一种语音压缩编解码芯片中调用过程的实现

Implementation of the Transfer Process in Speech CODEC Vocoder

针对低速率语音压缩算法对处理器系统实时处理复杂运算的性能要求,就程序调用过程的ASIC实现问题进行了对比与分析,进而提出了用层次状态寄存器控制存取算子对存储体交叉访问的方法,并结合运用寄存器窗口传递参数的功能,以及利用空指令硬布线处理流水线冲突的方法,有效地解决了TR600芯片中调用过程存在的主要问题.

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.
