A system for managing memory resources related to boot, including a memory; a boot configuration circuit, configured to designate one or more memory regions as a first type or a second type, the first type requiring scrubbing before beginning system operation, and the second type permitting scrubbing after beginning system operation; one or more processors, configured to scrub the memory regions of the first type; define a first caching policy of one or more memory regions of the second type; and begin system operation before scrubbing memory regions of the second type.

Memory management

Technologies for an advanced driver assist system (ADAS) with adaptive memory pre-training include a computing device and a safety microcontroller in communication with a serial link and a general-purpose I/O (GPIO) link. Out of reset, the computing device determines whether a full memory training signal is raised via the GPIO link. If not raised, the computing device executes a fast boot path to initialize a memory controller with a pre-trained memory parameter data set and performs margin tests to check the validity of the pre-trained memory parameter data set. If the full memory training signal is raised, the computing device executes a slow boot path to generate the pre-trained memory parameter data set. The safety microcontroller may receive a message requesting full memory training via the serial link and, in response, hold the computing device in reset and raise the full memory training signal. Other embodiments are described and claimed.
