how is LDS organized in 5870

I can only find the total size of LDS. how is it organized?

How many banks? how is the bank width, 128bit or 32bit?

I think it should be important to get this information before writing a effcient program.

Evergreen LDS has 32-banks, each bank is 32-bit wide. For more information read this :

"For current AMD Evergreen GPUs, local memory is 32 kB, organized into 32 banks; each bank is 4 bytes."

ionel,
Thanks for pointing that out, it should be 1kB per bank. I'll report this to the documentation team.
