Realboard-continue to challenge arm high performance software simulation limit

After a new round of optimization, the core arm instruction set execution speed of realboard is much higher than that of Android emulator (qemu). On the same platform (2g, 1g memory ), the VGA code stream is tested by the h264 full-speed software decoding test (because qemu only supports ARM9. therefore, you have to select the arm9-version decoder for comparison ). The latest results show that the realboard speed is nearly twice that of qemu.

 

Android emulator running result (sdk2.1, executed through ADB shell ):

Framewidth = 640
Frame Height = 480
Frame number = 500
Decodetime = 46526068 us

Framerate = 10.75fps

Although it is only one step away from qemu's 2-fold acceleration, the realboard is still not able to meet the current situation, and its original design is to be used as a real-time simulation platform with high computing complexity in multimedia, we hope that the execution speed of the realboard will be three to five times faster than that of the qemu in the next day, which is close to 50% of the execution efficiency (1 GHz) of the PC host machine ).
