Improv Systems Inc. and ARM Ltd. have released a system-on-chip development environment for mixing Improv DSPs with ARM's embedded RISC processors. The Jazz Rehearsal product consists of a development board that implements Improv's configurable methodology and its Jazz DSP cores, and interfaces directly with the ARM Integrator board, said Cary Ussery, founder, president and chief executive officer of Improv (Beverly, Mass.). "Jazz Rehearsal allows designers to model the integration of ARM's RISC microprocessor cores with a Jazz-based SoC [system-on-chip]," said Ussery. The goal is "to demonstrate ARM processors working with Jazz DSPs for the networking market."
Rehearsal uses an FPGA implementation of up to three Jazz processors, each situated on an individual, stackable card. The board links with the ARM Integrator/AP platform through the Cambridge, England, company's high-performance Amba bus interface, allowing designers to develop and test applications based on a combination of the two companies' technologies. This solution incorporates ARM's two recently announced Amba configurations for the SoC system architecture: the Multi-layer Advanced High-performance Bus (AHB) and AHB-Lite.
Improv has a similar offering linking a Jazz-based board to MIPS development boards. Ussery said the environment is integrated with Improv's development tool suite, which features a Java-based application development and debug environment, an advanced compiler, a graphical environment for customizing the Jazz processor and a cycle-accurate instruction-set simulator.
The first public demonstration of the ARM version of Jazz Rehearsal will be an implementation of Improv's voice-over-packet integrated access device SoC at the Networld+Interop show in Las Vegas this week. The demo can be viewed at both the ARM booth (No. 8838) and the Improv booth (No. 8644). The Jazz Rehearsal Card for the ARM Integrator ASIC Platform is available now for $7,500. Delive ry lead time is four to eight weeks. See www.improvsys.com.

Virtual Silicon Technology Inc. and Hynix Semiconductor Inc. (formerly Hyundai Electronics) will jointly develop and market products using Virtual Silicon's advanced nonvolatile memory libraries, eSi-NVM. The companies said Hynix will initially deploy the technology in its high-performance embedded products starting next year.
The pairing will allow system-on-chip designers to embed E2PROM or flash in Hynix Semiconductor's baseline 0.25-micron CMOS logic processes. Virtual Silicon claims the eSi-NVM cells are a low-cost and low-power embedded-memory solution for many market segments, such as wireless communications, portable computing, consumer electronics and industrial automation.
Hynix plans to use this technology for its internally developed products slated for rollout in the first quarter of 2002, and will also make it available to its foundry customers. Virtual Sili con cites the small size the eSi-NVM cell as its selling point over E2PROM technology, claiming the eSi-NVM cell size is more than 40 percent smaller.
