A good compromise between a too intensive restriction of the potential diversity of inter-layer dependencies on the one hand and a too complex signaling of the inter-layer dependencies on the other hand has been found by describing the inter-layer dependencies by way of a first inter-dependency syntax structure indicating inter-dependencies between pairs of different values representable by a base layer-ID and a second inter-dependency syntax structure indicating inter-dependencies between pairs of different values representable by an extension layer-ID, the base layer ID and extension layer ID indexing the layers the portions of the multi-layer data stream are associated with.

One example method includes receiving a write request that includes a data structure version to be written, wherein the data structure version is associated with a unique identifier, storing the data structure version in association with the unique identifier, receiving a read request for a most recent version of the data structure and, when the stored data structure version is not the most recent version of the data structure, examining respective unique identifiers of each of a group of other stored data structure versions to determine which stored data structure version is the most recent. Finally, the example method includes returning the most recent data structure version, notwithstanding that one or more other data structure versions existed at the time that the read request was received.

A data normalization system receives a first string and a second string that are ordered according to an initial string ordering. The data normalization system analyzes, the first string and the second string based on a list of known character sets included in surnames, yielding an analysis, and determines, based on the analysis, that a set of characters in the second string matches a known character set included in the list of known character sets included in surnames. In response to determining that the set of characters in the second string matches a known character set included in the list of known character sets included in surname, the data normalization system orders the first string and the second string according to an updated string ordering.

Embodiments of a system and method for generating a classification model with a cost function having different penalties for false positives and false negatives are described. Embodiments may include perform machine learning operations on known duplicates and known non-duplicates to generate a classification model for classifying structured data items as duplicates or non-duplicates. Each duplicate may represent a pair of structured data items describing a common item; each non-duplicate may represent a pair of structured data items describing different items.

Embodiments may also include evaluating the classification model to determine whether a candidate structured data item is a duplicate or non-duplicate. The classification model may include but is not limited to support vector machines and boosted decision trees.

A method for communicating between a master and a plurality of slaves includes generating a communication frame including generating a slave data frame in each slave. The slave data frame has a data packet including one or more data bytes and at least one gap of variable time length comprising no information in the slave data frame.

The slave data frame is transmitted sequentially where the gap increases for each subsequent slave.

The present invention is a novel RTOS/OS architecture that changes the fundamental way that context switching is performed. In all prior operating system implementations, context switching required disabling of interrupts. This opens the possibility that data can be lost. This novel approach consists of a context switching method in which interrupts are never disabled. Two implementations are presented. In the first implementation, the cost is a negligible amount of memory. In the second, the cost is only a minimal impact on the context switching time. This RTOS/OS architecture requires specialized hardware. Concretely, an advanced interrupt controller that supports nesting and tail chaining of prioritized interrupts is needed (e.g. the Nested Vectored Interrupt Controller (NVIC) found on many ARM processors). The novel RTOS/OS architecture redefines how task synchronization primitives such as semaphores and mutexes are released. Whereas previous architectures directly accessed internal structures, this architecture does so indirectly by saving information in shared buffers or setting flags, and then activating a low priority software interrupt that subsequently interprets this data and performs all context switching logic. The software interrupt must be set as the single lowest priority interrupt in the system.

An apparatus is provided, connectable to a memory and one or more peripherals. The apparatus includes translation request circuitry to receive a translation request from one of the peripherals to translate an input address within an input domain to an output address within an output domain. Signing circuitry generates a signature of at least part of the output address using a private key. Translation response circuitry responds to the translation request by transmitting to the one of the peripherals a translation response, including the output address and the signature. Gateway circuitry receives access requests to the memory. Each of the access requests comprises a desired memory address in the output domain and a signature of the desired memory address. The gateway performs validation of the signature of the desired memory address using the private key and in response to the validation of a given access request failing, performs an error action.
