Hi! I am working on an ml403 board (virtex4 with ppc core). I am sucessfully using Linux 2.4 and 2.6. I have done a few performance tests with networking, applications...
In the Virtex 4 is it possible to use BRAM(which are 10 times faster then the normal RAM)... I would like to connect this BRAMS in a special address area... Questions: 1.1. Is it possible to write a linker script, that places heavly used Code(or importend Interrupt Routines...) of the kernel in my special Adress Area(on the BRAM)? Has anyone already written such a Linker script? 1.2. Or do I have to tell the bootloader to copy the special marked (how?) heavly used Code in this special Area? Has anyone done such a thing? 2. Is there a way to tell the Kernel to place heavily used Application Code or Data automatically in my special Adress Area? Has anyone worked on such a thing? Nice greetings Robert
