Subject: ARM7 CoPro Demo Stuff

The following short graphical program (which originally came from a Solidisk
demo) might be useful for demonstrating the speed (but no use for memory use).

On a standard BBC it takes around 50s to run, but on a fast co-pro it becomes
limited by the VDU drawing speed.

   10MODE0
   20TIME=0
   30CLS 
   40S%=400 
   50VDU29,640;512;
   60MOVE 0,0
   70FOR A=0 TO 126 STEP.25:DRAW S%*SINA,S%*COSA*SIN(A*.95):NEXT 
   80PRINTTIME/100

Hope this is of some use.

Michael
