Abstract: An apparatus and method for efficiently routing power signals across a semiconductor die. In various implementations, a computing system includes transmitters sending data signals to receivers that support using a prefix to provide clock recovery and alignment of the input bit stream that arrives at the receivers. Based on when a decoder of a receiver receives the prefixes, the decoder determines which clock cycles to skip writing data into a buffer of data processing circuitry. Therefore, the decoder prevents overflow of this buffer when the rate of insertion is greater than the rate of removal for this buffer. In contrast, the transmitter continues to send data during each clock cycle, and accordingly, avoids reducing the effective bandwidth on transmission lines in the presence of clock domain differences between transmitter and receiver.

When the counted number of arrived packets is “0”, the second unit determines that backward mismatch has occurred in the observation cycle.

Abstract: A content provider might be responsible for content transmitted over a large number of channels, including premium channels that may have fixed quality settings. In order to provide the appropriate quality, the encoders for the premium channels are able to obtain the bit rates (and other capacity) needed. The total bit rate used for the premium channels can then be compared against a maximum bit rate for all channels for the provider to determine a remaining bit rate. The remaining bit rate can then be allocated, evenly or otherwise, across the various non-premium channels. Transmission components such as statmuxes used for the non-premium channels can be configured to adjust the bit rates as necessary based at least in part upon the allocation. Such an approach enables the premium channels to provide the fixed quality ensuring that the aggregate bandwidth meets the bit rate limit.

When combined with techniques such as pipelining and horizontal scaling, the loading, hashing, and other processing occur in real time at the full speed of the underlying data path. For example, hashing throughput may sustainably equal or exceed the throughput of main memory.

Quantized time series data is generated from the time series data and the quantiles.

Alternatively, the user may choose to maximize the compression rate while placing an upper limit on the loss of information due to quantization. The compressed time series data that satisfies the user selected optimization conditions may be used to replace the original time series data in the data-storage device.
