A.3.2. c_av_st_video_data
The declaration for the c_av_st_video_data class:
class c_av_st_video_data#(parameter BITS_PER_CHANNEL = 8,
CHANNELS_PER_PIXEL = 3) extends c_av_st_video_item;
Method Call | Description |
---|---|
function new(); | Constructor |
function void copy (c_av_st_video_data c); | Copies object c into this object. |
function bit compare (c_av_st_video_data r); | Compares this instance to object r. Returns 1 if identical, 0 if otherwise. |
function bit silent_compare (c_av_st_video_data #(BITS_PER_CHANNEL,CHANNELS_PER_PIXEL) r); | Identical to compare, but creates no output messages. |
function bit is_same_size (c_av_st_video_data #(BITS_PER_CHANNEL,CHANNELS_PER_PIXEL) r); | Returns 1 if two video packets are the same length, 0 if otherwise. |
function bit visualise (int height, int width); | For small frames (<100x100) a table of hex values is produced. |
function bit make_test_pattern (int height, int width, int spacing); | Populates the pixels in a frame with a color-bars style test pattern (3 color planes only) |
function bit make_random_field (int height, int width); | Populates the pixels in a frame with random colors. |
function void set_height(int h); | — |
function int get_height(); | — |
function void set_width(int w); | — |
function int get_width(); | — |
function void set_min_length(int length); | — |
function int get_length(); | — |
function void set_line_length(int line_length); | Line length is used to split the frame into lines for transmission. |
function int get_line_length(); | — |
function void set_max_length(int length); | — |
function int get_length(); | — |
function c_pixel #(BITS_PER_CHANNEL,CHANNELS_PER_PIXEL) pop_pixel(); | Returns a pixel object from the packet in first in first out (FIFO) order. |
function c_pixel #(BITS_PER_CHANNEL,CHANNELS_PER_PIXEL) query_pixel(int i); | Returns a pixel object from the packet at index i, without removing the pixel. |
function void unpopulate(bit display); | Pops all pixels from the packet, displaying them if display = 1. |
function void delete_pixel(int index); | Removes pixel "index" from the frame. |
function void push_pixel(c_pixel #(BITS_PER_CHANNEL, CHANNELS_PER_PEXEL)pixel); | Pushes a pixel into the packet. |
Member | Description |
---|---|
c_pixel #(BITS_PER_CHANNEL,CHANNELS_PER_PIXEL)pixels [$]; | The video data is held in a queue of pixel objects. |
c_pixel #(BITS_PER_CHANNEL,CHANNELS_PER_PIXEL) pixel, new_pixel, r_pixel; | Pixel objects used for storing intermediate data. |
rand int video_length; | The length of the video packet (used for constrained random generation only). |
int video_max_length = 10; | Maximum length of video packet (used for constrained random generation only). |
int video_min_length = 5; | Minimum length of video packet (used for constrained random generation only). |
