Dear Friends,
We are porting Xfree86 on to a new 32bit RISC processor. We have test
FPGA system running at 2.6 Mega Hertz (Bogomips 0.16) on kernel 2.4.7.
proposed system(ASIC) runs on ~300Mhz.
My main concern is does Xfree86 can be tested on 2.6Mhz FPGA?
What is the minimum clock speed required to run X?
Which is the slowest clock speed system/processor that ran X applications?
Our test system supports 2GB of RAM.
I request your suggestions on feasibility of testing X on the above system.
I've run XFree on a 33 MHz 80386 (Linux). It was slow, but it
worked. It had a whopping 16 MB memory, and a 1 MB VGA video card.
A closer comparison might be a 275 MHz StrongARM processor with
64 MB memory and a 2 MB video device (CyberPro 2000). Painful
unaccelerated, but usable accelerated. Used as my office desktop
for about 2 years, while I was developing on it.
