In a multichannel design, period also decides how many channels you can process on a wire, or on one signal. Where you have more channels than you can process on one path, or wire, in a conventional design, you need to duplicate the datapath and hardware to accommodate the channels that do not fit in a single wire. If the processing for each channel or path is not exactly the same, DSP Builder advanced blockset supports vector or array data and performs the hardware and datapath duplication for you. You can use a wire with a one dimensional data type to represent multiple parallel datapaths. DSP Builder IP and Primitive library blocks, such as adder, delay and multiplier blocks, all support vector inputs, or fat wires, so that you can easily connect models using a single bus as if it is a single wire.
