getWorkingSet

In the following MATLAB^® code, the line_buffer_average function takes working set as the input and maps it to the line buffer interface in Cadence^® Stratus HLS using coder.hdl.interface pragma.

function out = line_buffer_average(in1)
    coder.hdl.interface(in1, "Line Buffer", [20, 20], FillMethod = 'Nearest');
    sum = 0;
    for i = 1:size(in1,1)
        for j = 1:size(in1,2)
            sum = sum + in1(i,j);
        end
    end
    out = sum / numel(in1);
end

The MATLAB test bench demonstrates the usage of the hdl.WorkingSet class and getWorkingSet method. It generates the working sets for each pixel of the input image.

image = rand(20, 20);
ws = hdl.WorkingSet(image, [3 3], FillMethod='Nearest');
for x = 1:20
    for y = 1:20
        workingSet = ws.getWorkingSet(x, y);
        out = line_buffer_average(workingSet);
    end
end
