HI, all 1.problem I use DS5250 chip for an encryption device. Recently, I added "SHA-1" C source code in my project. But the total code size is greater than 64KB. 2.question The "code banking in LX51" is best solution? environment CPU : 8051 Memory : external 128KB SRAM cf. contiguous mode 16M program Regard.
What optimisation level are you currently using?
Thank you for your reply. Because of a time difference,my reply was late. Really I don't know "optimization level". Could you tell me that meaning? I appreciate your help. Regards.

thanks. My project optimisation level is '8(default)'. Much higher level required?
Thank you, Andy. I set Optiomization level 9(do not support to 11 level in my KEIL compiler). I would have got 63KB code size file. Now, I read documents about "code banking". In the future, my project will be updated. So I think "code banking" techniques is required finally. Regards.
So I think "code banking" techniques is required finally. Not if you're using contiguous mode it isn't. Not needing code banking is what contiguous mode is all about.
