Abstract: A host computer for emulating a target system includes a host memory, a CPU, and a host GPU. The host memory is configured to store a library of graphics functions and a VM. The VM includes a section of emulated memory storing target code configured to execute on the target system. The CPU is configured to execute the VM to emulate the target system. The VM is configured to execute the target code and intercept a graphics function call in the target code. The VM is further configured to redirect the graphics function call to a corresponding graphics function in the library of graphics functions stored in the host memory. The host GPU is configured to execute the corresponding graphics function to determine at least one feature configured to be rendered on a display coupled to the host GPU.

Abstract: A host computer for virtualizing a target multicore processor includes a host CPU and a host memory storing a virtual time object and a VM, the VM including target code. The host CPU executes the plurality of threads in parallel on corresponding virtual cores, including a first thread executing on a first virtual core and a second thread executing on a second virtual core. The VM assigns a designation to the first virtual core to increment the virtual time object by a first count of a first plurality of instructions executed in the first thread over a first duration. The VM moves the designation to the second virtual core in response to detecting an event that defines an end of the first duration. The second virtual core increments the virtual time object by a second count of instructions executed in the second thread over a second duration.
