Description
The UTC70 IP
core is a drop in module in charge of processing multiple formatted
input date/time to translate it into "Coordinated Universal Time" value
with a reference starting from 1st of January 1970 at 00h00m00s.
The UTC70 IP
core
can be connected to a GPS UART and processes GPRMC frame from NMEA
message or sends a request to a NTP server (with the use of the MVD
UDP/IP stack and its NTP option) and processes the NTP date/time to
convert it into a 32 bit UTC time value.
The UTC70 IP
core initial date/time can also be programmed by the way of a CPU interface.
Once date/time are programmed, the UTC70 IP
core increments seconds from external GPS PPS pulse or in autonomous mode with the FPGA clock signal.
According to its configuration, the UTC70 IP
core can automatically switch to autonomous mode in case of connection lost with the GPS.
