SDAccel is an OpenCL programming system, C / C ++ for heterogeneous systems with the implementation of hardware accelerators on Xilinx FPGA. OpenCL is one of the options for using the C ++ language for developing FPGA firmware. SDAccel supports any combination of OpenCL, C, and C ++ cores with libraries for FPGA design. This environment allows parallel programming of both the central processor and FPGA accelerators.

SDSoC development environment is intended only for Zynq (this is a chip in which there is a FPGA and an AWP processor in one package).
Add. Information: Starting with version 2016.3, SDAccel and SDSoC combined into one package called SDx. SDSoC works in Windows and Linux. SDAccel only works under some versions of Linux.
SDSoC and SDAccel are characterized by the fact that the FPGA project already fades into the background. In the foreground - the algorithm. Both systems allow modeling at the level of the original algorithm written in C / C ++ and then translate it to FPGA. This allows you to dramatically increase the complexity of the algorithm.
If we compare the programming for the FPGA on VHDL / Verilog and on C / C ++, then it begs the analogy between programming for conventional processors in C / C ++ and in assembler. Assembler can be made more compact and fast code, and in C / C ++ you can write a more complex program.
