    摘要: A system includes master modules, at least one multiport slave module, and a scheduler connected by a system bus. The scheduler is configured to provide scheduling information to the multiport slave module. The scheduling information includes master categorization information and anticipated burst information. The anticipated burst information is based on a scheduler determination for an anticipated bus access by an anticipated master module. The master categorization information categorizes the anticipated master.

    摘要: A microcontroller system, such as a system-on-a-chip integrated circuit, including a processor (e.g., a Von Neumann processor), memory, and a memory protection unit (MPU), where the MPU provides execute-only access rights for one or more protected areas of the memory. The MPU can allow instructions fetched from within a protected area to access data in the protected area while preventing instructions fetched from outside the protected area from accessing data in the protected area.

    摘要: A deterministic blinding method for cipher algorithms that employ key-mixing and substitution (S-box) operations uses a masking table constructed with a true mask and a plurality of dummy masks corresponding to every possible S-box input. Each mask is applied in the key-mixing operation (e.g., bitwise XOR) to the cipher key or to round subkeys to generate true and dummy keys or subkeys that are applied to the data blocks within the overall cipher algorithm or within individual cipher rounds. The mask values prevent side-channel statistical analyses from determining the true from the dummy keys or subkeys. The true mask is identifiable to the cipher but not by external observers.

    摘要: A p-channel LDMOS device with a controlled n-type buried layer (NBL) is disclosed. A Shallow Trench Isolation (STI) oxidation is defined, partially or totally covering the drift region length. The NBL layer, which can be defined with the p-well mask, connects to the n-well diffusion, thus providing an evacuation path for electrons generated by impact ionization. High immunity to the Kirk effect is also achieved, resulting in a significantly improved safe-operating-area (SOA). The addition of the NBL deep inside the drift region supports a space-charge depletion region which increases the RESURF effectiveness, thus improving BV. An optimum NBL implanted dose can be set to ensure fully compensated charge balance among n and p doping in the drift region (charge balance conditions). The p-well implanted dose can be further increased to maintain a charge balance, which leads to an Rdson reduction.

    摘要: A bias current is generated for an unbalanced differential pair that is proportional to the transconductance gain of the differential pair. When the transconductance gain varies (e.g., due to temperature variations), the bias current varies in proportion thereby maintaining a constant offset voltage. In some implementations, a voltage to current converter circuit generates the bias current from a constant reference voltage that is independent of temperature and voltage supply variations (e.g., a bandgap reference voltage).

    摘要: A subset of software objects stored in a first segment of non-volatile memory are identified as requiring frequent write operations or otherwise associated with a high endurance requirement. The subset of software objects are move to a second segment of non-volatile memory with a high endurance capacity, due to the application of wear leveling techniques to the second segment of non-volatile memory. The first and second segments of memory can be located in the same memory device or different memory devices.

    摘要: A method for detecting and correcting errors in a memory having a read/write paradigm is presented. In these implementations, various approaches to detect errors on a per word or per group of words basis and correct errors on a per group of words or per page basis, respectively, in relation to a memory and its associated differing read/write operations, are provided. For instance, in one implementation, errors are detected on a per word basis and corrected on a per page basis for a NOR Flash Memory having differing read/write operations of reading on a per word basis and writing on a per page basis. Advantageously, benefits of the various implementations include reduced encoder/decoder complexities, reduced parity overhead requirements, and reduced performance degradation.
