ce_lite_nonblockingmode_test_bm#

Overview#

This application demonstrates the non-blocking mode operation of the ZV2118 DSPV-Lite accelerator using the LCE (Lightweight CE) component with a bare-metal OSA backend.

Two bare-metal OSA tasks are created, both performing a 512-point complex F32 FFT (CFFT 512 F32) via LCE_TransformCFFT_F32. 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 BM OSA cooperative scheduler allows the two tasks to interleave while waiting for CE completion.

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.
