Title:
MULTIPLE-POINT MULTIPLICATION OPERATION SYSTEM AND METHOD, AND GRAPHICS PROCESSOR, ELECTRONIC APPARATUS AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/045665
Kind Code:
A1
Abstract:
The present disclosure relates to the field of data processing. Provided are a multiple-point multiplication operation system, a graphics processor, an electronic apparatus, an electronic device and a multiple-point multiplication operation method, which aim to reduce the storage space required by a multiple-point multiplication operation. The multiple-point multiplication operation system comprises a control module and a point doubling module. The control module is configured to: when a target point R updated in an (i-1)th cycle is equal to an infinity point and if a target element determined on the basis of an i-th group of coefficients in an i-th cycle is a negative value of a preset element, update the target point R using the preset element in the i-th cycle, and set a first signal as a first preset value. The point doubling module is configured to: when the target point R updated in the (i-1)th cycle is not equal to the infinity point and if the first signal is the first preset value, perform swapping between a subtrahend and a minuend in an original point doubling operation of the target point R in the i-th cycle, and execute a point doubling operation on the basis of a subtrahend and a minuend between which swapping has been performed.
