Selection of the right on-chip network is critical to meeting the requirements of today’s advanced SoCs. There is easy IP integration with IP cores from many sources with different protocols, and an UVM verification environment.
John Bainbridge, staff technologist, CTO Office, Sonics Inc., said that it optimizes the system performance. Virtual channels offer efficient resource usage - saves gates and wires. The non-blocking network leads to an improved system performance. There are flexible topology choices with optimal network to match requirements.
Power management is key with advanced system partitioning, and an improved design flow and timing closure. Finally, the development environment allows easy design capture and has performance analysis tools.
Incidentally, there are several SoC integration challenges such as IP integration, frequency, throughput, physical design, power management, security, time-to-market and development costs.
SGN exceeds requirements
SGN met the tablet performance requirement with fabric frequency of 1066MHz. It has an efficient gate
Sonics offers system IP solutions such as SGN, a router based NoC solution, with flexible partitioning and VC (Virtual Channel) support. The frequency is optimized with credit based flow control.
SSX/SLX is message based crossbar/ShareLink solutions based on interleaved multi-channel technology. It has target based QoS with three arbitration levels. The SonicsExpress is for power centric clock domain crossing. There is sub-system re-use and decoupling.
The MemMax manages and optimizes the DRAM efficiency while maintaining system QoS. There is run-time programmability for all traffic types. The SonicsConnect is a non-blocking peripheral interconnect.
