Fundimentally, it's a 8-way vector unit. But rather than the vectors being math ops, they're memory blocks. In addition to the normal block-moves, it also has pattern fill, overlay, barrel shifting, and merging. Setup time should be 3 cycles, and once running can do very large units of memory control in a limited time. In my design the GPU had no direct access to RAM, only to a small internal fifo buffer, which the blitter would continuously feed in and out. This kept the GPU itself very small. > -- > Timothy Normand Miller > http://www.cse.ohio-state.edu/~millerti > Open Graphics Project _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
