Latest Patents

One of his latest patents is titled "External trace synchronization via periodic sampling." This method involves tracing a multi-tasking embedded pipelined processor by executing compiled code that includes trace controls. Tracing is initiated when the execution of the compiled code begins and is stopped upon completion. A trace record is formed during this process, which includes a processor mode indication, application space identity value, and an instruction architecture set mode indication.

Another significant patent is "System debug and trace system and method, and applications thereof." This patent describes an embedded system or system on chip (SoC) that features a secure JTAG system. This system provides secure on-chip control, capture, and export of on-chip information in an embedded environment to a probe. It includes encryption logic associated with a JTAG subsystem and decryption logic in the probe for encrypted JTAG read traffic. The bi-directional encryption and decryption of JTAG traffic ensures the security of debug data and authentication of valid probe/target interfaces.
