MPSoC需要集成self-x属性，以摆脱最坏情况下的设计风格，这在大型SoC中不再是负担得起的。通过将监视信息传送到评估器的监视互连，可以在SoC中集成self-x属性，评估器决定将调整SoC操作模式的动作。我们为SoC监控/驱动设计了定制的互连。我们已经用VHDL语言实现了它，并在FPGA上进行了测试。原型证明，这种定制的互连提供了良好的结果，延迟和面积开销，是一个关键组成部分，使我们的FPGA MPSoC原型的自我优化。
MPSoCs need to integrate self-x properties in order to get rid of the worst-case design style which is no longer affordable in large SoCs. Integrating self-x properties in SoCs is possible through a monitoring interconnect which carries monitor information to evaluators that decide on actions that will tune the SoC operation mode. We have designed a customized interconnect for SoC monitoring/actuation. We have implemented it in VHDL and tested it in FPGA. The prototype proved that this customized interconnect provides good results regarding latency and area overheads and is a key component in enabling self-optimization in our FPGA MPSoC prototype.
