The voltage is provided by the power supply. Power is supplied from a lithium-ion battery for CEM/PCH/PTEL, and from a 5V 2A AC adapter for DEM/PDEL/VTE.
The voltage is controlled by the Syscon and is automatically adjusted according to the system clock frequency.
Categorizes
The system also categorizes voltages into four types, called VDD.
| Name | Description | Who settings this |
|---|---|---|
| DD1/VDD | General Purpose Processor. IFTU, DMAC, Internal Bus, Camera Bus, SPM 32KiB/128KiB. | scePowerSetSysClockFrequency (SysTimer)
scePowerSetDmac5ClockFrequency scePowerSetBusClockFrequency scePowerSetCameraBusClockFrequency |
| DD2/VDDA | ARM Core, L2 Cache. | scePowerSetArmClockFrequency |
| DD3/VDDC | Codec Engine, AVC Decoder. | scePowerSetVipClockFrequency
scePowerSetVeneziaClockFrequency |
| DD4/VDDG | GPU Core. | scePowerSetGpuClockFrequencyInternal
scePowerSetGpuXbarClockFrequency scePowerSetCompatClockFrequency |
The voltage is automatically adjusted by the system, but you can also set the voltage manually by calling sceSysconCtrlVoltageForDriver (but be careful, because Set*ClockFrequency always adjusts the voltage when called).
Average Voltage
The average voltage are measured with the clock fixed for each VDD.
