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.

Abstract: A gateway apparatus for performing transfer control of frame data between a plurality of different communication channels is provided with a time stamp unit for adding time stamp information to received frame data and a data discarding unit for determining processing delay of the frame data or abnormality of the apparatus by referring to the time stamp information and for deleting the time stamp information added to the frame data at the time of sending the frame data.

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.

Abstract: An FM-CW radar includes a transmitting section, a mixing section, an A/D conversion section, a storage unit, and a signal processing section. The transmitting section transmits a continuous wave frequency-modulated with a triangular wave. The mixing section mixes the continuous wave transmitted and a reflected wave from a target, to generate a beat wave. The A/D conversion section A/D converts the beat wave into digital data. The storage unit includes a first storage section and a second storage section. The signal processing section reads data from the first storage section to process the read data. The A/D conversion section writes the digital data into the second storage section. The control section switches the first storage section and the second storage section alternately in synchronous with switching between up and down of the triangular wave.

Abstract: Provided is a RAM check unit capable of checking a RAM included in a radar system even when the radar system is in operation. An LSI instructs a high-frequency unit to output a radar-transmitted signal. When a radar-received signal is received from the high-frequency unit, calculation is performed based on the signal. The result of the calculation is transferred to a CPU. The CPU transmits a calculated distance to the outside. When a processing end sensing unit included in the LSI senses termination of radar-received signal processing, an RAM check unit initiates RAM check. When the RAM check is terminated, the high-frequency unit is instructed to output a radar-transmitted signal. Consequently, the RAM check is performed during a period between pieces of radar-received signal processing during which a load on the LSI is light. Thus, the RAM check can be performed even when the radar system is in operation.

Abstract: A communication conversion apparatus achieve efficient conversion without conversion delay and converts messages that effect communication with different communication protocols and schedules. In a message conversion apparatus that performs message conversion of different communication protocols, a routing circuit and a scheduler circuits that perform scheduling of the different communication protocols are separately provided. And time-triggered scheduling and event-triggered scheduling are separately performed. Conversion of FlexRay and CAN messages can be efficiently implemented.

Abstract: A pump body includes a cylindrical first case for housing the plurality of rotary pumps, a second case located coaxially with the first case, and a disk spring located between the first case and the second case. In addition, a fixing means located at an entrance of the concave portion of a housing presses the second case in the insertion direction of the pump body and fixes the second case.
