We provide in this thesis our contribution in the area of reconfigurable system synthesis. The RA unit is the hardware unit capable of flexibly configuring to the recommended configurations and hence run the workloads. multiplication in the odd dataflow and before beta multiplication in the even dataflow store integers from -127 to 128. CSD-860063. This dataflow computing method is used in automation applications [12], digital signal processing [13,14], mathematics for solving systems of equations [15], floating-point matrix multiplication [16], financial derivatives pricing [17], artificial neural networks [18], and much more. In HOTCHIPS 2017. 2. PT. [Wave DPU] [6] M. Thottethodi and T. N. Vijaykumar. A versatile vector-processing unit … Reconfigurable and approximate computing for video coding. SPU supports alias-free indirection with a compute-enabled scratchpad and aggressive stream reordering and stream-join with a novel dataflow control model for a reconfig-urable systolic compute-fabric. reconfigurable array in the processor core, limited to combinational logic only. The dataflow paradigm for parallel computing has a long history from the early 1970s. SambaNova Reconfigurable Dataflow Unit (RDU), the industry’s next-generation processor built from the ground up to offer native dataflow processing. Reconfigurable Content Addressable Memory Qutaiba Ali Computer Engineering Department, University of Mosul, Iraq Abstract: The content addressable memory is a memory unit that uses content matching instead of addresses. pp.1-8, 10.1109/ReCoSoC.2011.5981505.

Reconfigurable MAC Unit 2. CSD-860094. While the necessary functional units are different, the architecture is particularly well suited for linear, iterative dataflow. Figure1(a) depicts the programmer view of stream-dataflow, con-sisting of the dataflow graph itself, and explicit stream communica-tion for memory access, read reuse and recurrence. Tensor Processing Unit), coarse-grained reconfigurable arrays (CGRAs), and spatial architectures are repeatedly being demonstrated as a promising accelerator for these power and performance-critical loops [2–10]. This study presents a resource-efficient reconfigurable inference processor for recurrent neural networks (RNN), named AERO. We need to add the unbiased exponents: = 1+ 2. In this context, the dataflow programming model offers a very effective way to reduce the gap between high-level formulations and low-level implementations. This simplifies the control logic and diminishes the communication overhead between the reconfigurable array and the rest of the system. It also contains tiling, memory hierarchy, and data movement information. In: ASPLOS ’18, Proceedings of the twenty-third international conference on architectural support for programming languages and operating systems. This paper presents some interesting concepts of static dataflow machines that can be used by reconfigurable computing architectures. Eyeriss: An energy-efficient reconfigurable accelerator for deep cnns. A Bidirectional Speculation Unit (BSU) that predicts RTDS and skips zero-output computation in both FF and BP passes of training. Besides, data forwarding for the same input or weight data in one cycle for OS dataflow reduces the required memory bandwidth. A FINE-GRAINED DATAFLOW LIBRARY FOR RECONFIGURABLE STREAMING ACCELERATORS A Thesis in Electrical Engineering by Aarti Chandrashekhar ⃝c 2011 Aarti Chandrashekhar Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science December 2011 PRADA is composed by a control unit and several processing elements (PEs). 2.2 Coarse-grained reconfigurable systems: automatic multi-dataflow network composition The MDC tool was conceived for the automatic creation and management of ‘multi-dataflow’ systems. Analysing Reconfigurable Computing Systems (W Luk) Custom Computing or Vector Processing? A runtime reconfigurable 2D dataflow computing engine that can implement a variety of CNN operations in a systolic manner was proposed in Reference . The GAP comprises a processor front-end similar to that of a superscalar processor extended by a configuration unit and a two-dimensional array of functional units that forms the execution unit. While the necessary functional units are different, the architecture is particularly well suited for linear, iterative dataflow. dataflow specifications of the input applications a single multi-dataflow specification is assembled along with a configuration table. The satisfiability solver operates on subsets of interconnected nodes within a dataflow graph to derive a solution. [2] Yu-Hsin Chen et al. Tiziana Fanni received her degree in Electronic Engineering in 2014 and her PhD in 2019 at the University of Cagliari. RECONFIGURABLE ALGORITHMIC NETWORKS FOR AIRCRAFT DATA MANAGEMENT: Applicant name: Honeywell International Inc. ... or more precisely of a dataflow-oriented graphical program, see figure 3, [21] and [22] for the sole example of a RAN in the patent. Self-loop Pipelining and Reconfigurable Dataflow Arrays. BACKGROUND 2.1 Dataflow modeling In the dataflow model of computation, an application is repre- We report on a reconfigurable optical interconnection approach in which static communication graphs are extracted from high level programs and are mapped onto a two stage optical beam-steered/perfect shuffle interconnect. 3 Functional Unit Design We chose to build a platform similar to the RaPiD reconfigurable architecture [1]. The idea in some ways is that you could draw the path on a cocktail napkin, and the collection of Functional Units in the VTL can then be configured accordingly. As it becomes more difficult to increase single-threaded performance, focus on multi-core processor designs increases. It allows us to learn about how dataflow accelerators work, how we can validate our execution method (mappings) onto the accelerator with cycle-level details, a reconfigurable accelerator template (instead of building such a design from scratch), and easy prototyping and … Farabet et. •“Dataflow” Computing •Reconfigurable Computing •Time to Space Mapping ... MIT Tagged Token Dataflow Architecture* Wait-Match Unit &Token Waiting Token Store Instruction Fetch Unit Queue Program Store & even impossible Constant Store Form Token Unit Structure Flow“ A dataflow graph is configured using coarse grainted functional units to represent computational kernels. §Dept.
