As LTE deployment becomes a reality, operators are favoring system-on-chip (SoC) architectures to keep their network costs low while maintaining and improving their service. Supporting a successful LTE transition requires a number of innovations in digital signal processor (DSP) design. Texas Instruments has developed a powerful and innovative multicore SoC architecture called “KeyStone” designed to support WCDMA and LTE efficiently and reduce costs. The KeyStone multicore architecture enables true multi-standard (LTE, WCDMA) solutions with dedicated WCDMA and LTE accelerators. This paper explores how TI’s KeyStone multicore architecture enables Layer 2 and transport processing on an LTE base station.
