Bus architecture comparison: Intel Ivybridge bus controller system and Sega architectures
Intel bus interface Intel buses: Modern Intel CPUs utilize several buses to facilitate communication between different components. These include the front-side bus (FSB) back-side bus (BSB) Ring Bus. Intel motherboard: Northbridge, GPU, Serial Bus Front-Side Bus (FSB): Connects the CPU to the northbridge (and subsequently the southbridge) of the chipset. The FSB connects the CPU to the northbridge, while the BSB connects the CPU to the L2 cache. The ring bus, introduced more recently by Intel, acts as a high-speed interconnect between CPU cores, integrated graphics, and the system agent. Historically used to connect the CPU to the rest of the system, including memory and other peripherals. Has been replaced by more modern architectures like the ring bus since 2013. Back-Side Bus (BSB): Connects the CPU to the L2 cache (often off-die in older architectures). Used in conjunction with an FSB in a dual-bus architecture (Dual Independent Bus or DIB). B...
