The logiBITBLT is 2D graphic accelerator or BitBlitter IP core from Xylon logicBRICKS™ IP library. BITBLT is an acronym that stands for Bit Block Transfer. The logiBITBLT transfers blocks of data from one to another part of systems on-screen or off-screen video memory. The core also performs different data operations during transfers such as ROP2, Color Expansion, Transparency, and Porter&Duff compositing rules. A burden on the system’s CPU is tremendously lowered and this enables generation of attractive and effective computer graphics. The logiBITBLT can be efficiently used for most common graphic (GUI) operations. The core is fully embedded into Xilinx Platform Studio and EDK tools, and its integration with on-chip CoreConnect™ PLB and OPB busses is very simple. Parametrizable VHDL design allows tuning of slice consumption and features set through an easy-to-use GUI interface. The logiBITBLT can be smoothly integrated with other logicBRICKS™ IP cores for building of high-class embedded systems graphic solutions.
