Title:
COMMUNICATION DEVICE
Document Type and Number:
Japanese Patent JP2019080190
Kind Code:
A
Abstract:
To provide a communication device that can perform signal processing at high speed using a general-purpose device.SOLUTION: An IF circuit 11 converts a received signal into data of a predetermined standard. A GPU 120a performs signal processing on the converted data. When an interrupt due to the signal conversion is received in the IF circuit 11, the CPU 13 sets the transfer destination address of data in the GPU 120a in the IF circuit 11, instructs transfer of the data, and instructs the GPU 120a to start the kernel. The IF circuit 11 receives the instruction from the CPU 13, and transfers the converted data to the transfer destination address of the GPU 120a. The GPU 120a causes the kernel activated in response to an instruction from the CPU 13 to execute signal processing using the data transferred from the IF circuit 11 to the transfer destination address.SELECTED DRAWING: Figure 3
