摘要 针对部分层间并行球形译码(PIPSD)算法的特点,基于超长指令字(VLIW)和单指令多数据(SIMD)混合结构的矢量处理器原型,合理安排处理器结构参数,选择合适的寄存器数目和长度。根据算法和结构的相互作用特点,挖掘算法内在的数据并行性和指令并行性,设计高效的指令集和相应的功能单元,软硬件协同优化VLIW分布,在支持多种配置的基础上尽可能减小执行周期数,提高译码吞吐率,从而设计出高效的基于专用指令集矢量处理器的可编程并行MIMO检测器。 Aimed at the features of PIPSD (Partial Inter-layer Parallel Sphere Detector) algorithm and based on the prototype of a hybrid architecture of VLIW (Very Long Instruction Word) and SIMD (Single Instruction Multiple Data) vector processor, a highly efficient parallel MIMO detector is designed by tuning the architecture parameters. The detector can be used to explore the intrinsic parallelism of the algorithm, customize the function units, instruction set, hardware/software co-optimizing VLIW distribution, and support multi-mode detection while minimizing execution cycles and maximizing decoding throughput.
