Software that belongs on the metal.

Real-time keyword spotting on ARM Cortex-M4F. Continuous 16 kHz microphone audio, CMSIS-DSP features, and int8 TensorFlow Lite Micro inference using Zephyr RTOS on a 64 MHz nRF52840.

Embedded-first multi-modal neural network inference for MCU, MPU, and NPU. Float32 and int8 paths, arena allocation, CMSIS-NN / XNNPACK backends, and peer benchmarks against TFLM and TF Lite.

Zero-overhead containers for bare-metal and RTOS targets. Shared cores behind C++ templates and a type-erased C API — no hidden mutexes, no RTTI, no virtual dispatch on the hot path.

FPGA NPU on AMD/Xilinx Zynq-7020 with an 8×8 int8 systolic GEMM array, AXI4-Lite control, and AXI DMA tile transfers. Python host software drives inference and speech-command experiments.
