Abstract

See full text

An integrated circuit can include a communication endpoint configured to maintain a communication link with a host computer, a queue configured to receive a plurality of host commands from the host computer via the communication link, and a processor configured to execute a device runtime. The processor, responsive to executing the device runtime, is configured to perform validation of the host commands read from the queue and selectively execute the host commands based on a result of the validation on a per host command basis. The host commands are executable by the processor to manage functions of the integrated circuit. The queue is implemented in a region of memory that is shared by the integrated circuit and the host computer.
