Parallel algorithm for hardware implementation of inverse halftoning

A parallel algorithm and its hardware implementation are proposed for an inverse halftone operation. The algorithm is based on lookup tables from which the inverse halftone value of a pixel is directly determined using a pattern of pixels. A method has been developed that allows accessing more than one value from the lookup table at any time. The lookup table is divided into smaller lookup tables, such that each pattern selected at any time goes to a separate smaller lookup table. The 15-pixel parallel version of the algorithm was tested on sample images and a simple and effective method has been used to overcome quality degradation due to pixel loss in the proposed algorithm. It can provide at least 4 times decrease in lookup table size when compared with a serial lookup table method implemented multiple times for the same number of pixels

A novel technique for fast multiplication

In this paper we present the design of a new high speed multiplication unit. The design is based on non-overlapped scanning of 3-bit fields of the multiplier. In this algorithm the partial products of the multiplicand and three bits of the multiplier are pre-calculated using only hardwired shifts. These partial products are then added using a tree of carry-save-adders, and finally the sum and carry vectors are added using a carry-look-ahead adder. In case of 2's complement multiplication the tree of carry-save-adders also receives a correction output produced in parallel with the partial products. The algorithms is modeled in a hardware description language and its VLSI chip implemented. The performance of the new design is compared with other recent ones proposed in literatur
