Architecture: Bus and Device Structure

In this section we examine the basic anatomy of a SoC. Transmitting data consumes energy and causes delay. Basic physical parameters:

Need to use protocols that are tolerant to registers (4P H/S degrades with reciprocal of delay).

But first let's revist the simple hwen/rwen system used in the `socparts' section.
