Experimental Noize

Preprocessor V1.6 posted today for all platforms, some internal changes to better support the upcoming full release of GooeyCore Graphical Development Environment for the FXCore.

Updated to V0,7, link in top post also updated. Many internal things cleaned up, added a directory of blocks under "Help" so users can see what is available in the libraries.

If you installed V0.5 or V0.6 you just need to copy over the executable from the zip file, no other files changed.

Updated to V0,6, link in top post also updated. Cleaned up file menu, "save" now remembers file name and saves it, keyboard shortcuts now work, added Ctrl+T as a toggle shortcut to toggle between "Device" and "Net" modes so both show Ctrl+T on the menu now. If you insta...

This is an early version alpha release so there are a number of things not yet working but the core functions do work and can be used.

That is very interesting info, we had not optimized the design for convolution but it appears a small one is doable. At 32K it should do over 200 MACIDs bases on the number you gave so 2 FXCores in series each doing 200 MACs should leave some space for pre and post processing of the signal in each F...

Will be interesting to see the results of your test.

FXCores can be run serially, output of one into the input of another. So depending on target function, costs, speed requirements, etc. this may be a solution.

400 MACs is a huge number. I doubt the delay read on FXCore would be the limiting factor (internal memory is SRAM so very fast R/W), it would probably be the multiply in each MAC. Multiplies are "slow" as there are many gates to go through. My guess is the FXCore would not work in this cas...

16-bit linear, not floating point.

V2.4.2 of the assembler for all supported platforms posted 13 March 2023 - Rewrite of the equation solver, much better at determining if "-" means subtraction or unary subtraction/negation. Better handling of parentheses. Some equations with errors that may have been ignored by old equatio...

Assuming you are running at 48K sample rate which is a sample period of 20.8uS, 800uS is 38.48 sample periods so call it 39 sample periods. AK4556 has a group delay of 18 samples for the ADC and 21 for the DAC which is 39 sample periods. So basically the delay is due to the CODEC. An AK4558 can be c...
