A method of driving an array of switches comprising supplying the same drive signal to a first drive terminal of a plurality of the switches of an array and supplying second drive signals to a second drive terminal of each of the plurality of switches, the second drive signal supplied to a first of the switches being of a form selected to close the first switch, the form of the second drive signal supplied to the remaining switches being selected to prevent false activation of those switches.

Spectral predictive switching device activation

A method including determining whether a digital signal processor needs a service program stored in a juke box overlay memory, and delivering the service program to the digital signal processor from the juke box overlay memory over a host port interface bus is disclosed.

Delivery of a service program to a digital signal processor within a multiservice processing system

A method and system for a voice multicast hardware accelerator are disclosed in which a network device or system includes a host system coupled to a memory to store data and a line card to interface with a plurality of user devices. The host system is to receive a network packet including voice data, to store the voice data in the memory, and to send a voice packet related to the voice data to the line card without duplication. The voice packet includes descriptor fields for multicasting the voice data. The line card is to multicast selectively the voice data stored in the memory to the plurality of user devices based on the descriptor fields in the voice packet. A multicast hardware accelerator can be used to multicast selectively the voice data.

Method and system for a voice multicast hardware accelerator

A system and method for making available on a dynamic basis a large library of different firmware processing algorithms to each DSP processor engine of a DSP processor array is disclosed. A master DSP engine continuously broadcasts firmware algorithms used in processing a number of types of data from an attached memory to service DSP engines over the channelized serial bus. The DSP array receives PCM data from multiplexed lines of a public switched telephone network and packetized data from an Internet Protocol (IP) network, then each service DSP engine determines a firmware algorithm required to process the type of data received. The service DSP engine processes the received data using that firmware algorithm.
