SRAM interfacing to XMOS XS1 devices
Posted: Thu Jul 07, 2016 6:14 am
Hello,
I am working on a project wherein I have to design a system wherein I am using the 32 core XS1. Each of the tiles have 256kB SRAM. Now, I am trying to interface additional SRAMs,SDRAMs or even DDR SDRAMs.
For SDRAM, I was going through the forums - http://www.xcore.com/forum/viewtopic.php?f=5&t=105.
It discusses the XShell board and the works on it. The XShell has an SDRAM from Micron. But the link given to the XShell is obsolete. Can I have the link for the said design ? I understand that DDR variants may not be so straight forward as XMOS cannot double clock. So, I will need a glue logic for that interfacing, right ?
Regarding the interfacing of the memory to the XMOS, I believe , the software drivers are available in the Git. Is there any app note explaining the interfacing please ?
