Video and Imaging Application

In video and imaging applications, system designers need to cluster large numbers of DSPs or FPGAs to perform

encoding/decoding/trans coding, or do FFTs (Fast Fourier Transform) on large arrays of data. The RapidIO protocol is optimal

for this DSP/FPGA cluster requirement. However, the analog front-end to the system is usually a sensor with streaming data

terminated in an FPGA (for example, a camera subsystem). This is usually in an PCIe network, often with a PC back-end. In

these applications the designer needs to bridge between a PCIe network and the RapidIO DSP/FPGA cluster. The Tsi721 is

ideal for this application.

Wireless Application

In wireless base stations, the incumbent interconnect technology in the baseband processing cards – LTE, WiMAX, WCDMA,

and TD-SCDMA – is RapidIO. RapidIO connects a cluster of DSPs, processor, and FPGA, locally on the baseband processor

for MAC and PHY layer processing. However, the LTE standard pushes the performance available in existing RapidIO enabled

microprocessors.

The Tsi721 provides wireless OEMs with an additional option to use an x86 processor with superior MIPs in a baseband card

that is predominantly RapidIO. In these card designs, RapidIO is the interconnect between devices and functions as the

backplane interconnect. x86 processors can now be used with other RapidIO devices on the baseband card and leverage the

messaging performance of RapidIO for this peer-to-peer multiprocessor network.
