Abstract

THE TMS320 PROCESSOR FAMILY, FROM TEXAS INSTRUMENTS, INCLUDES SEVERAL HIGH PERFORMANCE CMOS MICROPROCESSORS SUITED TO LOW-POWER DIGITAL SIGNAL PROCESSING (DSP) APPLICATIONS. DVP INC., HAS DEMONSTRATED THE FEASIBILITY OF APPLYING THE TECHNOLOGY THAT THESE CHIPS HAVE PROVIDED TO AN INNOVATIVE DATA ACQUISITION SYSTEM BUILT AROUND NATIONAL SEMICONDUCTOR'S CIMBUS (CMOS INDUSTRIAL MICROCOMPUTER BUS). THE TMS320 PROCESSORS CAN EFFICIENTLY IMPLEMENT FFTs (FAST FOURIER TRANSFORMS), DIGITAL FILTERS, MATH FUNCTIONS, AND OTHER COMPUTATIONALLY INTENSIVE ALGORITHMS NEEDED FOR REAL-TIME SIGNAL PROCESSING. TWO TMS320 DSP BOARDS, WHICH FILL AN IMPORTANT NEED EXISTING IN BOTH THE COMMERCIAL SECTOR AND THE UNITED STATES GOVERNMENT, HAVE BEEN DESIGNED FOR THE CIMBUS. THE DVP DESIGN HAS BEEN MADE EXTREMELY FLEXIBLE BY USING FIRMWARE ROUTINES IN APPROPRIATE SECTIONS OF THE HARDWARE CIRCUITRY. THIS DESIGN PRACTICE WILL ENSURE A BROAD RANGE OF APPLICABILITY AND GREATLY INCREASE THE PRODUCT'S LONGEVITY. IN ADDITION, AS PART OF THE PHASE I WORK EFFORT, SEVERAL PROGRAMS HAVE BEEN DEVELOPED TO IMPLEMENT RESIDENT SIGNAL PROCESSING FUNCTIONS. THESE BOARDS WILL HAVE CAPABIITIES THAT NO OTHER EXISTING CIMBUS BOARDS CAN FULFILL. THE PHASE II INTENT OF THIS UNIQUE DESIGN PROJECT IS TO FABRICATE AND TEST THESE BOARDS AND THEIR ASSOCIATED SOFTWARE.
