An 8.69 Mvertices/s 278 Mpixels/s tile-based 3d graphics full pipeline with embedded performance counting module, real-time bus tracer and protocol checker for consumer electronics

Abstract

A tiled-based 3D graphics IP is designed to support OpenGL ES 1.0. The test chip runs at 139MHz and achieves 8.69 Mvertices/s and 278 Mpixels/s with its die size as 15.7 mm 2 . The IP includes embedded circuitry to monitor run time 3DG characteristics, detect bus protocol error and inefficiency, and capture bus trace at various abstraction levels with compression ratio up to 98%.
