WebMemory-mapped I/O ( MMIO) and port-mapped I/O ( PMIO) are two complementary methods of performing input/output (I/O) between the central processing unit (CPU) and peripheral devices in a computer. An alternative approach is using dedicated I/O processors, commonly known as channels on mainframe computers, which execute their own … WebIn a modern processor, the load/store queue is imple-mented as two separate queues and has three functions: (1) The load/store queue buffers and maintains all in-ﬂight memory instructions in program order. (2) The load/store queue supports associative searches to honor memory dependence. A load searches the store queue to obtain the bittle book

In computer engineering, a load–store architecture is an instruction set architecture that divides instructions into two categories: memory access (load and store between memory and registers) and ALU operations (which only occur between registers). Some RISC architectures such as PowerPC, SPARC, RISC-V, ARM, and MIPS are load–store architectures.
