DM6467的HPI速率问题



请问各位DM6467的HPI的速度是多少?谢谢

  • 根据DM6467datasheet 7.18.4 HPI Electrical Data/Timing 以及 Figure 7-59. HPI16 Read Timing (HAS Not Used, Tied High)进行计算。

    计算HSTROBE信号的两个下降沿之间的时间间隔:图中的3+4。

    即HSTBL + HSTBH = 15 + 2Mns

    M =   4/ (CPU clock freauency ) ns 假设使用594 M DSP,M = 6.734ns

    所以总共时间是 15 +2*6.73 = 28.468ns

  • 你好,我想再问下HPI的数据传输速率该怎么算?非常感谢
