ce_lite_nonblockingmode_test_freertos#
Overview#
This application demonstrates the non-blocking mode operation of the ZV2118 DSPV-Lite accelerator using the LCE (Lightweight CE) component with a FreeRTOS OSA backend.
Two FreeRTOS tasks are created, both performing a 32-point complex F16 FFT
(CFFT 32 F16) via LCE_TransformCFFT_F16. The CE command buffer is initialized with
kCE_CmdModeOneNonBlocking, so the CM33 does not busy-wait for ZV2118 to finish each
command. Instead, the LCE component handles synchronization internally, and the FreeRTOS
preemptive scheduler allows the two tasks to run concurrently while waiting for CE
completion, providing better CPU utilization than the bare-metal variant.
Each task validates its result by computing the normalized squared error between the computed output and the reference output, and reports pass/fail over the serial console.
