    I am trying to get a quadcopter flying using the Pixhawk controller (Cortex M4 running NuttX RTOS) and I am using the Simulink Pixhawk PSP to implement a custom controller. Our controller uses neural...
  • In NEON, have the three instructions( VCLS, VCLZ, VCNT), are they all count sign bit?
    In NEON spec: VCLS (Vector Count Leading Sign bits) counts the number of consecutive bits following the topmost bit, that are the same as the topmost bit, in each element in a vector, and places the results...
