Tensilica Licenses IBM CoreConnect Bus To Enable Xtensa Processor 'Plug and Play' in IBM SOCs; Tensilica Becomes First Configurable IP Vendor to License CoreConnect Bus

Update: Cadence Completes Acquisition of Tensilica (Apr 24, 2013)

SANTA CLARA, Calif.--(BUSINESS WIRE)--Sept. 30, 2002-- Tensilica,(R) Inc., the leader in configurable and extensible processors, today announced that it has become the first configurable processor IP vendor to license IBM's CoreConnect(TM) on-chip bus architecture. Tensilica also announced the availability of an Xtensa(R)-to-CoreConnect bus bridge in the fourth quarter of 2002. The bridge interfaces Tensilica's configurable Xtensa processor to the IBM CoreConnect bus so customers can quickly merge multiple Xtensa processors to CoreConnect-based System-on-Chip (SOC) designs.

This announcement highlights the relationship between IBM and Tensilica, which has grown to meet the needs of their many joint customers. Tensilica was the first member of IBM's Blue Logic IP Collaboration Program, announced March 5, 2002. Additionally, Tensilica's Xtensa core has been proven in IBM's Blue Logic ASIC design methodology for IBM's SA27E 0.18-micron and advanced Cu-11 0.13-micron technologies. Tensilica and IBM have several common customer designs in volume production.

"The IBM CoreConnect bus has been very popular and widely used among SOC designers," stated Bernie Rosenthal, senior vice president of marketing for Tensilica. "By providing customers with a configurable bridge building tool that automatically generates Xtensa to CoreConnect bridges, customers will be able to essentially 'plug and play' their customized Xtensa processors into CoreConnect-based SoCs."

"As the charter member of our Blue Logic IP Collaboration Program, Tensilica is a key partner and an excellent example of the type of third-party IP that we like to make available to our customers," said Tom Reeves, VP ASICs, IBM Microelectronics. "The configurability of the Xtensa processor makes it a natural complement to IBM's existing IP cores portfolio. The availability of an Xtensa-to-CoreConnect bridge makes it quicker and easier for customers to design in Xtensa processors."

Xtensa continues to be the only configurable and extensible processor with comprehensive and automatic software, modeling and EDA support. Changes made by the designer to extend the Xtensa processor hardware -- adding instructions, registers, processor state and custom execution units and now the CoreConnect bus interface -- are immediately and automatically reflected in the entire software tool chain, significantly reducing design complexity and time-to-market. By comparison, competitive architectures require the user to manually adjust compilers, assemblers, debuggers, operating systems, instruction set simulators, co-verification models and EDA implementation scripts when user-defined hardware changes are made to the processor RTL.
