Abstract
Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, mechanisms, and means for providing a JTAG to system bus interface for accessing embedded analysis system(s). JTAG commands are received and converted into commands sent out a bus to a device including an embedded analysis instrument, with results received over the bus forwarded out the JTAG interface to an external device. Such a JTAG to system bus interface may eliminate the need to provide separate JTAG TAP interfaces on each ASIC of a board, and/or eliminate the need to daisy chain multiple TAP interfaces of multiple ASICs in order to provide a single TAP interface for accessing the multiple embedded testing instruments.
