DSP chips form heart of new navy sonar system

TMS320C6455 DSP chips will be the processing core for ATRIMT (acoustic transmit receive integration module) sonar, used in the US navy's latest destroyers.

Raytheon has selected TMS320C6455 digital signal processors (DSPs) from Texas Instruments for use in the US Navy's DDG 1000 Zumwalt class destroyer program.

Raytheon serves as the main mission-systems equipment integrator for all electronic and combat systems for the Navy.

Tuned for a myriad of infrastructure equipment including high-end telecom, wireless infrastructure, and video and imaging applications, TI's 1GHz C6455 DSP is the processing workhorse for ATRIMT (acoustic transmit receive integration module) sonar, a sonar signal subsystem that incorporates multiple boards, each processing four channels of sonar.

Peak performance, small code size, large on-chip memory and integrated peripherals, including the Ethernet MAC and Serial RapidIO bus for interprocessor communications, and optical Ethernet interface, all elevated the selection of the C6455 DSP to support the design and development of this revolutionary surface combatant.

DDG 1000 Zumwalt, the first ship of a class of multimission destroyers tailored for land attack and naval support, will provide forward presence and deterrence operating as part of joint and combined expeditionary forces in ground campaigns and littoral dominance.

Texas Instruments is a prime supplier of signal processing technology to the sonar portion of the total ship computing environment (TSCE), an open architecture infrastructure designed by Raytheon to integrate all combat and peacetime operations into a single, common network-computing environment, including the overall operating system, command/control communications, and middleware and infrastructure services.
