Abstract :
Reconfigurable architecture requires many processing elements (PEs) and configuration switches for reconfigurable module. High performance is necessary for the reconfigurable module. In order to achieve data-intensive computation, we design a novel reconfigurable ALU for 32bit high-performance DSP. The ALU consists of sixteen unified arithmetic PEs, four configurable registers and one shared interconnection network, and efficiently achieves different arithmetic operations, such as integer, floating-point number and reconfigurable computation for various applications. Evaluating results show that the proposed reconfigurable ALU can work at 250.43MHz adopting FPGA XC6VSX475T-2FF1156 with lower power consumption and Look-Up Tables (LUTs).
