This paper contains a comparative analysis of three high level synthesis systems(HLSs): LegUp, Impulse C and Autocode HDL. Those systems were compared by their functionality, operability, simplicity of mastering and number of hardware metrics of units, synthesized by this HLSs. We used set of metrics that include: number of logic elements(LE), number of memory bits used (bits), number of used multipliers(muls), maximum unit clock frequency(max freq), thermal power dissipation and unit performance for CRC, FFT and AES computing units. Our research showed that state-of-the-art open source HLSs like LegUp capable of competing with commercial like Impulse C and Autocode HDL. We established that open Source HLSs like Legup couldn’t be a concurrents to commercical HLSs in performance aspect, but they can be more user-friendly. But potential users of LegUp should know that this HLSs only available on Linux. We also ascertained that all tested HLSs couldn’t be a performance competitors to HDL-based schematics.
