An apparatus including a ROM, a selector, and a detector. The ROM has a partitions, each stored as plaintext, and a encrypted digests, each comprising an encrypted version of a first digest associated with a corresponding one of the partitions. The selector selects one or more partitions responsive to an interrupt. The detector generates the interrupt at a combination of intervals and event occurrences, and accesses the one or more partitions and corresponding one or more encrypted digests upon assertion of the interrupt, and directs a microprocessor to generate corresponding one or more second digests corresponding to the one or more partitions and corresponding one or more decrypted digests corresponding to the one or more encrypted digests using the same algorithms and key that were employed to generate the first message digest and encrypted digests, and compares the one or more second digests with the one or more decrypted digests, and precludes the operation if the one or more second digests and the one or more decrypted digests are not pair wise equal.

An apparatus including a ROM, an event detector, and a tamper detector. The ROM has BIOS contents stored as plaintext, and an encrypted digest. The encrypted digest is an encrypted version of a first digest corresponding to the BIOS contents. The event detector generates an interrupt that interrupts operation of the system upon occurrence of an event. The tamper detector is operatively coupled to the ROM and accesses the BIOS contents and the encrypted digest upon assertion of the interrupt, and directs a microprocessor to generate a second digest corresponding to the BIOS contents and a decrypted digest corresponding to the encrypted digest using the same algorithms and key that were employed to generate the first digest and the encrypted digest, and compares the second message digest with the decrypted message digest, and precludes the operation of the microprocessor if the second digest and the decrypted digest are not equal.

The output buffer is coupled to a first voltage source providing a first supply voltage and used for generating an output signal at an output terminal according to an input signal. The output buffer includes first and second transistors and a self-bias circuit. The first and second transistors are cascaded between the output terminal and a reference voltage. The self-bias circuit is coupled to the output terminal and the control electrode of the first transistor. When the output buffer does not receive the first supply voltage, the self-bias circuit provides a first bias voltage to the control electrode of the first transistor according to the output signal to decrease voltage differences between the control electrode and the input and output electrodes of the first transistor to be lower than a predetermined voltage.

Phonetic transcriptions of a speech signal are obtained from an acoustic model. Phonetic spellings matching the phonetic transcriptions are obtained according to the phonetic transcriptions and a syllable acoustic lexicon.

Each phonetic spelling is matched to a candidate sentence table; a word probability of each phonetic spelling matching a word in a sentence of the sentence table are obtained; and the word probabilities of the phonetic spellings are calculated so as to obtain the text sequence probabilities. The text sequence corresponding to a largest one of the sequence probabilities is selected as a recognition result of the speech signal.
Abstract:
A universal serial bus (USB) transaction translator is provided along with a micro-frame synchronization method. A device interface is coupled to a device via a device bus, and a host interface is coupled to a host via a host bus. At least two buffers are configured to store data. A controller stores the data in the buffers alternately. A start-of-frame (SOF) counter is used to count the SOF packets, with the counting value of the SOF counter being compared to a predefined value. Specifically, the controller resets a SOF timer for sending the SOF packet when the counting value achieves or exceeds the predefined value, such that the SOF packet and an isochronous timestamp packet (ITP) from the host are sent at the same time. Further, the controller delays the sending of the SOF packet for a period of time according to the ITP from the host.
