Signal processing device and vehicle communication device including the same

A signal processing device comprising:

• a first processor configured to receive a first message including a sensor signal in a vehicle based on a first communication scheme, and to perform signal processing of the received first message;
• a second processor configured to receive a second message including a communication message received from an external source based on a second communication scheme, and to perform signal processing of the received second message;
• a shared memory configured to operate to transmit the first message or the second message between the first processor and the second processor;
• a first memory including an IPC channel;
• and
• a second memory storing sensor data including vehicle speed data,
• wherein the shared memory is comprised in the first memory.

A vehicle communication device comprising a signal processing device,

• wherein the signal processing device comprises:
• a first processor configured to receive a first message including a sensor signal in a vehicle based on a first communication scheme, and to perform signal processing of the received first message;
• a second processor configured to receive a second message including a communication message received from an external source based on a second communication scheme, and to perform signal processing of the received second message;
• and
• a shared memory configured to operate to transmit the first message or the second message between the first processor and the second processor, wherein
• the first processor comprises a first manager including a first cache for inter-processor communication (IPC);
• and
• the second processor comprises a second manager including a timer and a second cache for the IPC.
