A kind of asynchronous process machine system and method have multiple screw threads

摘要

Embodiment, which provides a kind of asynchronous process machine, has multiple screw threads. The asynchronous process machine includes that program counter (PC) logical AND instruction cache unit includes that multiple PC logics are configured to execute the instruction of branch prediction and the multiple threads of ring predication, and determine the addresses target PC for caching multiple threads. The processor further includes that command memory is configured as caching multiple threads, according to the addresses target PC from PC logical AND instruction cache units. The processor further includes multithreading (MT) scheduling unit, is combined into the single instruction for combining thread for dispatching multiple thread instruction streams and incorporating from command memory. In addition, MT register window registers include the operand of multiple threads, with the register file for the corresponding registers being mapped in multiple windows.
