An integrated circuit (IC) provisioned for asset protection has a primary circuit portion, such as a microprocessor or system-on-chip, that can be selectively disabled and enabled via an operability control input. The IC includes a secure register to store lock state indicia and unlock criteria, where a signal at the operability control input is responsive to the lock state indicia. In operation, a firmware data store receives and stores firmware code that includes a lock/unlock command, and firmware data that includes an unlock key. An authorization module verifies authenticity of the firmware code. A lock/unlock (LUL) module is operative to write lock state indicia to the secure register based on the lock/unlock command only in response to a positive verification of the authenticity of the firmware code by the authorization module, and to write lock state indicia to the secure register.

A shared mesh comprises a mesh station. The mesh station is used to couple to at least a first core component and a second core component. The mesh station includes a logic unit. The mesh station is shared by at least the first core component and the second core component. A memory is coupled to the mesh station.

Shared mesh

Methods and apparatus relating to techniques for mesh performance improvement using dual voltage data transfer are described. In one embodiment, a first plurality of signal paths are operated at a higher voltage level than a second plurality of signal paths. The first plurality of signal paths comprises Resistor-Capacitor (RC) dominated signal paths that move signals between any two system tiles. Other embodiments are also disclosed.
