摘要： An instruction processing system is provided. The system includes a central processing unit (CPU), an m number of memory devices and an instruction control unit. The CPU is capable of being coupled to the m number of memory devices. Further, the CPU is configured to execute one or more instructions of the executable instructions. The m number of memory devices with different access speeds are configured to store the instructions, where m is a natural number greater than 1. The instruction control unit is configured to, based on a track address of a target instruction of a branch instruction stored in a track table, control a memory with a lower speed to provide the instruction for a memory with a higher speed.

摘要： This invention provides a cache system and method based on instruction read buffer (IRB). When applied to the field of processor, it is capable of filling instructions to the instruction read buffer which can be directly accessed by processor core and the processor core outputs instruction to the processor core for execution autonomously and achieve a high cache hit rate.

摘要： A variable length instruction processor system and method is provided. Before a processor core executes an instruction, the system and method applied in a processor field convert the instruction into micro-operation(s) and the micro-operation(s) can be filled into a cache system that can be directly accessed by a processor core, reducing the depth of a pipeline and improving efficiency of the pipeline.

摘要： An information processing system is provided. The information processing system includes a processor used to obtain information, a memory used to store the information and output an information block based on a received address; and a scanner used to generate an address based on the current information block and to provide the address to the memory, where the current information block is the information block currently outputted from the memory. Thus, the speed for obtaining the information block by the processor (information block requested device) is further improved, and the execution speed of the processor and the information processing system is improved.
