AIC3254 PurePath blocks to support logical branching?

Hello.

May I ask for more standard building blocks for the PurePath studio to support logical branching of the code? For example:

minimum / maximum value of N inputs

minimum / maximum absolute value of N inputs

mux with data input (currently one may convert data to coefficient and control the mux with a coefficient, but that is inconvenient and muddles the design)

counter block to implement timers (count up only, count up / down, with set / reset inputs)

Some of the blocks may be implemented using existing blocks, but I doubt that the resulting code will be time and memory efficient. For example I tried to implement maximum of two function using 1x CompareCD, 3x Splitter, 2x Scale, 1x Negate, 1x AddCtoD and 1x AddData blocks. One can imagine how cluttered the schematic will be with couple of maximas.

I did not manage to build a hierarchical component as I did not find the Component Publisher program. Where may I obtain the Component Publisher?

Limiting the miniDSP programming to PurePath seriously limits what can be achieved with the chip and we are seriously considering to choose another product with clear documentation and more versatile development tools. We would consider it a great pity as the AIC3254 chip fits our needs well if only we can teach it what we need.

Thanks, Ondra

    Hi, Ondra,

    Sorry, we have not implemented this as it is outside the normal application usage of these devices.
