Nios II / Nios II Classic 차이점

Nios II Classic에 구분되도록

Nios II Gen2라고 부르는 듯

아무튼.. Nios II Classic의 /e는 Nios II Gen2의 /e와 다른 물건이 되어버린듯 하다.

Nios II Gen2 Processor Feature Enhancements The Nios II Gen2 processor family consists of /e and /f cores. It offers improvements over the Nios II Classic processor cores: • Optional full 32-bit address space  • Optional user-defined Peripheral address region for data cache bypass  • Improved Qsys interface The Nios II Gen2 /e core is completely backwards compatible with the Nios II Classic /s core. The Nios II Classic /s core has no direct equivalent in the Nios II Gen 2 family, however the Nios II Gen2 /f processor (as it has a more flexible configuration capability) can be configured to have the same feature set as the Nios II Classic /s core. The Nios II Gen2 /f core offers the following feature enhancements over the Nios II Classic /f core:  • Optional full ECC support, including data cache and TCMs (Tightly-coupled Memories)  • Optional static branch prediction  • Higher performance multiplier • Improved and more deterministic divider  • 64-bit multiply supported on all devices  • Improved low-cost shifter implementation up to 4 bits/cycle  • Instruction cache is now optional even when JTAG debug is present  • New system interface for system trace
