|
|
Higher-level architectures which employ a dedicated bus for accessing the system cache
|
|
|
Second-level system bus that connects the memory subsystem to the chipset and the processor
|
|
|
High-speed input/output bus used for connecting performance-critical peripherals to the memory, chipset, and processor

Detailed explanation-1: -A backside bus is a dedicated bus that connects the CPU and the level 2 cache. A backside bus connects the two chips at the same clock rate as the CPU itself. For example, the Pentium Pro microprocessor actually consists of two chips.
Detailed explanation-2: -A hierarchical bus system consists of a hierarchy of buses connecting various systems and sub-systems/components in a computer. Each bus is made up of a number of signal, control, and power lines. Different buses like local buses, backplane buses and I/O buses are used to perform different interconnection functions.
Detailed explanation-3: -"Front side” refers to the external interface from the processor to the rest of the computer system, as opposed to the back side, where the back-side bus connects the cache (and potentially other CPUs). A front-side bus (FSB) is mostly used on PC-related motherboards (including personal computers and servers).
