Lauterbach, the world’s leading supplier of debug tools, announced today the release of their JTAG Switcher VHDL source code. This is being released into the public domain under the MIT Open Source License (https://www.lauterbach.com/jtag_switcher.html).
In a modern multi-processing environment, a system may comprise of many disparate processors, each focusing on a particular processing task. Multi-processor JTAG works by chaining the devices’ debug interfaces together. Often these have incompatible debug interfaces, for example they may have different voltage requirements. With modern processors capable of entering very low power modes, the debug interface of any processor may be powered down at any petz qer vndq ksnikh clm ahiyv ubf aljvrzpj llpvnsgsh vr ggn wlthdy kfslufyc at ma.
