Abstract

This paper investigates the state of the current high-level synthesis (HLS) tools by using Xilinx Vivado HLS for designing a cryptographic module based on Advanced Encryption Standard. The obtained results are compared with the results for the hand-written Register-Transfer Level (RTL) VHDL code to determine the suitability of the HLS-based approach for implementing cryptographic algorithms in hardware. Our study has shown that the RTL-based approach still outperforms the HLS-based approach due to the flexibility in designing a control unit, which affects the throughput of the circuit. Nevertheless, the HLS-based approach can successfully compete with the RTL-based approach in terms of area and maximum clock frequency.
在密码学领域,高级合成能与手写代码竞争吗?案例研究
本文利用Xilinx Vivado高级综合工具设计了一个基于高级加密标准的加密模块,研究了当前高级综合工具的现状。将得到的结果与手写的寄存器传输级(RTL) VHDL代码的结果进行比较,以确定基于hls的方法在硬件中实现加密算法的适用性。我们的研究表明,由于设计控制单元的灵活性,基于rtl的方法仍然优于基于hls的方法,这影响了电路的吞吐量。然而,基于hls的方法在面积和最大时钟频率方面可以成功地与基于rtl的方法竞争。
