The invention discloses an apparatus, a method, and a system for ensuring quality of service for multi-threading processor cores. The invention provides a simultaneous multi-threading (SMT) processorcore capable of thread-based biasing with respect to execution resources. The SMT processor includes priority controller circuitry to determine a thread priority value for each of a plurality of threads to be executed by the SMT processor core and to generate a priority vector comprising the thread priority value of each of the plurality of threads. The SMT processor further includes thread selector circuitry to make execution cycle assignments of a pipeline by assigning to each of the plurality of threads a portion of the pipeline's execution cycles based on each thread's priority value in the priority vector. The thread selector circuitry is further to select, from the plurality of threads, tasks to be processed by the pipeline based on the execution cycle assignments. 本申请公开了用于确保多线程处理器核的服务质量的装置、方法和系统。具有相对于执行资源的基
