In summary: The Power of Simplicity

"Everything should be made as simple as possible, but not simpler." -- Albert Einstein.

The WIZ watchword: Simplicity!

The processor is very simple. It is basically little more than a register file and a few independent arithmetic and logical backend circuits. It has but one function, to copy one register to another. A first year engineering student could understand the complete circuit.

It is very fast. The processor is asynchronous: each register signals when it is done. Thus an instruction "takes as long as it takes". Register-to-register transfers run at a very great speed with no instruction decode and very few levels of logic between them. Being very simple and having nothing on the buses but the registers, bus loads are light and lengths are short. And those operations which are by nature not so fast are implemented in backend logic whose architecture allows parallelism to be maximally exploited.

It has no clock. There is no need for clock or power gating: functions that are not active use absolutely no power.

It is highly customizable.
It is very simple to add custom backend circuits. Any kind of IP block can be embedded in a WIZ, placed behind one or more registers.

It is highly scalable. Any size, speed and functionality WIZ can be created, from a tiny "mote" up to a very large WIZ with supercomputer functionality and speed.

It is highly suited for extreme multi-processing.
It is very easy to put numerous WIZes onto a single chip and numerous such chips into a single system. The WIZ provides a very efficient WIZ-to-WIZ communication capability, and the nature of the design makes it optimal for creating parallelism. Instruction-level parallelism, processor-level parallelism, chip-level parallelism, even multi-chip-level parallelism.

All WIZ hardware is completely compatible and inter-operable. Any WIZ can be interfaced with any other WIZ, with absolute compatibility. Even unusual technologies or process chemistries can be encapsulated behind WIZ registers and thus become absolutely compatible from the WIZ point of view.

All WIZ software is completely compatible and inter-operable. Any ZOZ sequence can run on any WIZ, and within the limits of the particular WIZ's configuration, will run as optimally as is possible.

It is easy to implement in any technology, especially future technologies. The WIZ's circuit is very simple; the gate count is very low; there are almost no internal timing dependencies or potential race conditions; there are no complex interactions between the various parts. The schematic is simple, the place-and-route is simple, the verification is simple. When the next technology comes around (DNA transistors?) the WIZ will be the first to port.

It is easy to test. Because registers and their backend circuits operate independently, there are almost no interactions between them. We can therefore test each device separately, and get very high fault coverage on most devices merely by exercising them with software. No built-in hardware self-test is required or desired -- a software self-test is all that is needed.

It can be supported with a small engineering effort. Because of its simplicity, the WIZ doesn't need to be continuously re-designed every year to add new "features". We don't need to waste a huge amount of engineering resource making each year's model more complex or overcoming the complex problems of the complex interactions between the parts introduced in the last year's model.

It can be made very cheaply. Because it is so simple, there is almost no NRE. Because it small and lacks timing complexity, it will have a very high yield. Because it is asynchronous, it will easily tolerate wide manufacturing variances. Indeed, because of its tremendous redundancy of processors it can tolerate a significant few being taken off-line after failing self-test, and yield therefore becomes almost irrelevant. A complete WIZ chip could sell for a penny.

It can be ubiquitous. Because it can be scaled from very tiny to very large and everything in between, with complete compatibility and interoperability of all hardware and software, the WIZ is the processor for ubiquity. We can have a single type of chip and use it everywhere, from tiny embedded applications to large computational applications, all sharing a single software base. The economies of scale will take over. We won't need separate compilers, operating systems, manufacturing plants, etc. WIZes may still come in many models, but they will be much more similar than they are different.

I rest my case. Now let's do it!!
