For Immediate Release

Corelis Introduces SUN™ version of High- Performance
JTAG Emulator for ARC’s Tangent Processors

The previously released NetICE-ARC JTAG emulator is now available in a SUN version, to
provide a very cost-effective development tool for configurable processors.

Cerritos, CA, September 28, 2001 -- Corelis Inc., today unveiled the SUN version of their emulator for ARC Cores (LSE:ARK) high-performance processor family.  The new NetICE-ARC/S emulator utilizes the standard JTAG port on ARC’s Tangent processor to provide access to its unique on-chip debug facilities.  The emulator includes the powerful MetaWare Solaris compatible SeeCodeTM source-level debugger.  For JTAG emulation access, the NetICE-ARC/S uses a LAN-based (Ethernet) JTAG controller.

Unlike conventional real-time emulators that rely on bulky and expensive external hardware pods, the Corelis emulator uses the JTAG standard test access port to access the internal debug resources available on ARC’s Tangent processor.  This eliminates the need for external pods, thus reducing the cost and electrical loading of the target system.  Since the debug resources used by the emulator are integrated on the target processor, the emulator automatically supports any clock speed at which the target system runs. In addition to these benefits, the use of the JTAG interface also ensures that processor access is maintained even when the user’s software 'hangs' or otherwise runs out of control. 

Programs and data can be downloaded to any part of the system RAM through the JTAG port without the need for a resident loader program or a ROM emulator. The standard four-wire JTAG interface allows it to be connected to ARC’s processor, and any future processor developed by ARC. Thus, switching processors from one design to the next does not obsolete a user's investment in their emulator hardware.

Phil Barnard, Product Manager for Development Tools at ARC Cores, said, "Corelis brings to ARC’s platform solution a wealth of experience with high-performance JTAG emulation and low-cost development tools, and will help us support customers that prefer working with high-performance SUN-based JTAG development tools." Phil Barnard added: “Corelis, by providing the option to expand their JTAG emulators for ARC’s cores with boundary-scan test and in-system programming, will dramatically reduce our customers overall prototype debug time and time to market.”

"The introduction of the SUN version of the NetICE-ARC/S JTAG emulator, enables ARC’s Tangent processors to be even more easily integrated intohigh-performance embedded designs and result in products being brought to market much faster", said Menachem Blasberg, President and CEO of Corelis. "Having a fully featured low-cost SUN-based development tool with expandability for other ARC processors planned in the future will make it a very cost effective solution for hardware and software developers that prefer a SUN-based development and debug environment.”

ARC Cores On-chip debug logic

The ARC on-chip debug capabilities are unique in the embedded market place, and provide three main advantages to the system developer – non-intrusive memory access, no debug firmware required and multi-core debug.

To support real-time debugging, the on-chip logic enables you to examine memory locations without stopping the processor.  Debug operations can be achieved with no resident code running on the CPU, resulting in zero memory overhead for full system debug.  In the case where your SoC design utilizes multiple ARC cores, the ARC Tangent processor provides a mechanism to multiplex a single debug link over multiple processor instantiations, minimizing the number of pins required for debugging.

The NetICE-ARC/SUN is shipping now.
