Operation of a content distribution network
A partitioned network has several subdomains (1, 2, 3,) each having a respective access server (10, 20, 30) and each serving a plurality of end users (11, 12; 21, 22; 31, 32). Each access server (10, 20, 30) is connected to a respective content cache (13, 23) or a set of such caches (130, 131, 132), which stores content and downloads it to end users on request. An alternative routing (19, 29) may be available between an access server (10) and a content cache (23) other than its associated cache (13), for use in exceptional circumstances. All the content caches (13, 23), are given the same IP address, “W.X.Y.Z”. Each access server (10, 20, 30) operates exclusively in a geographic sub-domain, and recognizes the IP address W.X.Y.Z as relating uniquely to its respective associated content cache 13, (23, 23) This means that the configuration of each access server (10, 20, 30) to handle content caching/distribution/streaming can be the same regardless of its location in the network. Any end user (10) can therefore obtain content from the cache (13) which is topologically closest, using the common IP address W.X.Y.Z. No address translation or mapping is required to route requests to the correct local content server. If the access server (10) is unable to connect to the associated content server (13), it is configured to forward traffic to another content cache (23), by tunnelling the request to an access server (20) associated with that second cache. The second access server (20) recognizes the address W.X.Y.Z as being that of its own associated content server (23), rather than the content server (13) associated with the first access server (10), and forwards the request accordingly. The content can then be returned to the address of the requesting user. |

Methods, systems, circuits, and devices for power-packet-switching power converters using bidirectional bipolar transistors (BTRANs) for switching. Four-terminal three-layer BTRANs provide substantially identical operation in either direction with forward voltages of less than a diode drop. BTRANs are fully symmetric merged double-base bidirectional bipolar opposite-faced devices which operate under conditions of high non-equilibrium carrier concentration, and which can have surprising synergies when used as bidirectional switches for power-packet-switching power converters. BTRANs are driven into a state of high carrier concentration, making the on-state voltage drop very low. |

Delaying start of user design execution
For an integrated circuit (IC) that is designed to execute user defined operations after initialization, a sequencing circuitry in the IC that delays the start of the user design execution until a set of initial condition has been computed and propagated is provided. The sequencing holds the first group of circuits at an initial state while a second group of circuits computes and propagates a set of initial conditions based at least partly on the initial state of the first group of circuits. The circuits in the first group when being held disregard their inputs and do not change their outputs. The first group of circuits is released from its initial state after the second group of circuits has completed computation and propagation of the set of initial conditions. The circuits in the first group when released are freed to store or clock-in new inputs and produce new outputs in order to perform the user defined operations in conjunction with the second group of circuits. |

Pulse-width modulation data decoder
Systems and methods for decoding pulse-width modulated (PWM) data are disclosed. An example decoder filters a data input signal with a one-sided pulse filter. The one-sided pulse filter suppresses short pulses on the data input signal and passes long pulses. The example decoder latch the filtered data signal at the end of each bit time of the data input signal. The duration of pulses that are suppressed by the one-sided pulse filter can be calibrated to compensate for circuit variations and to allow the decoder to operate at various data rates. The decoder can be implemented in a small integrated circuit area and can be power efficient. |
