SIS Microelectronics Chosen to Provide OakDSPCore® Support for TSMCs Customers

Longmont, CO - October 18, 1999 - SIS Microelectronics, Inc., a wholly owned subsidiary of Aspec Technology (NASDAQ: ASPC), is a leading independent IP provider and system-on-chip (SOC) design resource. The company announced an agreement with Taiwan Semiconductor Manufacturing Company (TSMC) today, establishing SIS Microelectronics as the preferred company to provide porting and customer support for the OakDSPCore. TSMC licenses the OakDSPCore from the DSP Group of Israel.

Under the agreement, SIS will supply its 0.25-micron and 0.18-micron implementations of the OakDSPCore to TSMC foundry customers. The agreement further calls for SIS to provide support directly to TSMC customers wishing to include OakDSPCore technology in their designs. SIS will offer timing accurate HDL models of the core, as well as phantom physical blocks for use during layout. Upon completion of verification, SIS will instantiate the core and release the designs to TSMC.

The OakDSPCore is a 16-bit, general purpose, high-speed DSP core designed for speech and audio processing, telecommunications, digital-cellular and embedded-control applications. The low-power, low-voltage product is the DSP Group's second generation DSP core.

"SIS has had a long relationship with the DSP Group and its technology licensees," said Bill Burkard, president of SIS Microelectronics. "The agreement with TSMC allows us to support TSMC's customers with state-of-the-art DSP implementations for SOC designs."

"TSMC recognizes the value of third-party relationships in support of high-level IP," said Roger Fisher Sr., director of marketing at TSMC. "This agreement will allow our customers to directly leverage SIS's expertise in developing and implementing DSP Group's cores."
