Abstract

Various examples disclosed herein relate to trimming of system elements to prepare the elements for execution of boot code and application code. In an example embodiment, a system is provided. The system includes system control circuitry, direct memory access (DMA) circuitry, and processing circuitry. The system control circuitry is configured to instruct the DMA circuitry to obtain trim data from memory upon detecting that a first group of system elements has reached an initialized state. The DMA circuitry obtains the trim data and writes it to trim registers. The system control circuitry supplies the trim data to a second group of system elements to bring them to an operational level, then instructs the processing circuitry to execute boot code.
