The device implements transistor body bias techniques for forward body bias (FBB) to boost the operating clock frequency for operation at higher OPPs.
Adaptive body bias (ABB) is based on the process corner and the current OPP. This is configured in the EFUSE_CTRL_CUST bit field at the device characterization and is not continuously updated. A dedicated LDO (VBBLDO) is used to produce the voltage bias.
ABB is supported only for MPU, IVAHD, DSPEVE, GPU voltage domains.
