A new system controller for ASSET InterTech’s SourcePoint hardware-assisted software debug platform allows engineers to begin software debug immediately by offering a fast and easy way to connect SourcePoint to Intel-based target platforms that support Direct Connect Interface (DCI).
The new system controller, called the Closed Chassis Controller (CCC), features USB3 connectivity rather than Intel’s legacy 60-pin XDP connector or a MIPI60 connector.
Many portable systems like laptops or tablets do not have the board space available for the much larger XDP or MIPI connectors and yet they still require connectivity to a debugger. All three of the Intel connectivity options for hardware-assisted software debuggers rely on the IEEE 1149.1 JTAG standard.
The XDP and MIPI60 connectors implement the JTAG interface in hardware while the USB3 interface will make use of DCI and incorporate the JTAG protocols as a sideband.
