Latest Patents

Joseph Harfouch holds a patent for "Accelerated prime sieving using architecture-optimized partial prime product table." This invention teaches a variation of GCD-based sieving, which builds tables of prime products while intentionally restricting the size of table entries to fit within a single machine word. This combination allows for the mixing of advantages from the two most popular sieves while retaining the straightforward structure of the simpler one. The divisor length restriction can provide significant savings in the number of long divisions, implemented with only two very specific primitives. These primitives offer better optimization capabilities than a fully generic multiword arithmetic library. He has 1 patent to his name.
