Texas Instruments TMS320C6452 Digital Signal Processor (DSP)

Texas Instruments TMS320C6452 Digital Signal Processor (DSP) is a high-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The C6452 device is based on the architecture of third-generation, high-performance, and advanced VelociTI™ Very-Long-Instruction-Word (VLIW). This device performs up to 7200 Million Instructions Per Second (MIPS) at a 900MHz clock rate. The TMS320C6452 DSP features a 3-Port Gigabit Ethernet switch subsystem, two Telecom Serial Interface Ports (TSIP0/1), and one UART (with RTS and CTS Flow Control). This device is ideal for medical diagnostics, machine vision/inspection, radar and sonar, military/aerospace, and communications.
