Abstract
A device manages data for a digital signal processor. The device includes an external random access memory (RAM), configured to store channel specific data for plural different channels; and a microprocessor, in communication with the external RAM. When receiving the packet, in a transport layer processing the packet, the microprocessor determines a channel of the plural different channels corresponding to an indication in a transport layer header of the received packet. The microprocessor fetches channel specific data specific to the channel into an internal memory internal to the microprocessor from the external RAM, by the transport layer, before the packet is passed to an application layer, thereby avoiding a wait for reading the packet at the application layer.
