The method comprises: at the system circuitry, performing one of the plurality of functions; applying a debug configuration to the at least one debug unit; and at the at least one debug unit, monitoring for a characteristic in the system circuitry's performance of the one of the plurality of functions according to that debug configuration, and reporting to the debug controller. | 08-13-2015 |
20140013161 | DEBUG ARCHITECTURE - Roughly described, a method of sending a message from a source unit to a destination unit both forming part of a hierarchical debug architecture on a chip, the units in the hierarchy using a protocol in which each unit has an internal address which is the same base address, and in which each unit addresses other units using addresses derivable relative to that unit's internal address given positions of other units in the hierarchy, comprising: the source unit in a first level of the hierarchy sending a message comprising a destination address of the destination unit, the destination address being relative to the source unit's internal address, and an intermediate unit in a second level of the hierarchy: adding an offset to the destination address to form a rebased destination address, being relative to the intermediate unit's internal address, and routing the rebased message onto the destination unit. | 01-09-2014 |
20140013011 | DEBUG ARCHITECTURE - Roughly described, an integrated circuit chip comprises a plurality of peripheral circuits, each peripheral circuit connected to a respective debug unit; a shared hub; and between each respective debug unit and the shared hub, a single physical interface configured to transport both configuration data and event data, wherein the interface is configured such that if an event occurs whilst the interface is transporting configuration data, the interface interrupts the transport of the configuration data in order to transport the event data. | 01-09-2014 |

20130055030 | Data Processing Apparatus and Related Methods of Debugging Processing Circuitry - A data processing apparatus, comprising processing circuitry, which in use, generates data and debug circuitry arranged to debug operation of the processing circuitry. The processing circuitry includes bus circuitry arranged to pass data at least one of into and out of the processing apparatus over a communication bus. The debug circuitry comprises monitoring circuitry arranged to monitor the data generated, in use, by the processing circuitry and generate a stream of trace elements. An interface unit is arranged to interface, using the bus circuitry, the trace elements generated by the monitoring circuitry onto the communication bus to be output, in use, from the processing apparatus using the communication bus. The interface unit comprises a controller which is arranged to control operation of the interface unit independently of the operation of the processing circuitry. | 02-28-2013 |
