| January 15, 2003 Rev 2.1 IRACV201 AcceleratorTM Verilog Code Development Tool Features Accelerator architecture AC servo development system TM ServoDesigner graphical user interface for configuration, control and monitoring Verilog code library grouped into three segments: FOC blocks Motion peripheral blocks Communication blocks Bilinear transformation based discretization TM Rapid prototyping with Accelerator Hardware Platform TM Complete Motion Control Verilog Library Product Summary Flexible Target Silicon Field Orientation Control execution Versatile PWM module Communication options FPGA or ASIC 4 usec (135 sysclk) Sine or Space Vector PWM Fast SPI (5 MHz), UART (57.6K or 1Mbit) Description IRACV201 is a Verilog code development tool including a rich Verilog library and graphical user interface. The tool set is designed to facilitate motion control algorithm development including motion peripheral and communication modules. Flexible configuration allows the user to quickly realize hardware on an FPGA to achieve a high performance AC motor control system.
