Re: Memory addressing and CMAC
@Dennis thanks for the great info, hope to see more about CMAC and memory collision in the next part of this series.

Re: Memory addressing and CMAC
Netcrawl,

The tradeoff you refer to between collisions and shrinking address-space through hashing will be addressed more in the next three parts of this sub-series within neuronics.

In the end, I hope to present an analog CMAC implementation concept, though the present description is from a purely digital implementation using ordinary memory. The collisions cause us to start thinking about CMAC output in terms of signal to noise ratio. It is as though purely digital computing, with its accuracy down to the bits themselves, is being displaced by some other more analog concepts. And indeed, that is the case. CMAC can be envisioned as how to make digital computers do analog computing.

Memory addressing and CMAC
@Dennis Great post about addressing distributed memory, hardware implementation in CMAC is still difficult to achieve, CMAC's conceptual memeory need a huge space to address te encoded input. Hash algorithm are applied to reduce the space to more reasonable size but these approacxh has some serious drawbacks- collision.

Previously we looked at the electronics and sensors involved in data acquisition systems (DASs). Now we look at what to do with the raw ADC data once it is acquired.
This is a tutorial presentation of principles of instrumentation that is typically multi-channel, medium to high resolution (12 to 20 bits) and relatively slow - slower than oscilloscopes in sample rate
Continuing the chat from last time, we turn now to a circuit-related topic, that of current waveforms. The typical converter input waveform is shown with a static (dc) component and a ripple (ac) component
Semiconductor companies have now had fully-differential amplifiers in their product lines for a few years, though these amplifiers have been in leading-edge electronics for decades. These diff-amps are differential not only at their input but also at their output, doubling output range.
