TMC to Port DMNA to Tensilica's Xtensa Processors for Video and Imaging Applications.

TOKYO -- Tensilica(R), Inc., today announced that Techno Mathematical Co., Ltd. (TMC) will port TMC's unique DMNA (Digital Media New Algorithm) to Tensilica's Xtensa V and Xtensa LX processors and deliver Tensilica Instruction Extensions (TIE) code specifically designed to accelerate the DMNA algorithm. Tensilica licensees can incorporate these unique TIE instruction extensions into new Xtensa processors. DMNA is a revolutionary new algorithm that significantly reduces the computing load in multimedia applications.

"The combination of Tensilica's Xtensa configurable processor technology and our unique DMNA algorithm can achieve ultra-efficient performance for complex multimedia applications," stated Masafumi Tanaka, president of TMC.

TMC's DMNA algorithm reduces the arithmetic load, enabling high-speed processing of video and imaging applications without compromising quality. The algorithm uses a number of proprietary techniques to simplify the tedious calculations required for high-quality imaging. DMNA can reduce power consumption by decreasing the operating frequencies of CPUs by approximately a third. It also can provide an increased frame rate and higher picture quality without increasing the frequency of a CPU.

"Several of our customers have expressed interest in TMC's DMNA algorithm for products ranging from cell phones to digital cameras and other handheld devices with intense video and image processing requirements," stated Larry Przywara, director of strategic alliances for Tensilica.

The DMNA port to the Tensilica processors is expected to be complete in the first quarter of 2005.
