一个异步FIFO 为N*64
& h- q4 v3 u5 q$ G0 D/ w/ s
$ H2 c6 @0 |% B# R题干为:

0 N2 _  f$ d+ ~. ~+ A( J5 G" B, ^parameter:

' n% [' k; r+ g3 l! o- p# D9 F' U* G1)Bus's clock is 500Mhz,width is 16 bit.
* z1 K( ]+ l$ R6 S; u
5 c5 [3 {5 Z0 v  {3 K# a% e2)The tipycal data payload packet is 8QW,the ACK packet is 2 DW.

3)The latency from receiver receiving the complete data packet to send out the ACKpacket is 20ns.

# k* X7 G9 g. n! u1 d. }& W4)The throughput of transmitter FIFO's input and output is equaled.

: ~% B- R. G5 LCaculate the optimized FIFO depth N?

怎么算深度N啊???    参数8QW和2 DW是什么意思?  请好心人仔细的指点一下!!!!
; H8 v: T% E% P' j% Y! Y( y  i; V
# T$ m0 L$ F8 i' F) G) N7 }
