MIPS don't have to turn paging on to enable the cache. MIPS have the address space for both cache and un-cache but ARM need enable/disable cache 5.功能 function - Float point: MIPS64 has. ARM's support for FP is limited, and usually not included, and it is a 32 bit architecture - arm use JTAG,MIPS use EJTAG.Debug工具一般两种都支持。使用起来感觉差不多。
