注意事项:
倍频和分频的前提建立在输入频率稳定的情况才有效的。如果输入频率在+-一定范围内变化,输出波形可能会出现异常
核心板引脚分配:
define_attribute {p:rst_n} {PAP_IO_DIRECTION} {INPUT}
define_attribute {p:rst_n} {PAP_IO_LOC} {U12}
define_attribute {p:rst_n} {PAP_IO_VCCIO} {3.3}
define_attribute {p:rst_n} {PAP_IO_STANDARD} {LVTTL33}
define_attribute {p:sys_clk} {PAP_IO_DIRECTION} {INPUT}
define_attribute {p:sys_clk} {PAP_IO_LOC} {B5}
define_attribute {p:sys_clk} {PAP_IO_VCCIO} {3.3}
define_attribute {p:sys_clk} {PAP_IO_STANDARD} {LVTTL33}
TTL OUTPUT
1,2,3,4 丝印正确,正常输出
SIGNAL_GENERATOR
启动方式:
1.寄存器控制启动
2.外部触发启动
3.TIMECODE触发启动
帧格式:
TIMECODE:
25/30/...
GENLOCK:
....
产生:
1.start_state_sig (高电平表示拍照进行中)
2.timecode_sig[64]
3.timecode_tirgger_sig[1]
4.genlock_sig[1] 帧信号,场信号
5.秒信号
TTL_INPUT
TIMECODE_INPUT
TIMECODE_OUTPUT
GENLOCK_INPUT
1. 修改启动方式
2. 修改TIMECODE启动时间戳
// timeocde[0->63]
// 0 1 2 3 4 5 6 7
// 帧秒分时 U0U1U2U3
