So... I've made a little "LoRa" (CSSS) beacon demo with #ULX3S and #PipelineC ! Ramp Nco ("SF6") -> Sine / Cosine NCO's => 2nd Order Delta sigma DAC => digital iq mixer -> output #sdr #fpga #rf #csss #lora #dsp #dac #sigmadelta #alldigitaltx

Nice... We did something similar for #PipelineC and ended up doing the FFT in hardware too! @pipelinec_hdl

Want a fast, simple, and small integer FFT implementation geared for 32-bit (ARM + RISC-V) processors? I have largely rewritten one of the more popular fix_fft implementations and got the OK by most recent maintainers to put it under the MIT license. github.com/cnlohr/fix32_f…



1/4 as many RV32I @risc_v cores for same or better performance. Threads share #PipelineC auto pipelined ~15 stage kernel() hardware function to offload shader compute. CPU is now bottleneck for moving data around from RAM to pipeline and back. #FPGA #HDL #RTL #graphics #riscv

Use #PipelineC to listen to FM #radio with an #FPGA #SDR! Huge thanks to @DutraCGI and @Darkknight512 for making this first version a great learning process. And @deepwavedigital for the fantastic #hardware platform and workplace <3 fosstodon.org/@pipelinec/112… #hdl #hls #asic

Four RV32I @risc_v cores totaling ~333M IPS do work with a 480p frame buffer 🤓. 20 threads, ~software rendering, but focus isn't on CPU core, next up: experiments with custom accelerator pipelines to offload compute 😏 #PipelineC #FPGA #HDL #RTL #graphics #riscv


So... I made a blog... The first official post is about the #PipelineC #NCO I was developing last week! @ico_TC paulo-d2000.github.io/en-us/2023/10/… #FPGA #SDR #DSP
