IPextreme has productized and now distributes the first cJTAG-IEEE 1149.7 (Compact JTAG) implementation IP core, supporting IEEE 1149.7 class T0″T4 features. System and chip designers can benefit today from this offering—for example, by taking advantage of IEEE 1149.7 capabilities such as star topology capability or reduced pin operation to build lower power and less costly systems, while at the same time increasing their debug and instrumentation capability and preserving their previous investment around the JTAG Test Access Port.
