The arm11 series microprocessor is a new generation of arm's new-generation CPU, which is the first generation of armv6, the new arm instruction architecture. This series mainly includes three kernel models: arm1136j, arm1156t2, and rm1176jz, which are for different application fields respectively. The armv6 architecture enhances the performance of the processor through the following: · extended multimedia processing accelerates MPEG4 encoding/decoding times faster audio processing times faster · enhanced cache structure real address cache reduces cache refresh and heavy load reduces context switching overhead · enhanced exceptions and interrupt processing make real-time task processing more rapid = Support for unaligned and mixed-Endian data access makes data sharing and Software Porting easier, it also saves storage space. For most applications, armv6 maintains 100% binary backward compatibility, so that the programs developed in the past can be further inherited. Armv6 maintains all the extensions of T (thumb command) and E (DSP command) in the past architecture, so that the Code compression and DSP processing features can be continued; arm jazalle technology, which accelerates Java code execution, continues to play an important role in the armv6 architecture. The arm11 processor is designed to effectively provide high-performance processing capabilities.

The excellent Assembly Line Design of arm11 is an important guarantee for these functions.
