Hello, I am using the Kwikbyte (www.kwikbyte.com) KB9202 development board which is based around the Atmel AT91RM9200 circuit with an ARM920T core running at 180MHz and is said to have 200 MIPS. I am running embedded linux kernel 2.6.11. I have compiled the madlib and the madlld with all optimisations possible for speed but I am not yet happy with the achieved speed, I would like it to go even faster. In madlld there are two structs that are frequently used: mad_synth and mad_frame. I am trying to place them in the embedded 16 kB SRAM memory of the AT91RM9200 to increase speed. From googling I have found that the section attribute could maybe do this so I have created a section in the executable file called .SRAM and placed the structs there - the section is visible by using objdump -h. Now the next tip I have seen is that one then should use a linker script to map the section into the wanted address space. This is where it gets complicated. I cannot make it happen. The linker complains. The 16kB SRAM is addressed at: 0x0020 0000 - 0x0020 4000. I think I maybe am doing this wrong since I am running the program under linux. I have searched and come up with nothing. I would really appreciate if someone can point me into any direction. Jonas Norberg
