Has anyone any idea where I can get a double precision maths library which will work with the Keil C51 compiler.
"The processor (Cypress CY7C68013) was chosen becaus it has a built in USB2.0 engine." Presumably, that means that it'll be connected to a PC? Could you no send the "raw" data to the PC, have the PC do the number crunching, and perhaps send the results back? Or is it not always connected to a PC?
