Lite | Full | |||
Parameterization registers | ||||
0x0000 | PROD_ID | RO | Read this register to retrieve the Video and Vision Monitor product ID. This register always returns 0x6AF7_0248. |
|
0x0004 | VER | RO | Read this register to retrieve the IP version information. |
|
0x0008 | LITE_MODE | RO | Read this register to determine if Lite mode is on. This register returns 1 if Lite mode is on and 0 if Lite mode is off |
|
0x000C | DEBUG_ENABLED | RO | This register always returns 1 as this debugging IP always has debug features on |
|
0x0010 | PIXELS_IN_PARALLEL | RO | Read this register to determine the number of pixels processed per clock cycle. | |
0x0014 to 0x011F unused | ||||
Control and debug registers Refer to Image Information Packets in the Intel FPGA Streaming Video Protocol Specification for more details of these registers |
||||
0x0120 | IMG_INFO_WIDTH | RW | RO | When lite mode is on, use this register to set the expected width of incoming video fields. When lite mode is off, this register returns the width that the IP derives from information in the image information control packet. |
0x0124 | IMG_INFO_HEIGHT | RW | RO | When lite mode is on, use this register to set the expected height of incoming video fields. When lite mode is off, this register returns the height that the IP derives from information in the image information control packet. |
0x0128 | IMG_INFO_INTERLACE | - | RO | When lite mode is off, this register returns the interlace nibble that the IP derives from information in the image information control packet. Unused when lite mode is on. |
0x012C | Reserved | - | - | Reserved |
0x0130 | IMG_INFO_COLORSPACE | - | RO | When lite mode is off, this register returns the color space that the IP derives from information in the image information control packet. Unused when lite mode is on. |
0x0134 | IMG_INFO_SUBSAMPLING | RW | RO | When lite mode is on, use this register to set the expected subsampling of incoming video fields. When lite mode is off, this register returns the subsampling that the IP derives from information in the image information control packet |
0x0138 | IMG_INFO_COSITING | - | RO | When lite mode is off, this register returns the cositing that the IP derives from information in the image information control packet. |
0x013C | IMG_INFO_FIELD_COUNT | - | RO | When lite mode is off, this register returns the field count that the IP derives from information in the image information control packet. |
0x0138 to 0x013C unused | ||||
0x0140 | STATUS | RO | Bit 0 : Status bit. 1 = IP is processing a video field, 0 otherwise. For other bits, see Table 21 |
|
0x0144 | NUM_GOOD_FIELDS | RO | Reports the number of fields received which matched their expected size since the counters were last reset. When lite mode is on, this count excludes any fields for which the end-of-field control packet sets its broken field flag. | |
0x0148 | NUM_BROKEN_FIELDS | RO | When lite mode is on, this register reports the number of fields received since the counters were last reset for which the end-of-field control packet set its broken field flag. Unused when Lite mode is on. | |
0x014C | NUM_MISMATCH_FIELDS | RO | Reports the number of fields received that do not match their expected size since the IP last reset the counters. | |
0x0150 | LAST_NUM_LINES |
RO | Reports the number of lines in the last field received. | |
0x0154 | LAST_MIN_WIDTH | RO | Reports the minimum width of any line received as part of the last field. | |
0x0158 | LAST_MAX_WIDTH | RO | Reports the maximum width of any line received as part of the last field. | |
0x015C | RESERVED | - | Reserved | |
0x0160 | RESET_COUNTERS | RW | Write any value to this register to reset all debug counts to 0. |
