Hello friends I'm working on a SOC, which has 8051 core & a generic DSP embedded on to it. I already have application code ready with me. Now our vendor has shipped new version of SOC, which supports banking. My major problem is banking. How may i break my existing application in to diffrent banks. For this SOC common area is fixed & it is 32K. Total memory is 48K. So i'm left with 16K which i have to utilise for switching banks. My application will reside on a NAND Flash. In the old SOC i was using L51_Bank.a51.
What is variable banking? Can i use it here? I refered keil website, i didn't get any solution. Does anybody give me some suggestion? Thank you in advance.
Using such an old version is partly your problem. Mentor E8051EW and Evatronix R8051XC are both IP cores that support code banking.
For Mentor see in the current version 8.05 of C51: C:\Keil\C51\Examples\M8051EW\APNT_171.htm
