HaWe brickbench Benchmark Test f. NXT, EV3 & andere

[HaWe]

2 Fragen hierzu:

Ist in C#/Mono
uint
eine 16-bit oder eine 32 bit Zahl ?
(in BCC/gpp C wäre 16-bit Integer int, und 32 bit Integer long)

wie sieht es in C#/Mono mit float (32 bit) und double (64 bit) aus?

[Martin0x5E]

uint: 32-Bit

float: 32-Bit (7 Stellen)
double 64-Bit (15-16 Stellen)

Weil du sagst in gpp ist ein int 16b: in nxtOSEK ist ein int 32 bit und ein short 16 bit

[HaWe]

danke dir!
uint entspricht also "unsigned long",
und float und double entsprechen dann auch den BCC/gpp C Konventionen. Das war wichtig zu wissen.

Übrigens, wenn man "nur" int schreibt, ist in BCC/gpp C int=16bit, aber short kann man auch schreiben, das wäre dann das gleiche (CMIIW).

Wenn nun in C# int =32bit ist - gibt es dann dort ein long mit 64bit? Normalerweise wäre das logisch.

(Ich las mal, auf 8-16bit Prozessoren sei üblicherweise int=16bit, auf 32bit Prozessoren entsprechend int=32bit, long dann jeweils das doppelte, und short die Hälfte, aber nie kleiner 16bit; kA wo ich das her habe....)

Korrekt.

(Ich las mal, auf 8-16bit Prozessoren sei üblicherweise int=16bit, auf 32bit Prozessoren entsprechend int=32bit, long dann jeweils das doppelte, und short die Hälfte, aber nie kleiner 16bit; kA wo ich das her habe....)

C/C++ Schreibt bei der Größe der Datentypen nicht viel vor außer.
char (1 byte) <= short (min 2 byte) <= int <= long (min 4 byte)
Nach dieser Regel kann also int nie kleiner als 16 bit sein stimmt. Üblicherweise ist es so wie du geschrieben hast. (würde mich aber bei c/c++ nie darauf verlassen, einfach mal ein sizeof(int) machen)

[HaWe]

jep, das mit dem sizeof(int) stimmt!

update zu Mono C# Display Zeichen-Funktionen:
http://www.monobrick.dk/forums/topic/be ... #post-4964

I`m not sure that drawing functions are needed on the LegoBrick but I have done its for complete HW brickbench test.
Not so far Anders merged LcdDraw to the firmware and today Ifinally had the time for finish the test.
I hope that Helmut will looking into this message and will update results table on his site.

The full test source can be found here: https://github.com/vladru/MonoBrickBench

The application can be builded in Xamarin studio 5.5.3 with MonoBrick firmware Add-In.
If you will try to open this project in Visual Studio you will catch unsupported format error. Probably this issue caused by using of Xamarin Add-In.
Below the timing (in milliseconds) of steps that was missing in the previous C# test release:
Display_text test (5 loops): 395, 242, 268, 259, 262
Graphics test (5 loops): 475, 180, 182, 172, 199

aktuellste Benchmark-Übersicht wie immer hier: viewtopic.php?f=71&t=8095&start=60#p64772

[HaWe]

bitte bei allen Tests beachten:
wegen eines nan-Bugs wurde der float_math Test abgeändert :

Code: Alles auswählen

#define PI  M_PI


double test_float_math() {

  volatile double s=PI;
  int y;

  for(y=0;y<1000;++y) {
     s*=sqrt(s);
     s=sin(s);
     s=exp(s);
     s*=s;
  }
  return s;
}


es ändern sich die Teil-Benchmark-Laufzeiten hier teilweise nach unten, teilweise nach oben.

Benchmark-Werte wurden inzwischen korrigiert und aktualisiert für:
NXT/NXC, EV3/BCC-C, EV3/Lejos, EV3/C#Mono, EV3-Basic, Arduino Mega, Arduino Due

neue Grafik-Lib ILI9341_due getestet! Link: https://github.com/marekburiak/ILI9341_due

geeignet u.a. für Arduino DUE und ebenfalls UNO und MEGA etc.
Vorteil: volle Ausnutzung des Hardware-SPI-Busses mit schneller Taktung!

Testergebnis mit DUE: Text 15x so schnell wie UTFT, Grafics 13x so schnell wie UTFT !

Brickbench Test für Raspberry Pi (gpp C++)

(getestet mit Raspberry Pi B+, Raspberry Pi 2 Model B, und Raspberry Pi 3 ! )

Geany settings for make/build:
g++ -Wall -I/opt/vc/include -I/opt/vc/include/interface/vmcs_host/linux -I/opt/vc/include/interface/vcos/pthreads -o "%e" "%f" -lshapes -L/opt/vc/lib -lOpenVG -lEGL -pthread -lrt -lwiringPi

Die Benchmark-Ergebnisse schwanken etwas je nach Aktivität von Linux Kernel und gleichzeitig laufenden Hintergrundtasks bzw. Daemons.
Der Pi2 läuft außerdem nicht konstant bei 900 MHz sondern variabel je nach cpu-Last zwischen 600-900 Hz
