droidBooster benchmark results on Renesas Phone Demonstrator: speedup of x6.98!
|
05 October 2010
FlexyCore and Renesas Design France (RDF), a subsidiary of Renesas Electronics, a premier supplier of advanced semiconductor solutions, are collaborating together to evaluate the benefits of droidBooster technology on a Renesas phone demonstrator.
This demonstrator is based on a SH-Mobile platform that has a cortex A8 ARM core running at 600 MHz and runs Android Eclair 2.1 without JIT (dynamic compiler).
After realizing the porting of droidBooster for the Renesas phone demonstrator, FlexyCore used CaffeineMark™ benchmark, designed by Pendragon Software, to measure the Java code performance. We measured the score of CaffeineMark on Eclair 2.1 with and without the use of droidBooster. We used droidBooster version 0.9.9189 with our generic ARM backend without any specific platform optimizations.
The table below presents the results: droidBooster provides a speedup of x6.98 !
| Renesas phone demonstrator | CaffeineMark score |
| Android Eclair 2.1 with droidBooster | 7544 |
| Android Eclair 2.1 without JIT | 1078 |
To compare the Android performance reached on the phone demonstrator, the table below presents some results we get on some other platforms. Using droidBooster, the Renesas phone demonstrator provides x6.14 times more performance than the Eclair 2.1 platform (HTC Desire), and x1.69 times faster than NexusOne running FroYo 2.2. Remember that the Renesas phone demonstrator runs at 600MHz and NexusOne and HTC Desire at 1GHz, so the impact on the energy consumption will also be largely in favor of Renesas phone demonstrator.
| Phone | System | Platform | CPU | Frequency | CaffeineMark score |
| HTC Desire | Android Eclair 2.1 with droidBooster | QSD8250 | Scorpion | 1 GHz | 11978 |
| Renesas phone demonstrator | Android Eclair 2.1 with droidBooster | SH-Mobile | Cortex A8 | 600 MHz | 7544 |
| HTC Legend | Android Eclair 2.1 with droidBooster | MSM7227 | ARM1136-EJS | 600 MHz | 4666 |
| NexusOne | Android FroYo 2.2 | QSD8250 | Scorpion | 1 GHz | 4446 |
| HTC Desire | Android Eclair 2.1 | QSD8250 | Scorpion | 1 GHz | 1228 |
| NexusOne | Android Eclair 2.1 | QSD8250 | Scorpion | 1 GHz | 1128 |
| Renesas phone demonstrator | Android Eclair 2.1 | SH-Mobile | Cortex A8 | 600 MHz | 1078 |
| HTC Legend | Android Eclair 2.1 | MSM7227 | ARM1136-EJS | 600 MHz | 730 |
