dear hippo!

i compare the status of boa process in your platform and my arm platform.

the result as follow:

my arm platform:

compare

mem: 157792 bytes

slack: 2876 bytes

shared: 0 bytes

your nios platform:

mem: 286112 bytes

slack: 52682 bytes

shared: 0 bytes

you can see nios plat forum user more memory than arm.

in my arm platform, the linux sourse verision is 2.4

if the application will consume more memory in the 2.6 kernel?

can you help me?

I would expect Nios2&#39;s code efficency will not be as good as ARM&#39;s. Because Nios2 has fewer instruction set.

To reduce memory usage, there are some approaches.

1. rebuild the lib and code with "-Os" flag.

2. in Linux 2.6.12 or later, there is a CONFIG_BASE_SMALL, which will use smaller table size for kernel data.

3. hack the kernel or apps to reduce memory usage and slack.
