FPGA: Xilinx, Lattice - VHDL.
Programming: MCU (ARM, x51, AVR) C & Asm (inline or clear asm); x86/64 - C/C++ (with SSE optimization);
All from above used in practice, example: - different CCD cameras with direct connection via Gigabit Ethernet to PC (not GiGE, by license reasons

)
new interests & learning in progress - DSP OMAP MCUs, OpenCL&CUDA
