NEC Licenses Technology to ESS to Develop Enhanced VR Series Microprocessor System Controller Chips

-ESS-Designed Controllers Provide Enhanced Features and Performance For Digital Consumer Devices.-

TOKYO, SANTA CLARA, and FREMONT, Calif., November 5, 2001--NEC Corporation (NEC) (Nasdaq: NIPNY) (FTSE: 6701q.i) (TSE: 6701) and NEC Electronics Inc., its wholly owned subsidiary in the United States, together with ESS Technology, Inc. (Nasdaq: ESST), a leading provider of silicon solutions for digital video, digital home systems and home networking solutions, announced today a technology licensing and marketing agreement.

Under the terms of the agreement, ESS will develop enhanced versions of NEC's system controller chips used in digital consumer electronic devices, such as set-top boxes. ESS and NEC will jointly promote the ESS system controller devices for NEC's VR SeriesTM MIPS(R) RISC microprocessors worldwide. This agreement enables NEC to focus on delivering its leading microprocessor technology, while ESS can focus on enhancing the feature sets of the system controllers.

The ESS-designed system controller chips will support a wide range of software and hardware features. When combined with a VR Series microprocessor, the system controller chips from ESS will provide the necessary features and performance required by today's smart digital consumer devices, including set-top boxes, thin client devices and Internet appliances. The ESS system controller chips integrate peripheral functions such as a memory controller, DMA controller, PCI bus host bridge and a local bus host bridge. The first of the new family of system controller devices from ESS are expected to be available in the second half of 2002.

Robert Blair, president & CEO of ESS Technology, Inc said, "This agreement is the latest step in ESS's Digital Home System (DHS) strategy of developing a portfolio of products for the emerging digital consumer electronics market. In addition to our position as the leading supplier of digital video player chips, the launch of this new family of system controller chips for NEC's microprocessors will enhance ESS's position in the market for digital consumer electronic devices where NEC's MIPS-based processors have a leading market share."

Karl Auker, associate general manager for NEC Electronics' VR Series Microprocessor Strategic Business Unit stated, "NEC Electronics is committed to working with ESS to provide a solid roadmap for system controller solutions that are strong complements to our VR Series microprocessors. The enhanced system controller family from ESS Technology will be the perfect companion chips to our VR5432TM and new VR5500TM microprocessors, providing complete system solutions that will enable the next generation of high-performance digital consumer products."

NEC's VR Series 64-bit MIPS-based Reduced Instruction Set Computer (RISC) microprocessors provide comprehensive solutions for embedded system designers. Developed around the MIPS RISC architecture, all of the VR Series microprocessors are backward-code-compatible and highly scalable. Furthermore, NEC Electronics is committed to providing complete design environment support for its VR Series microprocessors by offering a wide range of companion chipsets, development platforms and a comprehensive set of development tools.

NEC and ESS Technology will provide efficient and flexible design tools to reduce development risks and time to market. Tools include development systems and evaluation boards containing NEC microprocessors and ESS system controllers. These systems are designed as a platform to develop and test peripheral hardware, device drivers and software applications as well as an evaluation board and reference design. ESS and NEC will also make available complete software design support packages for leading embedded operating systems, such as Wind River(R) VxWorksTM, Microsoft(R) Windows(R) CE, and Linux(R).
