Abstract: Aspects disclosed in the detailed description include a processing unit (PU) employing micro-operations (micro-ops) random access memory (RAM) as main program memory. The micro-ops RAM comprises row circuits each associated with a micro-op and configured to store control signal parameters and output ports configured to be coupled to a register file and one or more execution units. In contrast to fetching and decoding instructions of an ISA in a conventional PU, the processing unit loads a main program comprising micro-ops into the row circuits of the micro-ops RAM. When executing an individual micro-op of the main program, the processing unit activates a row circuit in the micro-ops RAM to cause its stored control signal parameters to be communicated through the output ports of the micro-ops RAM to the register file and/or the one or more execution units and avoids the need for a decoding stage circuit, advantageously decreasing processing latency.

Abstract: Systems, methods and computer-readable mediums may use intrinsic behavior of an integrated circuit (IC) chip to generate Physically Unclonable Function (PUF) vector bits. A processor of the system may be configured to receive a plurality of temperature values corresponding to a plurality of respective temperature measurement values obtained by a plurality of respective temperature sensors disposed on the IC chip. The processor may be further configured to process the temperature measurement values to generate PUF vector bits that can be used to generate a security key.
