance monitoring engine (EDPME), which is capable of collect run time characteristics, detect AHB on-chip bus protocol error/inefficiency, and capture on-chip AHB bus traces at various abstraction levels with compression ratio up to 98% for a low cost tile-based 3D graphics SoC development.
