Abstract
According to one embodiment, a DP accelerator includes one or more execution units (EUs) configured to perform data processing operations in response to an instruction received from a host system coupled over a bus. The DP accelerator includes a security unit (SU) configured to establish and maintain a secure channel with the host system to exchange commands and data associated with the data processing operations. The DP accelerator includes a time unit (TU) coupled to the security unit to provide timestamp services to the security unit, where the time unit includes a clock generator to generate clock signals locally without having to derive the clock signals from an external source. The TU includes a timestamp generator coupled to the clock generator to generate a timestamp based on the clock signals, and a power supply to provide power to the clock generator and the timestamp generator.
