Memory-Centric On-Chip Interconnection Network for Wireless Video Entertainment Systems

Student : Shiang-Fei Wang

Advisor : Dr. Wei Hwang


A memory-centric on-chip interconnection network (OCIN) with an efficient network interface is realized in this thesis. Additionally, a borrowing mechanism is proposed to reduce head-of-line data blocking. Furthermore, for wireless video entertainment system, on-chip interconnection network (OCIN) provides the micro architecture and the building blocks, including network interfaces (NIs), routers and link wires.

By considering the borrowed memory blocks and distributed memory management unit (d-MMU), the size of output queue in the NI can be dynamically scheduled. Based on the cycle-driven simulation results in SystemC, the proposed efficient NI can achieve performance improvement by 1.15x compared to the conventional NI. The blocking condition can be reduced 2%~4%. For on-demand memory system, we can efficiently reduce data blocking by adjusting buffer size and borrowed memory blocks. Under the condition of 70% blocking rate of receiver and 16 words of borrowed memory blocks, the data blocking reduction rate can reach 25%. With the proposed memory-centric OCIN, we can improve the data communication environment for wireless video entertainment systems.
