Integrated Device Technology and Texas Instruments have developed a 3G basestation development platform to speed design times and provide quicker access to systems for software teams.
In the process, IDT said its pre-processing switch (PPS) is now fully interoperable with digital signal processors (DSP) from TI.
IDT designed the pre-processor to offload DSP tasks. Aimed at wireless baseband processing applications that use Serial RapidIO interconnect, it carries out byte and packet-level manipulations in order to reduce the load on DSPs.
The AMC70K2000 development platform integrates the IDT PPS with four TI DSPs on an advanced mezzanine card (AMC), which plugs into a PC.
The platform enables realistic case studies for moving tasks and operations from the DSPs to the PPS and observing the system responses. The AMC deploys the four fabric-connected TMS320C6455/6482 devices and the IDT 70K2000 offering a RapidIO interface of 40 lanes and 22 ports and accelerating each DSP in a cluster by up to 20 per cent.
It has a three Gigabit Ethernet backplane, one line I/O; DRAM DDR2 up to 128 Mbytes per DSP; flash storage (serial high speed) and I2C; JTAG for system boot master, MMC; MMC control for IPMI with additional applications; and a local-power option for stand-alone operation.
A built-in expansion port offers the ready addition of a daughter card supporting other Serial RapidIO endpoints, including the new IDT 10G serial buffer.
