Hello All,
I have questions regarding a project i am currently working on.
I have been assigned to develop an SRAM interface to be able to
Read/Write an SDRAM (Micron 168-pin).And the SRAM should maintain its
own functonality i.e. the SRAM itself can be read/written. Also,
whatever data is read from SDRAM should be stroed in SRAM. I am
following the XAPP134 article and another free IP from
www.cmosexod.com
I know that my SRAM should be able to pass Commands (read/write) to
SDRAM Controller which inturn will trigger the SDRAM for reads/writes
values.
my questions are:
(1) Should my SRAM jsut issue Read/Write command to SDRAM Controller
and then it will do the rest i.e. Read/write from SDRAM.
(2) Should'nt the SRAM output (Q) be a bi-directional since this pin
Q has to be used for SRAM read and also for SDRAM read?
Thanx,
waiting..
