AN4489 CMSIS-DSP算法的使用

Kinetis products use the ARM® Cortex-M4 processor which supports a single cycle 16.32-bit MAC (DSP function). Using a DSP function such as signal processing, motor control, and data analyze can reduce core resources and enhance core performance. This application note discusses the CMSIS DSP library combined with Freescale MQX RTOS. Included are also the CMSIS and CMSIS DSP library introductions. The application note is based on the CMSIS DSP library version 2.10 using the IAR ARM Workbench Rev.6.21.
