Abstract: An apparatus and method is described herein for providing robust speculative code section abort control mechanisms. Hardware is able to track speculative code region abort events, conditions, and/or scenarios, such as an explicit abort instruction, a data conflict, a speculative timer expiration, a disallowed instruction attribute or type, etc. And hardware, firmware, software, or a combination thereof makes an abort determination based on the tracked abort events. As an example, hardware may make an initial abort determination based on one or more predefined events or choose to pass the event information up to a firmware or software handler to make such an abort determination. Upon determining an abort of a speculative code region is to be performed, hardware, firmware, software, or a combination thereof performs the abort, which may include following a fallback path specified by hardware or software. And to enable testing of such a fallback path, in one implementation, hardware provides software a mechanism to always abort speculative code regions.

Abstract: This disclosure provides techniques and apparatuses to enable early, run-ahead handling of IC and ITLB misses by decoupling the ITLB and IC tag lookups from the IC data (instruction bytes) accesses, and making ITLB and IC tag lookups run ahead of the IC data accesses. This allows overlapping the ITLB and IC miss stall cycles with older instruction byte reads or older IC misses, resulting in fewer stalls than previous implementations and improved performance

Abstract: A display terminal and a method for displaying content on the display terminal are embodied and broadly disclosed herein. The method may include displaying an indicator that indicates a presence of at least one new content available in a channel; displaying a list of the at least one new content in response to an acknowledgement request corresponding to the indicator; and connecting to the channel to display the at least one new content in response to an input, wherein the input is a selection of one or more of the at least one new content in the displayed list.

Abstract: A method and apparatus for providing fairness in a multi-processing element environment is herein described. Mask elements are utilized to associated portions of a reservation station with each processing element, while still allowing common access to another portion of reservation station entries. Additionally, bias logic biases selection of processing elements in a pipeline away from a processing element associated with a blocking stall to provide fair utilization of the pipeline.
