Shadows for cel animation
We present a semi-automatic method for creating shadow mattes in cel animation. In conventional cel animation, shadows are drawn by hand, in order to provide visual cues about the...

Design Issues and Tradeoffs for Write Buffers
Processors with write-through caches typically require a write buffer to hide the write latency to the next level of memory hierarchy and to reduce write traffic. A write buffer ...
