hi guys
i have a black box that its output is like fft algorithm.but im absolutly confused because it use a 8bit pic microcontroller(pic18f252)with this specifications:
sampling pulse is 1Mhz
numbers of data is 256
as i think for this fft u need to a fast micro for lossless data.?????
i think it doesnt lose data because it can detect low altitude voltage between noise.

if its not fft so whats that?if is how its possible?
"thanks in advance"
 

i know fft specification but i want to know that its posibble with this 8bit micro with this speed or not?
 

Under circumstances, a PIC18 can receive a block of 8-Bit data with 1 MS/s, but you should specify the interface. Surely it can't perform the FFT in real time, but that isn't claimed in the specification, I think.
 

hi fvm
i read its datasheet and know it has a hardware multiplier .now can it perform the FFT in real time?or not?
