Reversible logic is becoming increasingly important withthe rise of technologies like quantum computing, as it retains information during computation and maintains a one-to-one mapping between input and output patterns. Quantum circuits are inherently reversible and the best computational model in quantum computing systems. Some quantum signal processing applications like filters and image processing applications require the results of arithmetic operations to be saturated. Saturation occurs when adding two numbers withthe same sign and this can be done through a quantum saturating adder. this paper proposed a reversible quantum saturating adder with efficient quantum criteria like quantum cost, number of ancilla, and number of garbage outputs. We firstly propose a reversible n-bit quantum saturation generator block which is applied to a quantum adder and construct a quantum saturating adder circuit. the proposed circuit is simulated using the Quirk online tool and the result confirms the accuracy of the design. this design achieves 18% and 33% improvement in quantum cost and garbage outputs, compared to its counterpart, respectively.

Chromatic dispersion is one of the error sources limiting the transmission capacity in coherent optical communication that can be mitigated with digital signal processing. In this paper, the current status and plans of implementation of chromatic dispersion compensation (CDC) filters on FPGAs are discussed. As these high-speed filters are most efficiently implemented in the frequency-domain, different approaches for high-speed FFT-based architectures are considered and preliminary results of fully parallel FFT implementation by utilizing FPGA hardware features are presented.

In this paper we investigate implementing a Precision Time Base (PTB) technique to improve measurement jitter performance of digital sampling oscilloscopes (DSO) on a fieldprogrammable Gate Array (FPGA). To achieve better measurements, two reference signals are used to correct time-base errors and minimize jitter added by the DSO itself (minimize measurement jitter). We show experimentally that using the aforementioned technique, measurement jitter can be reduced from 1.3 pico-seconds (ps) to 280 femto-seconds (fs) (depending on the data rate and the pattern length) on a high-speed DSO.

FPGA hardware accelerators have recently enjoyed significant attention as platforms for further accelerating computation in the datacenter but they potentially add additional layers of hardware and software interfacing that can further increase communication latency. In this paper, we characterize these overheads for streaming applications where latency can be an important consideration. We examine the latency and throughput characteristics of traditional server-based PCIe connected accelerators, and the more recent approach of network attached FPGA accelerators. We additionally quantify the additional overhead introduced by virtualising accelerators on FPGAs.

In this paper, FPGA based enhanced decimator utilizing DA is introduced for remote applications for giving better answers for inspecting rate modifications. the proposed decimator is planned utilizing Poly stage disintegration strategy. Circulated Arithmetic (DA) Algorithm which is a multiplier free methodology is utilized for devouring less equipment assets and to bring about a rapid decimator. Equipment multifaceted nature is decreased by utilizing advanced Look up Table (LUT) apportioning. the proposed configuration shows an improvement of 6.2-14% in speed. By devouring practically same number of cuts and F/Flops, number of LUTs is diminished by 11.95-17.63% demonstrating prudent arrangement. At long last the created decimator configuration is mimicked and incorporated on Virtex 2 Pro based objective fieldprogrammable Gate Array (FPGA).

Soft processors are an important tool in the fieldprogrammable Gate Array (FPGA) designer's toolkit, and their Single Instruction Multiple Data (SIMD) organizations are an efficient means to utilize the parallelism of FPGAs. However, the state-of-the-art SIMD processors are hindered by the additional logic complexity resulting from dynamic features. By minimizing such constructs, it is possible to design soft processors that are efficient but still flexible enough to operate within an application domain. To this end, we propose a family of instruction set programmable multi-issue wide SIMD soft cores. the template is based on a highly static Transport Triggered Architecture (TTA) and a design time customizable shuffle unit to minimize inefficient dynamic features while remaining compiler programmable. the cores are evaluated on the PYNQ-Z1 board against the ARM A9 hard processor system with NEON vector extensions. the proposed cores reach up to 2.4x performance improvement over the ARM, can fit up to 1024 bit wide SIMD units onto the relatively small FPGA, while still operating at above 100 MHz. the scalability of TTA enables state of the art vector widths. the multicore scalability of the template is preliminarily tested with a 14-core design on a XCZU9EG FPGA customized for real-time convolutional neural net inference.

Program logics typically reason about an over-approximation of program behaviour to prove the absence of bugs. Recently, program logics have been proposed that instead prove the presence of bugs by means of under-approximate reasoning, which has the promise of better scalability. In this paper, we present an under-approximate program logic for a nondeterministic graph programming language, and show how it can be used to reason deductively about program incorrectness, whether defined by the presence of forbidden graph structure or by finitely failing executions. We prove this 'incorrectness logic' to be sound and complete, and speculate on some possible future applications of it.
