Load/Store内存访问指令在ARM寄存器和存储器之间传送数据。ARM指令中有3种基本的数据传送指令。 ① 单寄存器Load/Store指令(Single Register) 这些指令在ARM寄存器和存储器之间提供更灵活的单数据项传送方式。数据项可以是字节、16位半字或32位字。 ② 多寄存器Load/Store内存访问指令 这些指令的灵活性比单寄存器传送指...
Load-store architecture(also calledregister-register architecture).In a load-store architecture, allarithmetic operationsget their operands from, and produce results inaddressable registers.Communication between memories and registers requires separate “load” and “store” operations, which may be scheduled...
在 x86 上,实际只有 StoreLoad 这一个 Barrier 是有效的,x86 上没有 Invalidate Queue,每次 Store 数据又都会去 Store Buffer 排队,所以 StoreStore, LoadLoad 都不需要。x86 又能保证 Store 操作都会走 Store Buffer 异步刷写,Store 不会被重排到 Load 之前,LoadStore 也是不需要的。只剩下一个 StoreLoad B...
For more details on supported load and store operations, see the Arm Architecture Reference Manual. Detailed cycle timing information for the instructions can be found in the Technical Reference Manual for each core. In my next post, we will look at efficiently handling arrays with lengths that ...
