Skybuck's universal code

I have finally figured out what the hell it is I invented :)

It's another universal code:

http://en.wikipedia.org/wiki/Universal_code

I shall name this code:

Skybuck's universal code (pseudo name)

Houppermans's universal code (real name ;))

Data bits:
a,a,a,a,a,a,b,b,b,b,b,c,c,c,c

Marker bits:
0,0,0,0,0,1,0,0,0,0,1,0,0,0,1

Interleaved data and markers bits:

a0a0a0a0a0a1b0b0b0b0b1c0c0c0c1

The above serial information stream contains 3 information fields. The
fields A,B,C in binairy digits (bits)
( a,a,a,a,a,a,b,b,b,b,b,c,c,c,c ).

The information stream is interleaved (=mixed) with "marker" bits. (the
zeros and ones)

0 means another bit follows for the information field.
1 means the last bit has been reached for the information field.

To read field A a piece of software or hardware can use the following logic:

repeat
Read Data_Bit
Read Marker_Bit
until Marker_Bit = 1;

Thereafter the same logic can be used to read the next field.

Bye,
Skybuck.

It segragates different kinds of bits so they don't start fights.

Better to put the ones back there-- ones weigh more and would yield
more traction in the winter.

My favorite math format for embedded uP stuff uses 64 bit variables,
32 bits of signed integer and 32 bits of fraction. That handles any
reasonable physical representations accurately, and the math ops run
fast. Unlike fp, adds and subtracts require no pokey normalizations,
and conversion to/from intger is especially quick (ie, zero
microseconds.)

I wrote a nice little saturating math package for the 68332, which
can't crash or roll over no matter what you do. With a few assembly
macros, it codes sort of like using a calculator. The only thing that
was a real nuisance is the divide. Maybe I'll do a Newton's method
reciprical thing instead, probably would come out faster.

its a great approach.

I like normalised control systems, that way all the numbers tend to be
about 1, and it avoids ill-conditioning, which can be a problem when one
controller handles a variety of different sized systems (eg a motor
controller ranging from 1kW to 1MW). Power systems folks use the
terminology "Per-Unitised" or PU, just to confuse :)

I wrote a nice little saturating math package for the 68332, which
can't crash or roll over no matter what you do. With a few assembly

nice.

In one product I used an interpolated lookup table to perform 1/x. With
33ns multiplies & adds, the routine returned a 16-bit result with < 1
LSB error in 264ns. I had a 3-bit integer, 13-bit fractional
representation. The LUT was 1kb (2 = slope & offset)
