Abstract
The invention provides circuitry for carrying out a square root operation. The circuitry utilizes iteration circuitry for carrying out a plurality of iterations. The iteration circuitry includes a circuit for calculating a root multiple, the root multiple being a multiple of a current quotient value. The root multiple is used by the iteration circuitry to modify a current remainder.
Claims16
Circuitry for carrying out a square root operation, said circuitry comprising:
- iteration circuitry for carrying out a plurality of iterations, said iteration circuitry comprising means for calculating at least one root multiple from one of a positive quotient value and a negative quotient value, said root multiple being used by said iteration circuitry to modify a current remainder.
Circuitry for carrying out an arithmetic operation with respect to at least one number, said at least one number having a first length format or a second length format, said first length format being different to said second length format, said operation requiring a plurality of iterations, said circuitry comprising:
- iteration circuitry for carrying out a predetermined number of iterations, wherein the number of iterations is dependent on whether said number has a first or a second length format.
Dependencies are inferred from the claim text.
