Multi channel for filter

I told in the initial post that I implemented delay line by connecting rams I.e. o/p of one ram is feed to the second ram. Suppose you need an 8 channel for filter having 6 taps.. So you need 6 rams conmected as mentioned and the depth of each ram would be 8. For a particular channel, we place channel number on the address fields. In. This way our rams behave like delay line. For another channel, we can simpy change the address field on all rams.
