How does chip of lucky core small RK3588M prevent the power comsumption below setting to you can be optimized in intelligence?
How does chip of lucky core small RK3588M prevent the power comsumption below setting to be able to be optimized in intelligence, it is below a few optimize a method:
Hardware level
- Use the advanced technology that make Cheng: RK3588M uses 8nm to make Cheng technology, itself conduces to reduce power comsumption. In the meantime, its compositive ARM MALI-G610 MP4 GPU and inside the AI of buy quickens NPU, offerring calculate force formidably while, also can reduce power comsumption through efficient framework design.
- Optimize chip framework: RK3588M uses 4 nucleuses Cortex-A76 and the size nucleus framework of 4 nuclear Cortex-A55, big nucleus advocate frequency 2.4GHz, small nucleus advocate frequency 1.8GHz, but the complex degree according to the task is automatic switch core, satisfying function requirement while, reduce power comsumption as far as possible.
- Rational management peripheral: Shut untapped port, wait like HDMI, PCIe, reduce needless power comsumption.
Software level
- Dynamic voltage frequency is adjusted (DVFS): The trends that RK3588M interior configures can effect engine, use DVFS 2.0 technology to come true to come in 0.6V the voltage trends between 1.2V adjusts, according to the laden circumstance of chip real time adjusts voltage and frequency, balance function and power comsumption.
- Optimize drive and kernel: Linux 6.1 kernel increased drive of power source region for RK3588M, can run the power source state of chip better, increase can mechanism of effect adjusting control, wait like government of state of CPU DVFS, low power comsumption, conduce to reduce power comsumption.
- Use low precision operation: RK3588M supports INT4/INT8/INT16/FP16 to mix operation, how to prevent setting in intelligence in, can reduce the power comsumption of processor significantly through using the low precision operation such as INT4 and INT8, assure certain identifying at the same time accuracy rate.
Algorithm and applied level
- Use NPU cent to hold the position of Wu: The NPU of RK3588M has 6TOPS to calculate force, in the AI inference job that how prevents in intelligence, like the person facial identifying, target detection, make full use of NPU will partake the load of CPU and GPU, can reduce integral power comsumption effectively.
- Optimize encode technology: Use AI to feel encode of encode, much ROI, low defer, intelligence to pile up rate control to wait for encode technology, below the premise that assures video quality, reduce data bulk, reduce the power comsumption when chip processes video data.
