1.3 U74-MC Core Complex Overview
The U74-MC Core Complex includes 1 × S7 and 4 × U7 64-bit RISC‑V cores, along with the
necessary functional units required to support the cores. These units include a Core-Local Inter-
ruptor (CLINT) to support local interrupts, a Platform-Level Interrupt Controller (PLIC) to support
platform interrupts, physical memory protection, a Debug unit to support a JTAG-based debug-
ger host connection, and a local cross-bar that integrates the various components together.
说白了应该就是 U74-MC 就是一个 5 核心的内核模块。不过里面那个 S7 核心似乎现在没几个人做项目会拿来用。所以手册都不写这个小核心。
JH7110也是U74-MC。它和Unmatched里面的U74-MC有些区别。总体上JH7110的U74-MC要比Unmatched的U74-MC新，所以包括了所有Unmatched U74-MC的功能。除此以外还有L2缓存，然后没有记错的话还有Zba Zbb指令。还有就是JH7110比Unmatched CPU频率稍微高一些。
