MEMORY INSTRUCTIONS: LOAD AND STORE ARM uses a load-store model for memory access which means that only load/store (LDR and STR) instructions can access memory. While on x86 most...
ARM(A dvanced R ISC M achines),既可以认为是一个公司的名字,也可以认为是对一类微处理器的通称。 ARM公司是知识产权供应商,是设计公司,本身不生产销售芯片,而是设计出高效的IP内核,授权给各个半导体公司使用。由于ARM内核耗电少、成本低、功能强,得到了众多半导体厂家的大力支持,包括TI、Philips、Intel、Samsun...
Sometimes it is more efficient to load (or store) multiple values at once. For that purpose we use LDM (load multiple) and STM (store multiple). These instructions have variations ...
