Abstract: The present invention is related to a RF security apparatus and method. The method includes steps of: preparing an electronic card having a circuit loop and a signal storage unit, which at least has one code signal; providing a reader for cooperating with the electronic card, wherein the reader has a sensing unit and a logic circuit, and through a wireless transmission between the circuit loop and the sensing unit, the logic circuit performs a comparison of the preset code signal; and connecting to a flash drive through the reader, wherein electronic data contained in the flash drive is accessible only after the comparison between the reader and the electronic card is performed.

Abstract: A dedicated debugging facility for tracing hardware and software faults in a distributed digital system. An event data capture circuit is integrated into each processing node in a distributed multinode system for capturing event data within each node under software control. The captured event data is stored in one of a plurality of variable-length trace data buffers in the node processor memory space for analysis or transfer. These dedicated trace data acquisition circuits provide continuously available trace data for the hardware and software functions within each node. Each variable-length trace data entry is stored in the trace data buffers according to a format of this invention that permits collection and assembly of trace data entries from throughout the distributed multinode system to debug local hardware or software and to debug internodal interconnection hardware and software.
