Extended Kalman Filter 计算速度 (DSP-105) about esp-dsp

[dmitry1945]

Hi @weilian1977 the Process(...) for 13 states Kalman filetr on esp32

takes about ~300k cycles.

For the 13 states implementation the Process(...) takes about ~240k and the UpdateRefMeasurement(...) takes about ~50k.

Hi @dmitry1945， 300k cycles？300×1000/（240×1000000）~ =1.25ms？

[dmitry1945]

Hi @weilian1977 yes. It's about 1.25 mS on esp32. On esp32s3 it's faster, about 1.1 mS.
