在VDSP++的环境下程序已经实现，但是到了CCES下，把中断初始化函数修改了，还是无法正确配置中断，直接返回IIR的中断初始化失败，请问CCES下怎么使用IIR加速器？

代码如下：

/* This code has the TCBS, initialization routines, and the DMA completion ISR for the IIR accelerator */  

#include <services\int\adi_int.h>  

#include "ADDS_21489_EzKit.h"  

#include "IIR_Accelerator.h"  

void Init_IIR(void);  

void ACC_ISR();

                                                                                                                                                      #include "lowpass_200Hz.dat"  

                                                                                                       } ;  

float coeffs_high_pass[];  

volatile int acc_over;  

ad1939_float_data fBlockA;

                                        2|(383<<14)                              // IIRCTL2           = Channel control register, no of biquads = 3, WINDOW SIZE=512  

                              };  

int IIR_TCB_LEFT[13]={  

                                        (int)IIR_TCB_RIGHT+12,          // CP                     = Chain pointer register  

                                        21,                                                  // CC/CL           = Coefficient buffer length register

                                        (int)fBlockA.Rx_L1,                              // II                     = Input data index register  

                                        2|(383<<14)                              // IIRCTL2           = Channel control register, no of biquads = 3, WINDOW SIZE=512  

                              };  

在你的代码里面，你通过

adi_int_InstallHandler(ADI_CID_P0I,(ADI_INT_HANDLER_PTR)ACC_ISR, _NULL ,true);  

把Programmable Interrupt 0 和中断处理函数关联起来了，但是你还需要通过PICRx这个寄存器把Accelerator DMA 的中端映射到Programmable Interrupt 0

这里应该是吧IIR DMA Interrupt映射到Programmable Interrupt 0上吧？

eStatus返回的值为ADI_INT_FAILURE，初始化失败，寄存器PICR_0返回的值为PICR_0：     00001010 01000001 10001000 00111011，至此无法初始化中断，进入不了中断函数void ACC_ISR();
