CS48DV2B-CQZ集成电路（IC）的DSP（数字信号处理器）规格书PDF中文资料

CS48DV2B-CQZ属于集成电路（IC）的DSP（数字信号处理器）。由凌云逻辑制造生产的CS48DV2B-CQZDSP（数字信号处理器）数字信号处理器是类似于微处理器或微控制器的器件，但区别在于其内部架构经修改，适用于对连续数据流连续执行以乘法和加法运算为主的算法，而不是以条件逻辑或大量并发进程为主的算法。该器件通常用于诸如音频或视频信号处理等应用。

The new CS48DV2B supports a host of signal processing applications concurrently, including the mass production-ready Dolby Volume solution. See Section 3. for details about firmware concurrency on the CS48DV2B. The target applications for the CS48DV2B DSP are:

— Digital Televisions
