What is The application of SJ-MSD adder to mean value filtering processing about?

Based on the transformations of SJ-MSD (modified-signed digit) addition and the principle of SJ-MSD adder, the application of SJ-MSD adder of TOC to mean value filtering (ternary optical computer) is introduced. The realization of mean filtering processing is presented by reconfiguring SJ-MSD adders on TOP (ternary optical processor) in detail. Experiments show that the mean filter processing in TOC can be carried out successfully with a multiple of SJ-MSD parallel adders with large number of data bits. It also shows a great promise and advantages for the application of TOC in digital image processing and other respects. ## 1. Introduction Adder is the most basic unit of a computer for numerical calculation. Adder's speed determines the time consumption of computer during numerical calculation. However, in general addition operation, there is a carry propagation process from the least significant digital position to the highest significant digital position. This process causes the carry delay in addition, which seriously restricts the speed of computer for numerical calculation. In order to overcome the problem, a binary adder with carry look-ahead part is adopted in electronic com
