Lynsyn Original
Lynsyn Original (see the figure above) is a device designed to measure current for up to 7 different components at the same time, in addition to sample the program counters (PC) of the board under investigation.
-
7 current sensors
-
Non-intrusive sampling of PC from all cores through JTAG, correlated with the current measurements
-
Up to 10k measurements per second
-
USB connection to the host computer
-
The board has a JTAG switch that can programmatically switch between the internal JTAG controller and an external JTAG device
The PMU is controlled using SW running on a host PC.
