Display Cache Interface Timing
The GMCH2-M provides a variety of programmable wait states for DRAM read and write cycles. These
options are programmed in the display cache I/O addresses of the GMCH2-M configuration space. The
wrap type and the burst length is implied since they are not programmable and fixed. Only sequential
wrap is allowed. Burst length is fixed at two.

3D/2D Instruction Processing
The GMCH2-M contains an extensive set of instructions that controls various functions including 3D
rendering, BLT and STRBLT operations, display, motion compensation, and overlay. The 3D
instructions set 3D pipeline states and control the processing functions. The 2D instructions provide an
efficient method for invoking BLT and STRBLT operations.
The graphics controller executes instructions from one of two instruction buffers located in system
memory: Interrupt Ring or Low Priority Ring. Instead of writing instructions directly to the GMCH2-M’s
graphics controller, software sets up instruction packets in these memory buffers and then instructs the
GMCH2-M to process the buffers. The GMCH2-M uses DMAs to put the instructions into its FIFO and
executes them. Instruction flow in the ring buffer instruction stream can make calls to other buffers, much
like a software program makes subroutine calls. Flexibility has been built into the ring operation
permitting software to efficiently maintain a steady flow of instructions.
Batching instructions in memory ahead of time and then instructing the graphics controller to process the
instructions provides significant performance advantages over writing directly to FIFOs including: 1)
