Spectron Microsystems Inc, Goleta, California has introduced the SPOX operating system and a Windows-based signal processor resource manager and application programming interface, and has licensed Microsoft Corp and Media Vision Inc, Fremont, California to use them. Microsoft says the software architecture will support multifunction audio and communication device capabilities on Windows-based personal computers and that it will deliver the host-based software and Spectron will deliver the SPOX operating system. The Windows-based architecture will enable applications to take advantage of a signal processor when one is present, regardless of which chip is used. SPOX will manage input-output and algorithm execution on the signal processor, and Microsoft’s audio product unit plans to make a device driver kit available OEM in the first half of 1994. Chip makers backing the operating system include Analog Devices Inc; Motorola Semiconductor Products Inc; National Semiconductor Corp; and Texas Instruments Inc. Media Vision has licensed both SPOX and the resource manager and programming interface for its products.
