DEAR AMIGA: I am sure that every one will be interested in this. The problem I have discovered with the amiga is the amount of time the CPU is allowed to have the bus in highres mode (640x200). That is ONLY DURRING THE BLANKING PERIOSDS OF THE SCREEN. This is due to the DMA needing the bus. This really does upset me when I realize that the processor wich is executing my floating point routines, is only active about 70% of the time. The draws might be fast for a graphics application but the majority of the time my program is going to be calculating where the endpoints to be placed. Honestly this makes my application slower and does not solve the problem of "graphics_power". The partial solution is to add another block of memory above 512K. But (HERE IS THE CATCH) I can't load my program where I want to. That is AMIGA-DOS's JOB... So :::: If I get memory above 512K to speed my application Will I be able to LOAD my program into this memory????? As of now I see no solution. It would run faster above 512K but unfortunatly I have no control over where my program is placed. AMIGA CAN YOU ENLIGHTEN ME PLEASE!!!!!!!!
