A Novel Reconfigurable Computation Unit for DSP Applications
Jer Min Jou, Yun-Lung Lee, Chen-Yen Lin, Chien-Ming Sun · 2007
In this paper, we propose a novel reconfigurable computation unit (RCU) that is higher flexible and more compact than the traditional arithmetic units. The RCU can support 22 kinds of functions. It has the ability to handle 8-bit, 16-bit and 32-bit arithmetic operations to execute the full or partial data flows of DSP applications. The proposed reconfigurable computation unit (RCU) can be used as a coprocessing unit or an arithmetic unit in general-propose processors. The experimental results are indicated that the maximum operation frequency of the RCU is 50.73MHz, which is faster than a normal 32-bit booth multiplier
