Abstract
A system includes a host debugger to carry out a debugging flow on a computing device and a debug controller to couple the host debugger to the computing device. The debug controller receives a bit stream from the host debugger, converts the incoming bit stream into a command according to a protocol, determines whether the command is a first-stage read command or a second-stage read command, and issues the first-stage read command to a data path of the computing device. If the command is a second-stage read command, the debug controller causes a reservation register of the debug controller to provide a data value or status indication to the host debugger through the interface. The reservation register contains read data returned by the first-stage read command and, in response to the second-stage read command, provides a status indication when the first-stage read command has not yet returned read data.
