65nm Process

ANTENNA DATA Typically performed by

ASIC/FPGA 24-48 antenna streams

per base station ~123 Mbps per antenna stream = 3-6 Gbps of antenna data Too much to process on DSP

USER DATA Typically done on DSP ~19Mbps per user channel Brought in by shared EMIF I/O restrictions limit

~123 Mbps per antenna stream

= 3-6 Gbps of antenna data But can now be processed

by DSP

USER DATA Better core and I/O allow for

increased density ~128 user channels per DSP ~19 Mbps per user channel = 2.5 Gbps of user data per DSP RIO also enables flexible

Elegant Solution Delivers Lower BOM Costs

High-Density TX, RX Solution: 10 EDGE-enabled carriers on a single chip - 3 carriers and 69 users for TD-SCDMA – 10 MHz, 2-antenna, 3-sector solution for WiMAX

Lower System BOM Costs: CPRI interface allows for direct connectivity to the backplane without a FPGADaisy-chaining of TCI6487 DSP allows for antenna streams to be distributed/combined without FPGAs

Scalable: # of sectors and # of users can be increased by the adding additional TCI6487 DSP

Lower Latencies: Improved latencies address high-speed data applications Ease of Design/Test: Single software build on every device enables an easier development and test environment
