im a newbie in using spartan 3e kit...Is it possible for the spartan
3e kit to store an audio sounds like wav file or mp3 file?
Let size of wav/mp3 file = x
Let available RAM on spartan 3e kit = y
if y >= x then yes, else no
Let size of FLASH = Z
if y >=x or y>= Z then yes, else no ...
I actually, turned a spartan 3e sample kit (the freebee one) into a sample player used in an old car a mate tool on a cross europe car rally.
About 30 samples were stored in 8 bit mono 22K in the flash (several minuites in total if I rememer correctly), and a phase accumulator used to play them at different pitches controlled by some dash mounted switches. A delta-sigma DAC inside the FPGA used an external resistor/cap filter feeding an integrated amp/horn speaker. job done.... /MikeJ
