Code coverage generation through host-device coordination

A system comprising:

• one or more processors to:
• generate code comprising instrumentation to cause a host processor to initialize device memory to store one or more counters to indicate a number of times code is performed by a device processor, wherein the host processor and device processor have different architectures;
• store, in device code, mapping information indicative of a mapping between the counters and source code constructs;
• and
• generate code coverage information based, at least in part, on the counters and the mapping information;
• and
• one or more memory devices to store the code compiled to be performed by the host processor and the code to be performed by the device processor.
