A Proposal for Hardware-Assisted Arithmetic OverflowDetection for Array and Bitfield OperationsDarek MihockaIntel Corp.Darek.Mihocka@Intel.comJens TroegerIntel Corp.Jens.Troeger@Intel.comAbstractDetecting arithmetic overflow during summation operationsis vital to ensuring correct and secure behavior of manytypes of code. For example, applying transformations tosigned integer pixel co-ordinates without any overflowdetection may result in pixels rendering at unexpectednegative co-ordinates, summi
