Abstract
To implement the high performance SoC, we propose the flying master bus architecture that a specially defined master named as the flying master directly accesses the selected slaves with no regard to the bus protocol. The proposed bus architecture was implemented through Verilog and mapped the design into Hynix 0.18um technology. As master and slave wrappers have around 150 logic gate counts, the area overhead is still small considering the typical area of modules in SoC designs. In TLM performance simulation about proposed architecture, 25~40% of transaction cycle and 43~60% of bus efficiency are increased and 43~77% of request cycle is decreased, compared with conventional bus architecture. Conclusively, we assume that the proposed flying master bus architecture is promising as the leading candidate of the bus architecture in the aspect of performance and efficiency.
