Xilinx and Tensilica announce configurable processor support for programmable systems design.Xilinx, Inc. (Nasdaq:XLNX) and Tensilica, Inc., a new Xilinx AllianceCORE program member, have announced that Tensilica's Xtensa-V configurable processors now support Xilinx FPGAs. Leveraging Tensilica's web-based Processor Generator and the new Virtex-II-based XT2000-X processor emulation system, system designers can now iterate it·er·ate
tr.v. it·er·at·ed, it·er·at·ing, it·er·ates
To say or perform again; repeat. See Synonyms at repeat.
[Latin iter , implement, and debug To correct a problem in hardware or software. Debugging software means locating the errors in the source code (the program logic). Debugging hardware means finding errors in the circuit design (logical circuits) or in the physical interconnections of the circuits. custom Xtensa processor configurations and view the results in Xilinx FPGAs within hours. Designers can run Xtensa processor emulations in real hardware at speeds closer to actual system requirements To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer system. These pre-requisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. , given the Virtex-II-based emulation board runs 50% faster than previous Tensilica FPGA (Field Programmable Gate Array) A type of gate array that is programmed in the field rather than in a semiconductor fab. Containing up to hundreds of thousands of gates, there are a variety of FPGA architectures on the market. emulation boards.
"Tensilica has made evaluation of Xtensa core configurations fast and easy now that their configuration tool and the XT2000-X emulation board supports the Xilinx design flow. It has dramatically reduced our development time," said Toshiaki Ohno, senior manager at NEC's IP Network Division. "The short compile times we get with the Xilinx ISE Ise (ē`sā), city (1990 pop. 104,164), Mie prefecture, S Honshu, Japan, on Ise Bay. It is one of the foremost religious centers of Shinto, the site of the shrines of Ise. software is a great advantage, and we are able to achieve higher performance using the Xilinx emulation system than previous emulation boards."
"We are impressed by the capabilities of the Virtex-II devices from Xilinx," said Steve Roddy, director of product marketing at Tensilica. "We configured the Xtensa processor to accelerate an MPEG-4 decoder system and created a demonstration for a recent trade show running real-time video and audio decode (1) To convert coded data back into its original form. Contrast with encode.
(2) Same as decrypt. See cryptography.
(cryptography) decode - To apply decryption. implemented fully in software running on the Xtensa processor on our board. This really showcases the power and performance of our configurable, extensible processor and the new Xilinx emulation system."
The Xtensa configurable and extensible microprocessor architecture provides a powerful, integrated hardware and software development environment. Designers can create customized processor solutions with specialized execution units, register files and instructions using the Xtensa processor generator. Through this process, developers can simultaneously tune both application software and processor hardware to meet application-specific speed, power and feature goals.
Tensilica customers who purchase the XT2000-X emulation system receive fully automated support for the emulation board through the Processor Generator. The generator creates the RTL (Register Transfer Level) A high-level hardware description language (HDL) for defining digital circuits. The circuits are described as a collection of registers, Boolean equations, control logic such as "if-then-else" statements as well as complex event sequences; source code for the Xtensa processor and associated interface logic for the emulation platform and then automatically runs the design through the Xilinx ISE design software to generate the programming files for the emulation board. Designers can now create a new processor and go from concept to hardware in a matter of hours.
Tensilica has also recently announced that the Xtensa Processor Generator supports a configuration option to include a bridge to IBM's CoreConnect bus architecture. As a result, users of both Tensilica's and Xilinx's technologies can develop complex programmable systems using IBM's CoreConnect bus structure and any combination of Xtensa processors, Xilinx MicroBlaze soft processor cores, high-performance Virtex-II Pro devices with embedded PowerPC processors General-purpose PowerPC processors
