Has anyone out there seen any hardware architecture "optimized for probability processing"? How useful do you think will it be -- especially in which of your products you are working on?

Highly parallel architecture is advantageous in all the applications because they are fast. So more of the probability mathematics can be applied and tested in real time for improved performance.Lyric worked on this for 5 years and won.

Maybe ADI can build lower power and yet high performance DSP that is really sexy. TI I think is their target to beat!

Good report Junko, thanks. Lyric has apparently met with difficulty in finding design wins for their technology. This is not uncommon for something that is "completely different" from the status quo. Applying it to NAND-Flash memory for error correction using Low Density Parity Codes[LDPC]is an appealing mass market application. Why Lyric was not successful here would be an interesting story by itself. It will be interesting to follow where ADI applies Lyric's technology - that is if that information is "allowed" to be made public...,

Lyric's solution has no any advantages over (if is not much worse than) existing pure digital-based LDPC codec being used by companies like LSI and Marvell.

Good point, Gil. Why wouldn't have NAND-Flash guys gone all over Lyrics before ADI snatched them up? I don't know. But definitely something to pursue.

Error Correction of waveforms is conventionally performed by digitizing that waveform (using an ADC) then applying a 'soft decision' error correction algorithm to the quantized waveform levels. It is a cute trick to perform the whole error correction algorithm using an 'analog computer' that relies upon the I-V relationships of the transistors. The big question is whether or not this offers any kind of advantage to the 'digital computer' approach, particularly on sub-micron CMOS.

Analog decoders for codes like Turbo and LDPC codes have been studied for over 10 years in academia and there were some impressive silicon demonstrations, and even few startups were founded but all of them failed eventually.

It seems like FEC decoding is the the most obvious application for this technology, and they're using it for that already. But I wonder what this could do for machine vision?

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
