您好！
我正在尝试在 MCU F28069M 上实现 CLA_FFT、但无法执行。
首先、该 MCU 可以运行1024点 FFT。
尝试执行以下函数：
__interrupt void
Cla1Task1 (void)
{
__mdebugstop();
CLA_CFFT_run1024Pt();
__mdebugstop();
CLA_CFFT_unpack512Pt();
}这里还有链接器命令文件、我已经设计用于通过 CLA 执行 FFT 和 FIR
_Cla1Prog_Start = _Cla1funcsRunStart;
-heap 0x400
-stack 0x400
// Define a size for the CLA scratchpad area that will be used
// by the CLA compiler for local symbols and temps
// Also force references to the special symbols that mark the
// scratchpad are.
// CLA_SCRATCHPAD_SIZE = 0x100;
--undef_sym=__cla_scratchpad_end
--undef_sym=__cla_scratchpad_start

请引导我是否可以实现。
另外、请帮助确定上述故障以及如何处理。
我使用 ADXL359加速度传感器测量发动机的振动。
由于我每1毫秒对数据进行一次采样、因此我使用 FFT 1024点来实现更高的精度。
但它需要花费更多的计算时间
