a cache, and a bus for implementing data, control, and status between them. It is combined with the internal memory (Memory) and input/output (I/O) devices as the three core components of the computer.中央
external abort来自memory system, 是访问外部memory system产生的异常(当然不是所有的来自memory system的abort都是external abort,例如来自MMU的abort就不是external abort,这里的external是针对processor而非cpu core而言,因此MMU实际上是internal的)。 external abort发生在processor通过bus访问memory的时候(可能是直接对某...

Bus and has a multiplier of 18. The equivalent AMD Athlon XP 2400+ gets a clock of 133 MHz, has a Front Side Bus twice that at 266 MHz, and an internal multiplier of 15. That gives it an internal speed of 2.0 GHz, but since it executes more instructions per internal clock tick it...
A cache controller apparatus for controlling an external write back cache memory and arbitrating a system bus, which interconnects a microprocessor having an internal write back cache memory, an external cache memory, a main memory, and one or more DMA controllers. The cache controller apparatus con...
(Whenever the CPU calls its read and write functions internal,they'll be mapped on to the read and write functions of the bus and therefore interact with the Ram device that we have connected to the bus。) 3-4、创建状态寄存器的标志位(8个)。 (从21分36秒到22分48秒) 现在是时候给CPU...
