Handling of graphics is also very fast (point, rectangle, text output etc.) and list or matrix manipulation Here a program to draw the ULAM spiral ```EXPORT Ulam BEGIN LOCAL a,b,xy:={128,63}, n:=1, m:=.9, d:={{1,0}, {0,-1}, {-1,0}, {0,1}}; RECT(); WHILE n<60000 DO FOR a FROM 1 TO 4 DO m:=m+.5; FOR b FROM 1 TO m DO IF isprime(n) THEN PIXON_P(xy(1),xy(2),0);END; xy:=xy+d(a); n:=n+1; END; END; END; FREEZE; END; ``` 34 sec for 60.000 loops (and prime test) Edited: 24 Feb 2013, 8:00 p.m. Re: HP-39gII speed - Thomas Klemm - 02-24-2013 From Xerxes' Calculator Benchmark: ``` Calculator Speed Benchmark using the N-Queens Problem ------------------------------------------------------- - 1:30 HP-50G UserRPL - 1:29 TI-Nspire Formula / List / TI-84+ Keypad / OS 3.0 - 1:13 TI-Nspire Formula / List / TI-84+ Keypad / OS 1.2 - 1:10 TI-Nspire Formula / List / TI-84+ Keypad / OS 1.3 - 1:07 HP-50G UserRPL / Fast Mode x1.3 (75->203 MHz) - 8.3 TI-Nspire CAS Formula / List / OS 1.2 - 7.5 TI-Nspire Formula / List / OS 1.2 - 4.2 TI-Nspire CAS Formula / List / OS 1.3 - 3.9 TI-Nspire Formula / List / OS 1.3 ------------------------------------------------------- - 2.3 TI-Nspire CAS Formula / List / OS 3.0 - 2.1 TI-Nspire Formula / List / OS 3.0 - 1.32 HP-39GII Formula / List ------------------------------------------------------- - 0.895 HP-50G HP Pascal Studio 2.1 / Cross Compiler - 0.622 HP-50G HP Pascal Studio 2.1 / Cross Compiler / Fast Mode x1.5 (75->203 MHz) - 0.243 HP-50G HPLua 0.4 / Bytecode - 0.0504 TI-Nspire CAS Lua / Bytecode / OS 3.1 - 0.0445 TI-Nspire CX CAS Lua / Bytecode / OS 3.1 - 0.00613 HP-50G HPGCC 3.0 / RegVars / Cross Compiler / Slow Mode x12.7 (75->6.0 MHz) - 0.00524 HP-50G Assembly / ARM9 @ 6.0 MHz / Slow Mode x13 - 0.000484 HP-50G HPGCC 3.0 / RegVars / Cross Compiler - 0.000404 HP-50G Assembly / ARM9 @ 75 MHz - 0.000192 HP-50G HPGCC 3.0 / RegVars / Cross Compiler / Fast Mode x2.5 (75->192 MHz) - 0.000150 HP-50G Assembly / ARM9 @ 192 MHz / Fast Mode x2.7 ``` This is the inverse time (s-1): ```0.4348 TI-Nspire CAS 0.4762 TI-Nspire 0.7576 HP-39GII ``` Now the TI-Nspire doesn't look so bad anymore. Or even much better when considering Lua: ``` 19.84 TI-Nspire CAS 22.47 TI-Nspire CX CAS ``` Quote: In any case, difficult to find a model for the time as fast as the HP-39gII that is surely the public calculator fastest in the world. ```,___, {O,o} |)__) -”-”- O RLY? ``` Kind regards Thomas Edited: 24 Feb 2013, 5:58 p.m.
