Hardware definition language generation for frame-based processing
An automatic code generation application is used to automatically generate code and build programs from a textual model or graphical model for implementation on the computational platform based on the design. One or more model elements may be capable of frame-based data processing. Various options and optimizations are used to generate Hardware Description Language (HDL) code for the frame-based model elements.
1. A computer-implemented method of generating hardware description language (HDL) code for an executable graphical block diagram model of a hardware system, said method comprising:
transforming, using a processor of the computer, a first component of the graphical block diagram model into an intermediate representation, the first component processing frame-based input data and representing a first computational element of the hardware system, wherein a frame is a temporal collection of data samples acquired over a predetermined time period; and
serializing at least a portion of the first component, wherein serializing the first component further comprises:
generating HDL code for a buffer storing at least a portion of the frame-based input data to the first component;
generating HDL code for at least one delay unit delaying processing of the at least a portion of the frame-based input data to the first component; and
generating HDL code for at least a portion of the first component, the generated HDL code for the at least a portion of the first component including the generated HDL code for the buffer and the generated HDL code for the at least one delay unit.
2. The computer-implemented method of claim 1 , wherein the buffer is shared between the first component and a second component, the second component representing a second computational element of the hardware system.
3. The computer-implemented method of claim 2 , wherein the buffer is used to hold output of the second component.
4. The computer-implemented method of claim 1 , further comprising:
linearizing the at least a portion of the frame-based input data to the first component.
5. The computer-implemented method of claim 1 , further comprising:
generating an intermediate representation of the graphical block diagram model.
6. The computer-implemented method of claim 5 , further comprising:
optimizing the intermediate representation of the graphical block diagram model; and
generating HDL from the optimized intermediate representation of the graphical block diagram model.
7. A computer-implemented system for generating hardware description language (HDL) code for an executable model of a hardware system, said computer-implemented system comprising:
a model comprising a first component that accepts frame-based input data, the first component representing a computational element of the hardware system, wherein a frame is a temporal collection of data samples acquired over a predetermined time period; and
generated HDL code for the model, the generated HDL code serializing the first component wherein the generated HDL code serializing the first component further comprises:
HDL code for a buffer storing at least a portion of the frame-based input data to the first component; and
HDL code for at least one delay unit delaying processing of the at least a portion of the frame-based input data to the first component.
8. The computer-implemented system of claim 7 , wherein the buffer is shared between the first component and a second component, the second component representing a second computational element of the hardware system.
9. The computer-implemented system of claim 7 , further comprising:
generated HDL code linearizing the at least a portion of the frame-based input data to the first component.
