Low‐power pipelined phase accumulator with sequential clock …
To enhance the speed performance in conventional DDFSs, a highly pipelined phase accumulator (PACC) is adopted, which is followed by a phase-to-sine amplitude converter (PSC) and a D/A converter. As the pipeline depth increases for higher-speed operation, a PACC becomes the most power-consuming block in a DDFS . Many …

A 5.3-GHz 32-bit accumulator designed for direct digital
A 32-bit pipeline accumulator with carry ripple topology is implemented for direct digital frequency synthesizer. To increase the throughout while hold down the area and power consumption, a method to reduce the number of the pre-skewing registers is proposed. The number is reduced to 29% of a conventional pipeline accumulator. The …

Pipeline Voter Based on Moving Accumulator Sign Filter
Based on the moving average filter, a moving accumulative sign filter is proposed, its performance is analysed comprehensively, and it can be applied to the structure of pipeline voter, which can be used for the detection of a single digital signal, and can also be used for the majority voter of two signals.

Thermal Accumulators | Plumbing & Mechanical
Thermal accumulators service both space heating and domestic water heat loads. A common configuration uses an internal heat exchanger near the bottom of the tank to accept input from an array of solar collectors. Placing the coil there allows the collector circuit to operate at the lowest possible temperature and the highest possible efficiency.
Make a HLS function asynchronous with respect to the main one
So, my main function calls the adding one: bool adder (double A, double B, bool valid, double *res) {. #pragma HLS pipeline II=1. *res = A + B; return valid; // this is important. } The latency of the adder is, let''s say, 5 cycles. Due to data dependencies in the main function, Vivado HLS produces an architecture that accepts data once ever 5 ...

Expert-verified. It is required to transmit 36.76 kW power from an accumulator through a pipeline 100 mm di- ameter and 1500 m long. The ram is loaded with a weight of 1226.25 kN and the friction loss in the pipeline equals 2 per cent of the total power 2 being transmitted. Determine the diameter of the ram if friction co-efficient, f = 0.01.

Getting Started with Aggregation Pipelines in Python | MongoDB
Aggregation pipelines are executed by PyMongo using Collection''s aggregate () method. The first argument to aggregate() is a sequence of pipeline stages to be executed. Much like a query, each stage of an aggregation pipeline is a BSON document, and PyMongo will automatically convert a dict into a BSON document for you.
algorithm
A pipelined accumulator is fairly simple. For a 32-bit accumulator, break the 32-bits into chunks that fit in each pipeline stage -- I''ll use 8-bits in each pipeline stage for this example. You will then need 4 stages to compute it. Each stage of 8-bits has an overflow bit, which is used as the carry-in to the 8-bits in the next stage.
