Multiple resources and performance prediction
نویسنده
چکیده
This paper describes the origins and history of multiple resource theory in accounting for di erences in dual task interference. One particular application of the theory, the 4-dimensional multiple resources model, is described in detail, positing that there will be greater interference between two tasks to the extent that they share stages (perceptual/cognitive vs response) sensory modalities (auditory vs visual), codes (visual vs spatial) and channels of visual information (focal vs ambient). A computational rendering of this model is then presented. Examples are given of how the model predicts interference di erences in operational environments. Finally, three challenges to the model are outlined regarding task demand coding, task allocation and visual resource competition.

متن کاملBranch Prediction Architectures for 64-bit Address Space
Processor architectures will increasingly rely on issuing multiple instructions to make full use of available processor resources. When issuing multiple instructions on conventional processors, accurate branch prediction is critical to performance; mispredicted branches may mean that ten’s of cycles may be wasted. Architectures combining very effective branch prediction mechanisms coupled with ...
