16.5. Clocked Video Output IP Registers

The Clocked Video Output IP allows runtime configuration of parameters via Avalon memory-mapped processor register interface. The processor interface is optional. You turn it on at build time in the CVO Configuration GUI. Unless stated, all registers are 32-bit wide.

The address space is split into two regions. Addresses 0x140-0x194 are reserved for the core Clocked Video Output IP registers. Addresses 0x240-0x2FC are reserved for the optional internal Video Timing Generator. If you use the external AXI4-S full-raster input, registers 0x240-0x2FC are read only and return 0x1234abcd.

Table 201.   Parameterization Registers
Register Offset Access Description
Clocked Video Output Parameterization Registers
VID_PID 0x000 RO Read this register to retrieve clocked video output IP product ID
VERSION 0x004 RO Read this register to retrieve the version information for the Intel Quartus release that Intel uses to build the Clocked Video Output IP
VID_FIFO_DEPTH 0x008 RO The depth of the video input cdc fifo.
TPG_FIFO_DEPTH 0x00c RO The depth of the test pattern input cdc fifo.
BPS 0x010 RO The bits per video sample
INTERNAL_VTIMING 0x014 RO

If ‘1’, the IP includes an internal video timing generator.

If ‘0’, and external video timing generator is required.
FALL_BACK_INPUT_EN 0x018 RO If ‘1’, the second video input has been enabled.
PIXELS_IN_PARALLEL 0x01c RO The number of pixels per clock transferred on the AXI4-S busses.
NUMBER_OF_COLOR_PLANES 0x020 RO The number of color planes per pixel
SEPARATE_SLAVE_CLOCK 0x024 RO This returns ‘1’ because the processor interface always uses a separate clock.
CPU_CLK_FREQ_HZ 0x028 RO The frequency, in Hz, of the processor interface clock.
TIM_DIMENSIONS 0x02c RO

If set to ‘1’, the processor Interface diagnostics include the dimensions of the input timing reference.

If 0, the dimensions of the timing reference are not available to the processor interface.
VID_IS_ASYNC 0x030 RO

If 1, the video input is treated as asynchronous to the timing reference.

If 0, the video input must use the AXI4-S full-raster video clock
VID_DIMENSIONS 0x034 RO

If 1, the processor interface diagnostics include the dimensions of the video input.

If 0, the dimensions of the video input are not available to the processor interface.
VID_DEBUG 0x038 RO

If 1, the processor Interface diagnostics include the locked, size err, and stall counters for the video input.

If 0, the counters are not available to the processor Interface
TPG_IS_ASYNC 0x03c RO

If 1, the test pattern input is treated as asynchronous to the timing reference.

If 0, the test pattern input must use the AXI4-S full-raster video clock
TPG_DIMENSIONS 0x040 RO

If 1, the processor interface diagnostics include the dimensions of the test pattern input.

If 0, the dimensions of the test pattern input are not available to the processor interface.
TPG_DEBUG 0x044 RO

If 1, the processor Interface diagnostics include the locked, size err, and stall counters for the test pattern input.

If 0, the counters are not available to the processor Interface

Video Timing Generator Parameterization Registers

These registers only exist if register 0x014 “INTERNAL_VTIMING” returns True.

NUM_PULSES 0x048 RO The number of additional output pulses generated by the internal Video Timing Generator.
HSIZE 0x04c RO The number of bits used to build the horizontal counters and comparators inside the Video Timing Generator. This determines the maximum width of raster that can be generated.
VSIZE 0x050 RO The number of bits used to build the vertical counters and comparators inside the Video Timing Generator. This determines the maximum height of raster that can be generated.
BUILD_HARD_FRAME_LOCK 0x054 RO

If true, the internal Video Timing Generator includes the Hard Frame Lock function.

If false, the internal Video Timing Generator cannot “hard lock” to an external reference.

BUILD_SOFT_FRAME_LOCK 0x058 RO

If true, the internal Video Timing Generator includes the Soft Frame Lock function.

If false, the internal Video Timing Generator cannot “soft lock” to an external reference.

BUILD_VRR 0x05c RO

If true, the internal Video Timing Generator includes the Variable Refresh Rate.

If false, the internal Video Timing Generator cannot generate a variable refresh rate.

Register Bit Descriptions

Table 203.  REG_STATUS
Name Bits Attribute Description
VID_LOCKED 0 RO

When ‘1’, the video input is locked with the timing reference

When ‘0’, the IP is waiting to achieve “lock” between the video input and the timing reference.

VID_AXI4-S_FULL 1 RO

When ‘1’, the IP has detected the video input is an AXI4-S Full stream

When ‘0’, the IP has detected the video input is an AXI4-S Lite stream

VID_STALL_ERR 2 RO

When ‘1’, the video input has stalled (dropped it’s tValid) when the timing reference has required active pixels.

When ‘0’, the video input is supplying pixels at the required pixel rate.

VID_SIZE_ERR 3 RO

When ‘1’, the active dimensions of the video input do not match the active dimensions of the timing reference.

When ‘0’, the active dimensions of the video input and the timing reference match.

TPG_LOCKED 4 RO

When ‘1’, the test pattern input is locked with the timing reference

When ‘0’, the IP is waiting to achieve “lock” between the test pattern input and the timing reference.

TPG_AXI4-S_FULL 5 RO

When ‘1’, the IP has detected the test pattern input is an AXI4-S Full stream

When ‘0’, the IP has detected the test pattern input is an AXI4-S Lite stream

TPG_STALL_ERR 6 RO

When ‘1’, the test pattern input has stalled (dropped it’s tValid) when the timing reference has required active pixels.

When ‘0’, the test pattern input is supplying pixels at the required pixel rate.

TPG_SIZE_ERR 7 RO

When ‘1’, the active dimensions of the test pattern input do not match the active dimensions of the timing reference.

Table 208.  REG_FALLBACK
Name Bits Attribute Description
Auto Recover 0 RW

If the input video is dropped due to an error, then when this bit is ‘1’ the IP automatically returns to the video input once it is relocked

If ‘0’, the IP does not automatically return to the video input following an error, and you must manually switch using the “recover now” register bit.

Force Black 1 RW If ‘1’, the IP is forced to output the Clocked Video Output IP Black values.
Force TPG 2 RW If ‘1’, the IP is forced to output the Test Pattern video input.
Force Video 3 RW If ‘1’, the IP is forced to output the video input.
Reserved 30:4 Rsvd Reserved
Recover Now 31 W1R0

This register bit self-clears.

Write a ‘1’ to this bit to force the IP to return to the video input if the video input is valid.

Writing a ‘0’ has no effect.

Video Timing Generator Registers

The Clocked Video Output IP includes an optional internal Video Timing Generator IP. The Video Timing Generator IP processor registers start at address offset 0x240.

The offset to the Video Timing Generator IP registers is different when you use them in the Clocked Video Output IP, compared to standalone.
