Abstract
A reusable hardware intellectual property (IP) component protocol method for a system-on-chip is disclosed, which uses a software function to describe hardware behavior. A calling of the software corresponds to hardware IP component's execution, and the procedure of the software function corresponds to the behavior of the hardware IP. Therefore, the hardware IP can be reused as a software function.
Claims9
A reusable hardware intellectual property (IP) protocol method for a system-on-chip device, describing a hardware behavior via a software function, the method comprising:
- (A) determining whether any parameters are needed, corresponding to a determination of whether a hardware IP needs any parameters;
- wherein if parameters are needed, proceeding to step (B), and if not, proceeding to step (C);
- (B) inputting at least one function parameter, corresponding to inputting at least one hardware function parameter to the hardware IP;
- (C) calling the software function corresponding to inputting a request signal to the hardware IP;
- (D) waiting for a return value from the software function corresponding to waiting for an acknowledge signal from the hardware IP;
- (E) sending back the return value from the software function corresponding to outputting a result data from the hardware IP when the request signal and the acknowledge signal are enabled;
- and (F) ending the software function corresponding to resetting or booting the hardware IP.
