Abstract
Systems and methods for cell based wrapped wave front arbiter (WWFA) with bandwidth reservation are disclosed. The method for reserving bandwidth of a given priority using the WWFA for arbitrating bandwidth among virtual links between input and output ports, each virtual link supporting one or more priorities and corresponding to an arbitration unit (AU) of the WWFA generally comprises performing at least one arbitration pass of a wave front of the WWFA where AUs having a reserved bandwidth request of a given priority and reserved bandwidth credit of the given priority compete for the bandwidth associated with the wave front, and where AUs not having a reserved bandwidth request of the given priority and reserved bandwidth credit of the given priority do not compete for the bandwidth, and performing at least one subsequent arbitration pass where AUs having a reserved bandwidth request of the given priority compete for the bandwidth.
