An advanced processor comprises a plurality of multithreaded processor cores each having a data cache and instruction cache. A data switch interconnect is coupled to each of the processor cores and configured to pass information among the processor cores. A messaging network is coupled to each of the processor cores and a plurality of communication ports. In one aspect of an embodiment of the invention, the data switch interconnect is coupled to each of the processor cores by its respective data cache, and the messaging network is coupled to each of the processor cores by its respective message station. Advantages of the invention include the ability to provide high bandwidth communications between computer systems and memory in an efficient and cost-effective manner.

Advanced processor translation lookaside buffer management in a multithreaded system

Advanced processors for executing software applications on different operating system are presented including: a number of processor cores each configured to execute multiple threads, wherein each of the number of processor cores includes a data cache and an instruction cache; a data switch interconnect ring arrangement directly coupled with the data cache of each of the number of processor cores and configured to pass memory related information among the number of processor cores; a messaging network directly coupled with the instruction cache of each of the number of processor cores and a number of communication ports; and a memory management unit (MMU) coupled with each of the number of processor cores, the MMU having a first translation-lookaside buffer (TLB) portion, a second TLB portion, and a third TLB portion, wherein each TLB portion is operable in several modes, wherein each TLB portion includes a number of entries.
