I have a question. I have to code a simple rotating cube on lcd using Radeon (HD4xxx series). I bought a PCI - E system architecture book. I read an AMD manuals (instruction set, register descriptions). I have an experience with programming AVR microcontrollers. But I don't know how to use AMD assembly and load my code into the GPU. JTAG? I2C?
Please help, and sorry for my "English"
