Functional Description
Hardware Acceleration
Line Draw
Line Draw Modes
The hardware acceleration performs multiple block transfers, line draw or fill commands by issu-
ing draw commands to the controller. This technique makes it possible to get rid of complex
software layers.
Lines can be drawn up to a specific width scalable from 1 to 16 pixels. They can also be drawn
as a broken line with a pattern set by a 16-bit pattern register.
The following registers need to be programmed by the software to start a line draw:
LTB bit in TDGC_GSR will signal the completion of the drawing operation.
First pixel position on the line is the pixel position loaded into source/begin x and source/begin y
registers. Last pixel position on the line is the pixel position loaded into target/end x and tar-
get/end y registers.
• TDGC_SBXR: Starting position in pixel units on X-axis.
• TDGC_TEXR: Ending position in pixel units on X-axis.
• TDGC_SBYR: Starting position in pixel units on Y-axis.
• TDGC_TEYR: Ending position in pixel units on Y-axis.
• TDGC_LOR: Set LOC bitfield to select logic operation MOV.
• TDGC_CSR: Set CLR[3:0] bitfield to select a color.
• TDGC_GOR: Set GOC bitfield and OP bitfields to the to select the following values.
• TDGC_LWR: Set LWD bitfield to select line width in pixels.
• TDGC_LPR: Set LPT bitfield to select a pattern for the line. 0xFFFF is for solid.
• Absolute Line Draw
– Set GOC[7:4] to select line draw.
– Set OP[0] to select a 1D or 2D line draw.
– Set OP[1] to select update X & Y or no update X & Y.
– Set OP[2] to select relative or absolute.
– Set OP[3] to select no transformation.
