  • Patent number: 8265087
    Abstract: A gateway apparatus for performing transfer control of frame data between communication channels includes a routing map that stores ID information about the frame data and information about a communication channel that uses the ID information, and a search engine unit that routes the frame data to a transfer destination on the basis of the ID information of the frame data received and the routing map. The search engine unit does not transfer the frame data to the transfer destination when the ID information about the frame data received is ID information that is not used in the communication channel through which the frame data is received.

  • Patent number: 8122316
    Abstract: An error detector has a parity bit generator which generates error detection data for data strings sent from a CPU I/F to a memory, a parity checker which detects an error in the data strings output from the memory based on the error detection data, and a selector circuit which switchingly outputs the data from the parity bit generator and the data from a CPU which sends diagnostic data. While the selector circuit is switched to output the data from the CPU, based on the error detection data output from the selector circuit, the error detector conducts a failure diagnosis of error detection functions including at least one of the parity bit generator and the parity checker.

  • Publication number: 20090248241
    Abstract: Functional information acquired before and after an event occurrence is held on an on-chip MRAM built in a data processor, thus preventing the held functional information from being falsified and erased. An automobile recorder of the present invention comprises a one-chip data processor coupled to signal lines transmitting functional information indicating vehicle conditions and an external memory. The data processor comprises an input circuit which takes input of functional information, an MRAM for temporarily storing functional information, and a central processing unit (CPU). The CPU performs wrap-around control for storing functional information into the MRAM. The CPU also performs disabling control for disabling storing of functional information when the amount of new information being stored on the MRAM by wrap-around control in response to and following a certain event occurrence has reached a specific quantity that is less than a storage capacity from the initial address to the end address.

  • Patent number: 5675240
    Abstract: A switching regulator is composed of digital circuits only. A switching regulator (30) comprises a driver (2) for directly controlling the operation of a switching transistor (1), and an OR gate (6) for determining the logic issued by the driver (2). An output terminal (Q) of an RS flip-flop (5) is connected to one input end of the OR gate (6), the output of a timer (40c) is applied to a set terminal (S) of the RS flip-flop (5), and the output of a comparator (4) is applied to a reset terminal (R1) through an OR gate (7). At a non-reverse input end of the comparator (4), a reference voltage (VE) is applied by a D/A convertor (40b), while a feedback voltage (VFB) is applied to a reverse input end. Accordingly, chopping of the switching transistor (1) is done on the basis of a rectangular pulse.
