I have a lot of constant data, and the total size is almost 200K. 8-bank will be used. However, I remember that a function can only use the constant data in the same bank. Is it right? and If it is true, how should I deal with such a large constant? Thanks a lot
If access speed is not an issue, you could use serial flash ROM, say from Atmel or ST: http://atmel.com/products/SFlash/ http://www.st.com/stonline/products/families/memories/fl_ser/sf_code.htm - mike
