measure memory bandwidth on Atom processor

sorry if I might ask my question in a wrong place.I try to measure the memory bandwidth on the Atom processor. The frequency of the front end bus is 533MHz and I use DDR2-666. In theory, the memory bandwidth is limited by the front end bus and the maximum memory bandwidth is 4.16GB/s. The memory bandwidth I measured withSiSoftware Sandra and my own C program (with memcpy in GNU C library) is 2.6GB/s. I don't understand why there is such difference. The bandwidth I measured is the real bandwidth in the system?Best,Da

CE4100 18.26903 SDK build error

I just installed the SDK, and when I do "make menuconfig" I got compilation error in lxdialog/dialog.h : curses.h No such file or directory.

Little poking around and figured out the build process requires ncurses-5.6, which is still tarred under package/devtools.

My expectation was it should be untarred automatically when I am doing a first time build. I tries deconfig it did not work.

Any suggestions on how to get past this?


problem with stepping into functions

Hi All,

I am using Intel Application Software Development Tool Suite for Intel Atom Processor. I have built my project with ICC with -debug and -O0 options. And after following the given procedure i am able to get the executable running on the debugger. But the problem is, while debugging I am not able to step into any function or open any file other than the file with main funciton. Only the C file with main() is detected as source file!!

What can be the reason behind this??

Thanks in advance
