Abstract
Official abstract text for this publication.
An aspect includes providing rollback support in an exposed-pipeline processing element. A system includes the exposed-pipeline processing element with rollback support logic. The rollback support logic is configured to detect an error associated with execution of an instruction in the exposed-pipeline processing element. The rollback support logic determines whether the exposed-pipeline processing element supports replay of the instruction for a predetermined number of cycles. Based on determining that the exposed-pipeline processing element supports replay of the instruction, a rollback action is performed in the exposed-pipeline processing element to attempt recovery from the error.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for rollback support in an exposed-pipeline processing element, the system comprising: the exposed-pipeline processing element comprising rollback support logic, a result buffer, an effective address buffer, and an operand buffer; and the rollback support logic configured to perform a method comprising: storing results of an arithmetic logic unit pipeline of the exposed-pipeline processing element to the result buffer selectively based on determi…
