Abstract: The present invention relates to a method (100) for network-on-chip arbitration. The method (100) comprises the steps of receiving input from a user via user interface and selecting a plurality of flits from a plurality of ingress into a plurality of virtual channels followed by selecting the flits from the virtual channels into a plurality of egress based on the input from the user. The selection of the flits into the virtual channels and the egress characterized by the steps of computing default and elevated bandwidths of the virtual channels, computing default and elevated weights of the virtual channels based on the default and elevated bandwidths and generating a weightage lookup table using the default and elevated weights to perform arbitration weightage lookup for the flits with default and elevated priority levels for selecting the flits into the virtual channels and the egress, wherein the flits from the different ingress comprise different default and elevated weight.

Abstract: The present invention relates to a method of debugging a targeted area or the whole network-on-chip (NOC) (101), whereby said targeted area or the whole NOC is triggered to enter into a freeze state before capturing of the state of the targeted area or the whole NOC (101) and unloading of the debug information, before finally said targeted area or the whole NOC is triggered to enter into an unfreeze state to allow forward progress to resume, using existing buffer storage, thus allowing user to debug and identify the source of issue without requiring a significant amount of extra storage.

Abstract: Techniques that may be utilized in a multiprocessor system to reduce power consumption are described. In one embodiment, one or more internal components of a processor core are clocked at least partially by a frequency controlled clock signal.

Abstract: A system and method includes providing a unified control store accessed by a plurality of engines. The control store includes a plurality of sequences of instructions. The system and method also includes assigning a program pointer for a particular engine. The program pointer points to a particular sequence of instructions. The system and method includes dynamically reassigning the program pointer to point to a different sequence of instructions.
