[sdiy] IC solutions for implementing reconfigurable look up tables?

[David Kantowitz]

Hello Spiros,

Since you're already using a uC, take a look at the Cypress PSoC uC line.
I'm a little more familiar with their really old parts (PSOC1), but the
whole PSoC family is a combination of a uC, reconfigurable logic blocks
(ie. PAL style LUTs internally), an on-chip routing matrix, and the more
typical uC peripheral blocks all in 1 package.  Everything is reconfigured
at run-time.

Configuration has to be done at least once during initialization, but -- at
least with the PSOC1 generation -- it was common to reconfigure the
hardware on the fly to perform different functions as needed (ex. periodic
calibration of external circuits).

I find the cypress website a bit confusing (lots of products lines from
mergers), so try these pages:
    PSoC3 https://www.cypress.com/products/psoc-3    (8051)
    PSoC4 https://www.cypress.com/products/32-bit-arm-cortex-m0-psoc-4
(ARM)
    PSoC1 https://www.cypress.com/products/psoc-1    (proprietary 8-bit cpu)
