Abstract: Embodiments relate to a system with multiple erasure codes, and selecting and encoding for a write file with one of the codes to mitigate costs associated with storage recovery. The codes include a fast recovery code for frequently accessed data and a higher storage efficiency code for less frequently accessed data. State data is tracked to ascertain frequency of access to the file. One of the erasure codes is dynamically selected based on the tracked data, with the focus of the code select to lower recovery costs, and the data is encoded with the selected erasure code. Accordingly, the original coding of the write file is subject to change based on the tracked state data.

Abstract: In order to establish a connection between electronic devices, after receiving an advertising packet from another electronic device, an electronic device compares a performance metric associated with the communication with the other electronic device with a threshold value. Based on the comparison, the electronic device provides pairing-intent information specifying a pairing intent for the electronic device and the other electronic device for presentation by the other electronic device. Moreover, after receiving additional pairing-intent information specifying the pairing intent from the other electronic device, the electronic device establishes the connection with the other electronic device when the additional pairing-intent information matches the pairing-intent information.

If the text character is identified as a class one character, operations include maintaining use of a current font, even if different from the supporting font, to render the class one character on the display. If the text character is identified as a class two character, operations include switching from the current font to another font only if the class two character is unsupported by the current font. Operations also include rendering the received text character on the display.

In some embodiments, search with autosuggest includes determining a plurality of potential query suggestions for a partially entered query string; and automatically suggesting a plurality of queries based on a query count for each of the queries. For example, the query count can correspond to a popularity of the query. In some implementations, the query count can be determined based on a number of times that the query was received, and the plurality of queries can be listed based on the popularity of each of the plurality of queries (e.g., to facilitate display of more popular queries higher in the list of suggested queries).

Abstract: Embodiments of the invention relate to a para-virtual I/O system. A consistent para-virtual I.O system architecture is provided with a new virtual disk interface and a semantic journaling mechanism. The virtual disk interface is extended with two primitives for flushing and ordering I/O, both of the primitives being exported to para-virtual I/O drivers in a guest operating system. The ordering primitive guarantees ordering of preceeding writes, and the flushing primitive enforces order and durability. The guest drivers selectively uses both of these primitives based on semantics of the data being persisted from the para-virtual cache hierarchy to physical disk. The order of committed writes is enforced in order to enable a consistent start recovered after a crash.

Abstract: A digital-to-analog converter has an output. An analog-to-digital converter senses a voltage at the output of the digital-to-analog converter and generates a digital voltage signal. A source mismatch estimator processes the digital voltage signal to output an error signal indicative of current source mismatch within the digital-to-analog converter. An error code generator generates a digital calibration signal from the error signal. The digital calibration signal is converted by a redundancy digital-to-analog converter to an analog compensation signal for application to the output of analog-to-digital converter to nullify effects of the current source mismatch.

Abstract: Methods and systems are disclosed for key management for on-the-fly hardware decryption within an integrated circuit. Encrypted information is received from an external memory and stored in an input buffer within the integrated circuit. The encrypted information includes one or more encrypted key blobs. The encrypted key blobs include one or more secret keys for encrypted code associated with one or more encrypted software images stored within the external memory. A key-encryption key (KEK) code for the encrypted key blobs is received from an internal data storage medium within the integrated circuit, and the KEK code is used to generate one or more key-encryption keys (KEKs). A decryption system then decrypts the encrypted key blobs using the KEKs to obtain the secret keys, and the decryption system decrypts the encrypted code using the secret keys. The resulting decrypted software code is then available for further processing.

Abstract: Methods and systems are disclosed for on-the-fly decryption within an integrated circuit that adds zero additional cycles of latency within the overall decryption system performance. A decryption system within a processing system integrated circuit generates an encrypted counter value using an address while encrypted code associated with an encrypted software image is being obtained from an external memory using the address. The decryption system then uses the encrypted counter value to decrypt the encrypted code and to output decrypted code that can be further processed. A secret key and an encryption engine can be used to generate the encrypted counter value, and an exclusive-OR logic block can process the encrypted counter value and the encrypted code to generate the decrypted code. By pre-generating the encrypted counter value, additional cycle latency is avoided. Other similar data independent encryption/decryption techniques can also be used such as output feedback encryption/decryption modes.
