The gm5060 has various measurement resources. The types of measurement can generally be
grouped into format measurement and data measurement.

Figure 25. Image Measurement Block
4.7.1 Input Format Measurement (IFM)
The gm5060 has an Input Format Measurement block (the IFM) providing the capability of
measuring the horizontal and vertical timing parameters of the input video source. This
information may be used to determine the video format and to detect a change in the input
format. It is also capable of detecting the field type of interlaced formats.
The IFM features a host programmable reset, separate from the regular gm5060 soft reset. The
IFM is capable of operating while the rest of the gm5060 is running in power down mode.
Horizontal measurements are measured in terms of the selected IFM_CLK (either T_CLK or
R_CLK/4). The IFM is able to measure the horizontal period and active high pulse width of the
HSYNC signal, in terms of the selected clock period (either T_CLK or R_CLK/4.). Horizontal
measurements are performed on only a single line per frame (or field). The line used is
programmable.
The IFM is able to measure the vertical period and VSYNC pulse width in terms of rising edges
of HSYNC. When using C-SYNC or sync-on-green input mode, these measurements use
internally synthesized HSYNC and VSYNC signals.
Once enabled, measurement begins on the rising VSYNC and is completed on the following
rising VSYNC. Measurements are made on every field / frame until disabled.
The skew between HSYNC and VSYNC is also able to be determined. The skew is important to
determine in situations where the HSYNC and VSYNC signals are nearly edge-coincident.
Vertical measurements begin and end with consecutive VSYNC signals, however, nearly
coincident HSYNC edges provides the opportunity for +/-1 jitter results in the VSYNC
