New TMS320C6452 Broadens TIís DSP Portfolio Delivering 2x the Channels Per Dollar for High Performance Applications


TI also Expands Roadmap with its C6455 1.2-GHz, Fastest Single Core DSP for Telecom Infrastructure, Medical and Emerging Applications

HOUSTON .- Designers of telecom access infrastructure equipment can now double the number of VoIP and conferencing channels per dollar, lowering system cost and power while boosting overall performance. Texas Instruments Incorporated (TI) (NYSE: TXN) today announced the availability of the high-performance, cost-effective TMS320C6452 digital signal processor (DSP) designed to optimize price and performance for todayís process intensive multi-channel infrastructure and medical imaging systems. Simultaneously, TI has strengthened its performance leadership position by announcing that the TMS320C6455 DSP at 1.2-GHz is the world‚Äôs fastest single core DSP. For more information on the C6452 and C6455 DSPs, see

ďOver the years, TIís C6000TM DSP platform has proven to be reliable, cost effective and easy to use,Ē said Simon Chouldjian, VP of hardware engineering, AltiGen. ďTI continually improves its C6000 DSPs with higher speeds and more efficient instruction sets. With the high-performance products and great support AltiGen has received during the product development lifecycle, it is easy to see why we are committed to leveraging TIís roadmap.Ē

C6452 DSP Key Customer Benefits

With a more than 30 percent price reduction over TIís popular TMS320C6415T DSPs, the new code compatible 900 MHz C6452 DSP allows designers to quickly and easily migrate their designs from the widely deployed C641x based products. Therefore, this broad base of customers can benefit from the advanced communications peripherals, expanded memory, heightened performance and cost benefits of the new C6452 device.

Based on TIís enhanced TMS320C64x+TM core, the C6452 DSP delivers double the L1 cache memory and 40 percent more L2 cache than the C6415T, giving customers more headroom to easily add differentiating features to their designs. The C6452 DSP also includes two gigabit Ethernet MAC ports and one gigabit switch, which greatly improves the efficiency of multi-chip designs by automatically monitoring the data stream to ensure that only the appropriate packets consume DSP performance. Additionally, the device is equipped with a Telecom Serial Interface Port (TSIP), providing a seamless connection to common telecom serial data streams, ultimately improving performance while increasing robustness and flexibility.

‚ÄĘ Twice the channels per dollar - Increasing channel density is critical for infrastructure designs since, in most instances, rack space is fixed. The C6452 DSPís 900 MHz clock rate, expanded memory, advanced peripherals and ability to be easily daisy-chained using the two SGMII (Serial Gigabit Media Independent Interface) ports gives system-level designers the building blocks needed to increase channel density. The C6452 DSPís lower price compared to the C6415T DSP, plus system software from third parties such as Adaptive Digital Technologies, enables twice the channels per dollar for echo cancellation, conferencing and VoIP/G.PAK applications.

‚ÄĘ Reduced application bottlenecks - The C6452 DSP has two SGMII Ethernet MAC ports and a gigabit switch to enable each individual DSP in the system to process only those packets associated with that DSPís function. The SGMII is a widely used technology for connecting high-speed Ethernet devices at the MAC level. TIís switch adds a decision gate that can, for example, be used to distinguish between voice and data traffic. If a specific DSP on the card is dedicated entirely to voice processing, it blocks data traffic from entering, which makes much more effective use of its processing bandwidth.

‚ÄĘ Enhanced IO peripherals and more on-chip memory than the C6415T DSP - The C6452 DSPís 66-MHz PCI interface has double the data rate. Similarly, the DDR2 interface doubles the external memory bandwidth. L1 instruction and data caches are doubled to 32 Kbytes. There is a 40 percent increase in the L2 cache size.

Independent Verification: TIís C6455 DSP is Worldís Fastest

TI is committed to investing in its high performance roadmap and is expanding its DSP portfolio with the introduction of its 1.2-GHz TMS320C6455 DSP. The C6455 at 1.2-GHz is available at the previous 1-GHz price, giving developers a significant performance boost at no additional cost. The results of Berkeley Design Technology, Inc.ís (BDTI) benchmark analysis of the C6455 device placed it atop all other single core programmable DSPs for speed with a BDTImark2000TM score of 13170. Because BDTI BenchmarksTM measure performance on a collection of algorithms, they provide performance expectations for real-world applications and are the most widely used digital signal processing benchmarks in the world.

For the most processing-intensive applications requiring the highest performance and processor-to-processor communication, the C6455 DSP combines high bandwidth peripheral integration (gigabit Ethernet MAC), Serial RapidIO (sRIO) and increased memory (2MB of L2 memory) into one single device.
