INTEGRATED CIRCUIT DEVICE AND METHOD FOR ENABLING CROSS-CONTEXT ACCESS

摘要

An integrated circuit device (200) comprising at least one instruction processing module (205) for performing operations on data in accordance with received instructions. The at least one instruction processing module (205) comprises at least one context selector unit (245) arranged to selectively provide access to at least one process attribute(s) (510, 515, 525, 530) within a plurality of process contexts (310, 320, 330) in accordance with at least one context selector value (450) received thereby. The at least one instruction processing module (205) is arranged to receive at least one instruction (500) comprising at least one context indication (502, 504, 506, 508) for at least one process attribute (510, 515, 525, 530) with which at least one operation is to be performed, provide at least one context selector value (450) based at least partly on the at least one context indication (502, 504, 506, 508) to the at least one context selector unit (245), and execute the at least one operation to be performed with the at least one process attribute (510, 15, 525, 530) for at least one process context (310, 320, 330) to which the context selector unit (245) provides access in accordance with the at least one context selector value (450).
