memory-to-memory transfer
7.For the real time performance need of the Low Speed Speech Compress Algorithm and the ASIC implement of the transfer process between programs, the design is put forward in the paper, in which state registers control the cross access between operator and memory, register windows are used for the parameters transfer, and the technique of hardware controlling is used to avoid pipeline conflict, so that the main problems of the transfer process in TR600 are solved effectively.
9.For different application fields and software/hardware configuration, MPEG-2/4 AAC can provide different coding/decoding profiles. Different coding tool in different profile requires different computational complexity and memory size. So MPEG-2/4 AAC can provide all-round solutions to the storage and transfer of Hi-Fi audio.
10.The application of Cyclic Redundancy Check (CRC) in serial communication is introduced in this paper.If the system memory is limited and data stream is large,the method of allowing data to transfer and at the same time to check is proposed,and the principle of data stream block transferring is also discussed in detail.It solves the real time and reliability of transferring data stream for serial communication in micro-control system based on MCU.
