Abstract

Under the sponsorship of the AFRL AISM program, LMFS teamed with ADI to successfully demonstrate the layout transfer, fabrication and verification of a commercial equivalent Analog Devices Signal Processor (ADSP) 21020 into LMFS´s radiation hardened process. This report contains activities related to layout transfer, hardware fabrication, test, and electrical characterization. ADSP-21020 is a widely used floating point digital signal processor (DSP) in commercial applications. The Military Satellite Communications Program Office showed a high level of interest in a radiation tolerant digital signal processor (RTDSP) based on the ADSP-21020. A radiation tolerant ADSP-21020 will be an enabling factor in several applications such as image processing, digital filtering and convolution, fast Fourier transforms, data encryption, packet switching, and guidance/navigation processing. In addition, RTDSP can support new space systems applications
