nextWorkingSet

Map the working set in1 to the line buffer interface in Cadence^® Stratus HLS by using the coder.hdl.interface pragma. Calculate the average of the values in the working set.

function out = line_buffer_average(in1)
    coder.hdl.interface(in1,"Line Buffer",[20 20],FillMethod="Wrap");
    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 nextWorkingSet method. It generates the working sets for each pixel of the input image.

image = rand(20,20);
ws = hdl.WorkingSet(image,[3 3],FillMethod="Wrap");
[ws,workingSet] = ws.nextWorkingSet();
while ws.hasNextWorkingSet()
    out = line_buffer_average(workingSet);
    [ws,workingSet] = ws.nextWorkingSet();
end
