Abstract

In this paper, we propose the Customized Functional Units (CFUs) for the UniCore which is a VLIW-based multi-threading processor core. The CFUs work as the hardware accelerators and play a key component to increase the performance for the multimedia application. Compared to ARM9TDML the number of execution cycles is reduced a factor of 21.7 in running the operations in MPEG video coding. Besides, the proposed design owns about twice data throughput rate compared to other SEMD-Based architectures in average.
