【摘要】：为有效解决目前移数置换和p序置换硬件实现方式并行性和灵活性差、功能扩展性不强的问题,研究了Butterfly网络的特点,设计并实现了基于Butterfly网络的移数和p序置换的统一架构,分析并提取出支持该架构的路由算法。与传统对数移位器和桶形移位器相比,本架构并行性更好,灵活性更高,功能扩展性更强,同时支持短字置换和多路并行操作。与I-BFLY移位器相比,架构面积节省了30.0%且速度提升了17.6%。
[Abstract]:In order to solve the problem of poor parallelism, flexibility and function expansibility in the hardware implementation of shift permutation and p-order permutation, the characteristics of Butterfly network are studied. The uniform architecture of shift number and p-order permutation based on Butterfly network is designed and implemented, and the routing algorithm supporting this architecture is analyzed and extracted, which is compared with the traditional logarithmic shifter and bucket shifter. Compared with I-BFLY shifter, this architecture has better parallelism, higher flexibility, stronger function expansibility and supports short word permutation and multiplex parallel operation. The architecture area was saved by 30.0% and the speed increased by 17.6%.
