High-speed scanning parser for scalable collection of statistics and use in preparing data for machine learning

A parser is deployed early in a machine learning pipeline to read raw data and collect useful statistics about the raw data's content to determine which items of raw data exhibit a proxy for feature importance for the machine learning model. The parser operates at high speeds that approach the disk's absolute throughput while utilizing a small memory footprint. Utilization of the parser enables the machine learning pipeline to receive a fraction of the total raw data that would otherwise be available. Several scans through the data are performed, by which proxies for feature importance are indicated and irrelevant features may be discarded and thereby not forwarded to the machine learning pipeline. This reduces the amount of memory and other hardware resources used at the server and also expedites the machine learning process.

Reducing power consumption by selective memory chip hibernation

Power consumption can be reduced by selective memory chip hibernation. For example, a computing device can allocate first data associated with a first processing operation of a user device to a first chip of a dynamic random access memory (DRAM) of the user device. The computing device can allocate second data associated with a second processing operation of the user device to a second chip of the DRAM of the user device. The computing device can determine the first processing operation has been inactive for a predetermined period of time and migrate the first data from the first chip of the DRAM to a storage device of the user device. The computing device can hibernate the first chip of the DRAM while maintaining power to the second chip of the DRAM for continuing to perform the second processing operation.

Techniques for memory access in a reduced power state

Various embodiments are generally directed to techniques for memory access by a computer in a reduced power state, such as during video playback or connected standby. Some embodiments are particularly directed to disabling one or more memory channels during a reduced power state by mapping memory usages during the reduced power state to one of a plurality of memory channels. In one embodiment, for example, one or more low-power mode blocks in a set of functional blocks of a computer may be identified. In some such embodiments, the computer may include a processor, a memory, and first and second memory channels to communicatively couple the processor with the second memory. In many embodiments, usage of the one or more low-power mode blocks in the set of functional blocks may be mapped to a first address range associated with the first memory channel.

Data of a computer system can be secured from malware. During a Primary Operating System (PrimaryOS) run-time, the system determines if the computer system has been compromised and, if so, a Trusted Operating System (TrustedOS) is launched and assumes control of the hardware resources and the software resources of the computer system. The TrustedOS obtains a cryptographic key that is inaccessible to the PrimaryOS. The TrustedOS uses the cryptographic key to disable writing to a first portion of the storage media that includes the first set of logical block addresses. The PrimaryOS can incrementally back-up files to a second set of logical block addresses on a second portion of the storage media. Control of the hardware resources and the software resources is returned to the PrimaryOS.

Memory devices may have an array of elements in two or more dimensions. The memory devices use multiple access lines arranged in a grid to access the memory devices. Memory cells located at intersections of the access lines in the grid. Drivers are used for each access line and configured to transmit a corresponding signal to respective memory cells of the plurality of memory cells via a corresponding access line. The memory devices may use an address scrambler to determine a bit error rate for accessing memory cells and remap an address of a particular memory cell to have a bit error rate below a threshold. In this way, the address scrambler may distribute the bit error rates of multiple accesses of the array.

A system includes a main computing system in which a first user space and a second user space are each allocated exclusively among physical memory of the main computing system. The system also includes a first peripheral component, and a second peripheral component. The first peripheral component receives analog signals from a hardware elements in a first peripheral system and converts them digital signal values in a local memory. A local processor of the first peripheral component is configured via the first user space to write the signal values directly into a first data memory location in the physical memory of second user space using direct memory access. The main computing system uses the signal values to generate output signal values that it writes into a second data memory location of the physical memory allocated to the second user space. A second peripheral component directly accesses the second data memory location to read the output signal values, and writes the output signal values into a local memory. The second peripheral component generates output analog signals based on the output signal values and provides the analog signals to hardware elements of a second peripheral system.
