Abstract: Systems, methods, and apparatuses for implementing input/output extensions for trust domains are described. In one example, a hardware processor includes a hardware processor core comprising a trust domain manager to manage one or more hardware isolated virtual machines as a respective trust domain with a region of protected memory, and input/output memory management unit (IOMMU) circuitry coupled between the hardware processor core and an input/output device, wherein the IOMMU circuitry is to, for a request from the input/output device for a direct memory access of a protected memory of a trust domain, allow the direct memory access in response to a field in the request being set to indicate the input/output device is in a trusted computing base of the trust domain.

Abstract: In one embodiment, a design tool for designing a system on chip (SoC) includes hardware mapping logic to automatically generate a channel mapping for a path between a first intellectual property (IP) logic of the SoC and a second IP logic of the SoC. The hardware mapping logic, based at least in part on user input of a source channel associated with the first IP logic, a sink channel associated with the second IP logic and at least one derivation parameter, is to generate the channel mapping according to one of a plurality of derivation algorithms. Other embodiments are described and claimed.

Abstract: In one embodiment, a design tool for designing a system on chip (SoC) includes hardware logic to generate one or more configuration files for a fabric of a SoC to be designed by the design tool. This logic is configured, based at least in part on user input, to generate the one or more configuration files, according to at least one of: automatic derivation of all parameters of the fabric, according to a first user selection; manual input by a user of at least some parameters of the fabric and automatic derivation of at least other parameters of the fabric, according to a second user selection; and manual input by the user of the all parameters of the fabric, according to a third user selection. Other embodiments are described and claimed.

Abstract: Techniques for handling unaligned data in a computing system are described herein. The techniques may include receiving data from an input/output (I/O) device, through an I/O interface. The data may be padded by adding values to the data at the I/O interface if the data is unaligned with respect to that computing system such that a consumer of the data associated with the I/O device ignores the added values.

Abstract: In an example, a control system may include a system-on-a-chip (SoC), including one processor for real-time operation to manage devices in the control system, and another processor configured to execute auxiliary functions such as a user interface for the control system. The first core and second core may share memory such as dynamic random access memory (DRAM), and may also share an uncore fabric configured to communicatively couple the processors to one or more peripheral devices. The first core may require a guaranteed quality of service (QoS) to memory and/or peripherals. The uncore fabric may be divided into a first “real-time” virtual channel designated for traffic from the first processor, and a second “auxiliary” virtual channel designated for traffic from the second processor. The uncore fabric may apply a suitable selection or weighting algorithm to the virtual channels to guarantee the QoS.

Abstract: A method and an apparatus are described for regulating the concentration of metal ions in an electrolytic fluid, which is used for the deposition of metal with insoluble anodes and additionally contains compounds of an electrochemically reversible redox system. With the oxidized form of said system, metal is dissolved in an ion generator 1, traversed by the fluid, so that these compounds are thereby reduced. For the deposition of metal, the dissolved metal ions on the item to be treated are reduced. The compounds of the redox system in the reduced form are oxidized again on the insoluble anodes in the electroplating system 13. In order to keep the concentration of the metal ions in the electrolytic fluid constant, at least a portion of the electrolytic fluid, contained in the electroplating system, is conducted through one or a plurality of electrolytic auxiliary cells 6.
