I have the following problem that I would like your opinion on how to solve elegantly:
I have a block A (say a standard sync block with some memory--eg an fir filter) which has input x(t) and output y(t) and is pretty computationally intensive. I would like to add the following functionality to it: Add a new input s(t) to A which can be 0 or 1. When s(t)=1 the block operates as before ie, it processes x(t) to generate y(t). If s(t)=0 I would like it to output y(t)=0 and consume the appropriate x(t)'s from the input. This way when s(t)=0 block A essentially "does not work". This is pretty straightforward to code if I modify the work function of block A. However, block A for me is a pretty complicated hierarchical block, so I don't have access to its "work" function. One way to do this is to rewrite the whole hierarchical block A as a flat block and then do as suggested above. Is there a better way? Thanks Achilleas
