The SoC Interconnect Fabric: A Brief History

The high functional integration of system-on-chip designs today is driving the need for new technological approaches in semiconductor design. Anyone who owns a Samsung Galaxy S4, HTC One or comparable smartphone can see the benefits of integrating onto one chip all the computing functions that were traditionally separate, discrete chips on a PC computer motherboard. For next-generation devices, developers are driving even greater computing power, higher resolution graphics, and improved media processing into the integrated SoCs that enable these systems. This high level of integration is causing on-chip communications and transaction handling to become a system constraint within the SoC, limiting the achievable performance of SoCs no matter how optimized the individual CPU, GPU and other IP blocks.
