Title:
システムデバッグ方法、システムデバッグ装置、データプロセッサ及び無線通信インタフェースIC、インタフェース方法
Document Type and Number:
Japanese Patent JP4574714
Kind Code:
B2
Abstract:
A pulse transmission technique is used for wireless communication between a microcomputer (13) having a debugging support circuit (17) and a debugger (13). The pulse transmission technique is based on magnetic field coupling between a first coil (14) provided for the microcomputer and a second coil (8) coupled with the debugger. During an initialization operation, the microcomputer performs a process of configuring a communication condition of the wireless communication to perform the wireless communication. The microcomputer awaits control from the debugger when the microcomputer establishes communication with the debugger. The debugger awaits establishment of the communication and proceeds to control of the microcomputer in accordance with the wireless communication. It is possible to provide contactless interface for system debugging without the need for a large antenna or a large-scale circuit for modulation and demodulation.
