I am working on a project in which I am supposed to use the onboard ADC of the Spartan 3E Starter Kit to convert the incoming analog voltage to digital one and then perform some simple arithmetic operations on it like multiplication, addition etc. I have written a VHDL code for the interfacing of pre-amplifier and the ADC and also have VHDL code for the required arithmetic operations. But going through the manual, I came to know that I have to disable a no. of modules while using ADC including Platform Flash PROM. But it was also specified on page no. 29 of the manual that the iMPACT software directly programs the Platform Flash PROM via USB cable. Hence, what I can make out is that there is no way I can use my ADC and PROM(on which code for arithmetic operations will be loaded) simultaneously and hence can't operate on the digital output generated by the onboard ADC. Is there a way out?
