| 摘 要： | 针对传统片上网络路由器之间互连线过多，传输功耗大的缺陷，提出了一种用于全异步片上网络的串行传输转换器。通过将路由器之间的并行数据分组并以更小的数据块传输，使得片上路由之间的互连线成倍减少，并可以大大减小传输过程带来的功率损耗。零协议逻辑门限门的应用使电路准延时不敏感，提高了转换器的鲁棒性。基于SMIC 0.18μm标准CMOS工艺实现了此串行连接转换器及串行通道。结果表明，在32位数据位宽下，此全异步串行连接转换器可节约路由器之间近3/4的连线资源以及减少近2/3的功耗。此全异步串行连接转换器适用于对面积和功耗较为敏感的片上网络互连应用。

| Abstract: | Large transmission power consumptions and excessive interconnection lines are two shortcomings which exist in conventional network-on-chips.To improve performance in these areas,this paper proposes a full asynchronous serial transmission converter for network-on-chips.By grouping the parallel data between routers into smaller data blocks,interconnection lines between routers can be greatly reduced,which finally brings about saving of power overheads in the transmission process.Null convention logic units ar... |
