嗨,
我有一个设计问题,输入数据是突发性的,输出数据需要是恒定的比特率。
输入clk1(freq) - > 100 Mhz
输出clk 2(频率) - > 64 Mhz
inp_Data - 8位,输出数据 - 1位
输入数据速率 - 8 MBytes / sec,具备以下条件
一个。
爆裂尺寸150 us(长)
湾
突发尺寸100 us(短)
C。
突发之间的间隙可以是2ms到3ms之间的任何值
输出数据速率 - 恒定8 MB /秒(一旦开始读取,您将需要保持数据速率,不允许上溢/下溢)
什么应该是fifo深度?
谢谢,

Hi,
I have a design problem where the input data is bursty and output data needs to be constant bit rate.
Input clk1 (freq) -> 100 Mhz
Output clk 2 (freq) -> 64 Mhz
inp_Data - 8 bit, output data - 1 bit
Input data rate - 8 MBytes / sec with the following conditions
a. Burst size 150 us (long)
b. Burst size 100 us (short)
c. Gap between bursts can be anywhere between 2ms to 3 ms
Output data rate - Constant 8 Mbytes/sec (once you start reading you will need to maintain the data rate, no overflow/underflow allowed)
What should be the fifo depth?
Thanks,
