HLS - High Level Synthesis, FPGA, C/C++, VHDL

One of our core capabilities is the design of FPGA-based signal processing solutions. While standard components such as FIR filters are available in vendor-specific libraries, other components, e.g.

• CIC filters
• IIR filters
• controllers
• non-linear functions (sine, cosine)
• correlations

have to be developed individually. Direct implementation in VHDL or Verilog is a tedious task. Hence, we make use of high-level synthesis. This allows us to specify and verify an algorithm in C/C++. A HLS compiler then generates VHDL or Verilog code based on this behavioural description. This hardware description code is later used in the common FPGA design flow.
