Interestingly enough, and perhaps BW> obvious in retrospect, I often found hardware designers to be very BW> comfortable with dataflow computations. dataflow computers was known at least from 60's as possible alternative to Neumann architecture with its bottleneck of only one operation executed each time. they are very natural for chip designers because real internal processor structure is dataflow, and for external users (assembler programmers) Neumann architecture is emulated -- Best regards, Bulat mailto:bulatz@HotPOP.com
