摘要
采用高性能价格比的美国德州仪器公司的TMS320C5402数字信号处理器,实现了移动电话车载免持底座系统,系统中存在时间、空间资源冲突。提出消耗多一点时间的方案解决空间资源冲突,以及减少中断次数和用IIR滤波器代替FIR滤波器的方案解决时间资源冲突。
TMS320C5402 digital signal processor of American TI Company has high performance and price ratio. It realized mobile telephone system used on motorcar without holding base. The system had time and space resource confliction. Put forward a scheme that solves the space resource confliction by spending a little more time. And put forward a scheme that solves the time resource conflietion by reducing interrupt times and using IIR filter instead of FIR filter.
