sru.h

在ADSP-2126x上编写的优化过的IIR滤波器程序（用c和汇编编写）。

//==============================================================================
//
//  SRU.h (c) Copyright 2003 Analog Devices, Inc.  All rights reserved.
//
//  This include file contains a list of macro "defines" to enable the
//  programmer to use symbolic names for ADSP-21262/21266 SRU
//  This is intended to simplify patching in the Signal Routing Unit (SRU)
//
//  28.AUG.2003 - KM - Created
//  26.SEP.2003 - GL - Modified to add the bit names from the manual
//                     This allows programming of the SRU without the macro.
//                     The new definitions begin at line 8989
//                   - Modified comments to be in line with apps header files
//  22.OCT.2003 - Changed DAI_PB*_I_TIMER*_O_PB_ENCODING and DAI_PB*_I_FLAG10_O_PB_ENCODING
//                to DAI_PB*_I_TIMER*_O_ENCODING and DAI_PB*_I_FLAG10_O_ENCODING to agree
//                with HRM.
//  24.OCT.2003 - BM - Bit names from the manual overlap with originally defined bitnames.
//                     added a commented macro definition for those who desire to not use
//                     the SRU(OUT,IN) macro. Uncomment the #define NO_SRU_MACRO if you
//                     desire to use this file without the SRU macro.
//  15.DEC.2003 - KM - Added redundant entries to account for typos in HRM and
//                     compatability with legacy examples: MISCB_x_O = MISCBx_O,
//                     SPORTx_Db_O = SPORTx_DA_O, SPORTx_Db_O = SPORTx_DB_O,
//                     (in HRM Appendix B Group E: DAI_Pxx_O = DAI_PBxx_O),
//                     added FLAGxx_I, TIMERx_I and DAI_INT_xx in Group E
