Real-time multi-dimensional processing hardware designs research activities. Final report

摘要

In this final report, we summarize some of our results from September 1989 to October 1990. The design, construction, and testing of a four-processor prototype multi-processor (RTP) board using TI TMS320C25 DSP chips has been completed and is reported upon in our separately submitted ''Final Report on the ''RADON TRANSFORM COMPUTER'' Project.'' The design of our fully custom CMOS VLSI chip has been completed. The chip has been designed, the layout completed, and the chip is now going through its final pre-fabrication simulations. We are now finishing the extensive detailed final documentation of the R/Bchip. This extensive documentation will be provided to Steve Azevedo when we have submitted the chip for fabrication. The present status of the custom chip design activity is summarized in Section II. Evaluations of the hardware requirements for fast filtering of data for filtered backprojection (item 3) have been completed and are summarized in our separately submitted ''Final Report on the ''RADON TRANSFORM COMPUTER'' Project.'' We briefly summarize the new custom CMOS VLSI unified Radon transform/backprojection IC architecture, layout, and simulated performance.
