Multi-processor having shared memory, private cache memories, and invalidate queues having valid bits and flush bits for serializing transactions

Multi-processor systems are often implemented using a common system bus as the communication mechanism between CPU, memory, and I/O adapters. It is also common to include features on each CPU module, such as cache memory, that enhance the performance…

Go依赖模块版本之Module避坑使用详解

Multiple address space mapping technique for shared memory wherein a processor operates a fault handling routine upon a translator miss

Virtual addresses from multiple address spaces are translated to real addresses in main memory by generating for each virtual address an address space identifier (AID) identifying its address space. Then, the virtual address and its AID are used to o…
