Questions for QuickLogic:

[Willmish]

@JDuchniewicz add more as needed:

We need - I2C communication working, easily portable to Zephyr. I am guessing we will need to use the Wishbone bus?

List of questions for quickLogic about EOS S3:

• [ ] How does the sensor manager work?
• [ ] IS there any documentation how to work with the sensor manager/program it?
• [ ] How does FFE (Flexible Function Engine - Digital Signal Processor) work on EOS S3? Are there any docs around it?
• [ ]

From @JDuchniewicz : How is I2C handled? is it a hardware setup? code in FPGA? (probably hardware regisers etc). How can we access Wishbone and I2C

EDIT: I will be trying to build the toolkit on a pure x86-64 machine (currently doing on an emulated machine on an ARM M1 device)

Building of https://github.com/QuickLogic-Corp/qorc-sdk/tree/master/qf_apps/qf_helloworldhw seems to be broken for FPGA synthesis (install never fully succeeds for me of the envsetup (from https://github.com/QuickLogic-Corp/qorc-sdk/blob/master/envsetup.sh), neither the Docker container: https://github.com/QuickLogic-Corp/quicklogic-fpga-toolchain/tree/71302a5e4b4122976ac9c6e90597146b93083525#3-run-symbiflow-in-a-container , I tried building the yosys fork from scratch (https://github.com/antmicro/yosys/tree/quicklogic-rebased) but there are still issues like this one: https://forum.quicklogic.com/viewtopic.php?t=234

Can we deploy ML model alongside M4 app on the cortex m4, or can we somehow convert it to verilog and synthesize to be flashed on fpga?????

(If we can't deploy the model on the fpga, what else can we use it for?

[Willmish]

• How can we utilise SensiML ? And how dependant is it on qorc-sdk?
• How to program the Sensor Manager? (We are currently reading data from I2C to M4, can we do some preprocessing in the Sensor Manager?
• Have you ever/do you have any tools for synthesizing the ML models to FPGA ? (then the data flow would be : senor over i2c -> FFE -> Sensor Manager -> FPGA -> M4)
• What else can we use the FPGA for ?

[Willmish]

• Sensor Manager/FFE limited instruction set and complicated usage (might not be worth the effort) - useful for reading at fixed intervals the data for very low power applications (with the m4 turned off).
• Data Capture lab (collect data to train the model), can also label the data, then train the model in cloud? and generate a compact model to run on m4.
