Abstract
This paper introduces a new parallel algorithm for the low pass digital image filtering using a systolic array. This new algorithm is faster than the old one [14]. This is due to the fact that the old algorithm carries out the addition operations in a sequential mode. But in our new design these addition operations are divided into two groups which can be performed in parallel. One group will be performed on one half of the systolic array and the other on the second half, that is, by folding. This parallelism reduces the time required for the whole process by almost quarter the time of the old algorithm.
