The following is a list that helps interpret this diagram: • The direction of the arrows indicates either bus master or bus slave. • The arrow originates at a bus master and terminates at a bus slave. • The direction of the arrows does not indicate the direction of data flow. Data flow is typically bi-directional for each of the documented bus paths. • The pattern of each arrow's line indicates the clock rate at which it is operating, either DSP/2, DSP/3, or DSP/6 clock rate. • Some peripherals may have multiple instances shown in the diagram. A peripheral may have multiple instances shown for a variety of reasons, some of which are described below: – The peripheral/module has master port(s) for data transfers, as well as slave port(s) for register access, data access, and/or memory access. Examples of these peripherals are C64x+ megamodule, EDMA3, CF/ATA, USB, EMAC, VPSS, VLYNQ, and HPI. – The peripheral/module has a master port as well as slave memories. Examples of these are the C64x+ megamodule and the ARM subsystem. Figure 4-1.
