Serial RapidIO switch simplifies system
design
A high-performance switch delivers the performance, power and configurability needed to build reliable high-performance RapidIO-based systems for a wide range of applications.
The Tundra Tsi574 Serial RapidIO switch is a high-performance device with patent-pending technology that delivers the performance, power and configurability that designers of embedded designs need to build reliable, high-performance RapidIO-based systems for a wide range of applications such as wireless basestations, media gateways, video infrastructure and DSP-intensive image processing The Tundra Tsi574 features: link flexibility through mixed port widths and speeds; hardware multicast for improved distributed processing performance; supervised traffic flow for increased performance and fabric management; an enhanced serdes for the lowest power solution; and a low noise core, flip-chip packaging, adjustable drive current, adjustable pre-emphasis and receive equalisation per lane, all contributing to high signal integrity

RapidIO interfaces hit the ground running
The Tsi400 RapidIO to PCI-X bus bridge and the Tsi500 RapidIO multiport switch are the first commercially available RapidIO system interconnect products.
Ideally suited for high-performance processor connectivity, the target applications such as media gateways and baseband will benefit from the switch's ability to route packets to over 64,000 endpoints, independent unicast and multicast routing mechanisms, and error management extensions that provide proactive issue notification to the fabric controller.
This switch interconnects Serial RapidIO-enabled microprocessors, DSPs, FPGAs, and peripheral devices, supporting an aggregate bandwidth of 40Gbit/s.
Scalable for a broad spectrum of networking, wireless and video infrastructure applications, designers can take advantage of configuration options to efficiently manage power requirements for high-performance.
The Tsi574's port flexibility supports up to four 4x mode ports or up to eight 1x mode ports, with each port configurable to 1.25, 2.5 or 3.125Gbit/s.
All the ports switch of the switch are completely independent, and will support mixed configurations of width and speed.
"When combined with our TMS320TCI6482, the industry's first high-performance RapidIO-enabled DSP, we expect the multicast capability of the Tsi574 Serial RapidIO switch to enhance performance and simplify system design for wireless applications", said Alan Gatherer, Chief Technology Officer for Texas Instruments Communications Infrastructure and Voice Group.
"System designers will benefit from new architectural basestation design possibilities by using serial RapidIO enabled products".
"High-performance, scalable switches, such as the Tsi574, are an essential part of the RapidIO ecosystem".
The Tsi574 integrates several features that allow the switch to leverage the high-performance capabilities of the Serial RapidIO interconnect protocol.
The switch has low latency between ports, and each port has optional store and forward or cut-through modes providing peak performance in any configuration.
In addition, there is extensive traffic management through three fabric scheduling algorithms and programmable buffer depth for guaranteed bandwidth.
Fabric performance monitoring enables supervised and managed traffic flows that result in real-time fabric optimisation.
The Tsi574 offers low noise core, flip chip packaging, adjustable drive current, adjustable pre-emphasis and receive equalisation per lane, which all contribute to the highest possible standards in signal integrity and performance.
"The launch of the Tundra Tsi574 switch signals momentum building behind Tundra's growing RapidIO product portfolio, which has the depth to respond to a wide spectrum of customers' needs for the wireless and video markets", said Jag Bolaria, Senior Analyst at the Linley Group.
"With multiple RapidIO switches that are scalable for different price/performance points and include advanced capabilities such as hardware multicast, Tundra continues to strengthen its claim as the leader in RapidIO system interconnect".
The Tsi574 Serial RapidIO switch will be sampling in September 2006.
Volume pricing for the Tsi574 is under US $80.
The Tsi574 is implemented in 0.13um CMOS technology, packaged in a 21 x 21mm, 399-ball FCBGA package.
The Tsi574 uses the same package as the Tsi564A, and the two devices are software compatible.
The device requires 1.2 and 3.3V power supplies and is rated for industrial and commercial temperature operation.
The switch also supports IEEE1149.6 JTAG standard for high speed interconnects.
