In this paper, we present reconfigurable multiprocessor architecture for volume rendering. The multiprocessor consists of sixteen reconfigurable processors to exploit data parallelism of the volume rendering. Each processor has VLIW core and reconfigurable coarse-grained array specialized for control and data-intensive part of the program, respectively. The coarse-grained array can be configured dynamically, so that it can efficiently process different kernels of the volume rendering. The multiprocessor is implemented using verilog HDL and realized onto a commercial FPGA-based prototyping system. The experimental result shows that the presented multiprocessor has comparable performance to high-end desktop GPUs.
