Best-Selling High-Performance TMS320C64x(TM) DSP Platform Now Offers
Affordable, Proven Migration Path for High-End Systems
HOUSTON, Dec. 22 /Xinhua-PRNewswire/ -- Allowing designers to transition
to higher-performing digital signal processors (DSPs) without compromising
price, Texas Instruments Incorporated (TI) (NYSE: TXN) today announced the
availability of the cost-effective, high-performance TMS320C6454 DSP.
Targeted for a myriad of infrastructure equipments including high-end
telecom, wireless infrastructure, and video and imaging applications, the new
1-GHz C6454 DSP is based on the improved TMS320C64x+(TM) DSP core and TI’s
highest-performing DSP architecture. The C6454 DSP provides developers with
twice the memory and I/O bandwidth of the popular TMS320C641x DSPs, as well
as other advanced features and specialization that are needed to create next-
generation systems requiring high processing performance and sufficient
memory at an affordable price. Currently, over 10 million C641x DSPs have
been sold to over 400 customers, making it the most deployed high-performance
DSP generation. TI also announced that the TMS320C6455 DSP is in production,
making it the only DSP with Serial RapidIO(TM) (sRIO) in production. For

C6454 DSP Key Customer Benefits
* A 2X improvement in memory and I/O bandwidth over C641x plus gigabit
Ethernet at a similar price to the TMS320C6415 DSP at the same speed
grade
* Similar performance to C6455 DSP for 25% less cost
* Enhanced C64x+ DSP core provides 20% higher cycle performance and
20-30% reduction in code size while providing 100% code compatible with
TMS320C64x TM DSPs.
The C6454 DSP provides an ideal migration path for the many TI customers
who are currently using C641x DSPs by offering full code compatibility and
boosted performance without requiring additional investment in software
engineering. The C6454 DSP achieves 8000 MMAC (million multiply accumulate
cycles per second) and four times the EDMA (enhanced direct memory access)
throughput of the core used in the earlier devices. For new designers
looking for a high-performing DSP in their tailored, flagship infrastructure
applications, including machine vision, medical imaging and digital video
products, the C6454 DSP is the optimal choice. It provides additional
features, such as 1 MB L2 memory, gigabit Ethernet, C64x+ core and increased
DDR2 external memory and cache, and is similarly priced to C641x devices.
For customers who are using the closely related TMS320C6455 DSP, which is TI’
s first mass market product using the C64x+ core and the industry’s first
DSP with a sRIO bus interface to support the interprocessing requirements of
bandwidth-intensive applications, the cost-efficient C6454 DSP offers C64x+
peak performance at an affordable price. Designers can immediately begin
code development for tomorrow’s C6454 DSP products using the C6455
evaluation module (EVM) and DSP Starter Kit (DSK).
“The C6454 DSP is an important enabler for a universal multimedia port
in next-generation mobile networks that require exceptional voice and video
services,” said Gennady Sirota, Vice President of product management and
marketing, Starent Networks. “TI’s commitment to this product contributes
to Starent’s delivery of superior multimedia performance with unrivaled
flexibility and performance. Our ST16 Intelligent Mobile Gateway enhances
the subscriber experience with advanced voice, data, and multimedia
applications while lowering our customers’ operational expenditures.”
Expanding TI’s Highest Performing Portfolio
The new C6454 DSP is the latest addition to TI’s suite of high-
performance solutions, the TMS320C64x generation of DSPs. Comparably priced
with the widely used C641x DSPs but based on the enhanced C64x+ architecture,
the C6454 DSP offers designers a 20 to 30 percent reduction in code size to
decrease system costs. The C6454 DSP also achieves a 20 percent increase in
cycle efficiency due to the core’s specialized instruction set with support
for the frequently performed FFT, FIR and DCT operations.
The C6454 DSP is a natural migration path for C641x DSP developers who
want richer, sophisticated peripherals but for a similar price. High-speed
peripherals include a Gigabit Ethernet MAC and a 66-MHz peripheral component
interconnect (PCI) interface to allow video infrastructure, telecom and video-
imaging customers to meet high-bandwidth interconnections. The C6454 DSP
doubles L1 data and L1 instruction cache and provides a twofold increase in
DDR2 external memory at 533 MHz to provide balanced memory I/O and processor
performance. Since the C6454 DSP is code compatible and is based on the
C64x+ core, customers also profit from a 4x increase in EDMA bandwidth and
twice the number of 16-bit MMACs.
The closely related C6454 DSP is a lower cost alternative to the C6455
DSP that allows customers to reap a $60 saving due to the reduction in on-
chip L2 memory to 1MB and the removal of peripherals, including UTOPIA and
sRIO, the Viterbi coprocessor (VCP2) and Turbo coprocessor (TCP2), which are
not always required in certain designs. For programmers that demand the
highest-performing C64x DSP platform but not necessarily the multi-chip
interconnect capabilities, the C6454 DSP without the sRIO bus is an
affordable, more economical alternative. Developers presently using the
C6455 DSP who will benefit by transitioning to the C6454 DSP will have
minimal hardware redesign since the two devices are completely pin-compatible.
“The C6454 DSP is an attractive option for designers who are ready to
upgrade from C641x DSPs to a higher performing DSP, but do not necessarily
want all the advanced features of the C6455 DSP,” said Danny Petkevich, DSP
platforms marketing manager, Texas Instruments. “The new C6454 DSP device
balances the right amount of performance and affordability for a wider range
of high-end applications.”
Hardware and Software Tools to Ease Development
Designers can immediately begin system development on the C6454 DSP with
the use of the C6455 EVM and DSK. These robust tools provide a complete
modular development platform for both hardware and software. Announced in
early 2006 and now in volume production, the EVM and DSK include TI’s award-
winning Code Composer Studio(TM) Platinum integrated development platform
(IDE) and DSP/BIOS(TM) kernel, allowing customers to start development at a
higher level of abstraction, which leads to easier software portability and
faster time-to-market. Developers can also rely on the industry’s largest
DSP third party network for algorithms and additional tools to produce
sleeker applications cheaper and faster.
