7.1 GB/sec bandwidth 3D rendering engine using the EML technology

We implement a rendering engine which has 7.1 GB/s bandwidth and 11.1 Mpolygon/s drawing speed. It has 3D rendering functions such as double buffering, smooth shading, alpha blending and depth comparison. It can convert 3D primitives into complete pixel data in every 90 ns. A serial access memory permits simultaneous memory access both for rendering operation and for screen refresh operation. The proposed virtual page mapping performs rendering operation without a page miss irrespective of the location of a polygon in the screen. Also, the partial word line activation and the sequential block activation can reduce the power consumption of 64 concurrent memory arrays to only 1.2 W.
