Quad-Port Memory Blocks in Radiation-Tolerant FPGAs: An Application for Image Processing Systems

This paper presents a novel memory architecture for implementing quad port memories in radiation tolerant FPGAs. The hardware solution proposed here uses only dual port memories and ensures that appropriate memory speed can be achieved while working as quad port memory. Efficient memory architecture has been used to transform dual port memory into quad port memory without using any redundant memory. The discrete wavelet transform has been effectively implemented using the proposed architecture on the Actel RTAX FPGA.
