can open a large array as 1024bytes for CY7C68013 ?

since my topic use CY7C68013+AD7934+EEPROM as directly convert an analog signal to digital and send back to PC, but for the sampling rate of 10kHz, i want to have a buffer for me to save those data...and i have tried a lot of ways for opening a large array in KeilC...
but most of the time it's not access...
can someone else tell me how to create it...
and i would wonder ask... can i allocate it @ fx2reg.h? and how to finish it up?

one of my unsuccess way...
