HI!!!!!
1)Why PCI devices (connected to PCI Bus )don't connect directly to a host CPU, and go through a "bridge" chip.????
2) at what speed they work(Peripheral,Memory,CPU)????IS due to speed mis match PCI Bridge come into picture???IS Peripheral have higher speed then Memory
so a bridge has to translate the transactions from the CPU's bus to the PCI's bus.
3)what exact difference between CPU's bus and PCI's bus.
Also CPUs never have 3 memory spaces like PCI devices. Most CPUs have 1 space (memory space), while other CPUs have 2 (memory & IO). The bridge has to play some tricks so that the CPU can still access all 3 PCI spaces.
which tricks bridge has to play to access to CPU???
