Combined Control Flow Dominated and Data Flow
نویسندگان
چکیده
This paper presents the design of a Videophone Coder-Decoder Motion Estimator using two High-Level Synthesis tools. Indeed, the combination of a Control Flow Dominated part (complex communication protocol) with a Data Flow Dominated part (high throughput computations) makes this circuit diicult to be synthesized by a single HLS tool. The combination of two HLS tools for the high-level design of this operator required the deenition of a sophisticated design ow allowing mixed-level and multi-language simulations. When compared to design starting from RTL specii-cations, HLS induces only a negligible area overhead of 5%, and provides gain in description length (divided by 5), design time and exibility.

Numerical Study of the Mass Transfer Effects on the Flow and Thermal Fields Structures under the Influence of Natural Convection
In this paper, a numerical study has been carried out for coupled mass, momentum and heat transfer in the field under effects of natural convection. For this purpose, the unsteady incompressible Navier-Stokes equations with the terms of the Buoyancy forces (due to temperature gradients), energy conservation and concentration (mass) transfer equations have been simultaneously solved using approp...
متن کاملInvestigation on Turbulent Nanofluid Flow in Helical Tube in Tube Heat Exchangers
In this study, the thermal characteristics of turbulent nanofluid flow in a helical tube in the tube heat exchanger (HTTHE) were assessed numerically through computational fluid dynamics (CFD) simulation. The findings of both the turbulent models: realizable k-epsion (k-ε) and re-normalisation group (RNG) k-epsilon were compared. The temperature distribution contours show that realizable and RN...
متن کاملCombined effect of hall current and chemical reaction on MHD flow through porous medium with heat generation past an impulsively started vertical plate with constant wall temperature and mass diffusion
Unsteady flow with magneto-hydrodynamics and heat generation through porous medium past an impulsively started vertical plate with constant wall temperature and mass diffusion is considered here. The effect studied is a combination of Hall current and chemical reaction. The motivation behind this study is the applications of such kind of problems in industry. In many industrial applications ele...
متن کاملبررسی سرریزهای زیگزاگی با پلان قوسی
A labyrinth spillway is an overflow spillway to regulate and control flow in canals, rivers and reservoirs. The main hypothesis for the development of such a spillway is to increase the discharge per unit width of structure for a given headwater. This type of structure is often an efficient alternative to a gated-spillway type where either the increase of the flood-passage capacity or the con...
