P4 to SDNet: Automatic Generation of an Efficient Protocol-Independent Packet Parser on Reconfigurable Hardware

Many digital systems provide multiple but closely related functionalities, not all of them are required simultaneously. Dedicated hardware solution for each functionality will waste too much silicon area. This work presents automatic generation of a shared hardware solution for a set of functionalities which will execute only one functionality at a time. This shared hardware solution is termed as “Multi-Circuit”. A Multi-Circuit can be embedded as a configurable component in a System-on-Chip (SoC) design. Multi-Circuit is generated by initially mapping a given set of application functionalities on a common reconfigurable platform. Later on, all the unused logic and routing resources are efficiently removed from the reconfigurable hardware. Experiments reveal that Multi-Circuit is 18–42% smaller than the previously proposed technique named Application Specific Inflexible FPGA (ASIF). Multi-Circuit is 73–84% smaller than its corresponding FPGA design.

Abstract. The Simon effect lies on the automatic generation of a stimulus spatial code, which, however, is not relevant for performing the task. Results typically show faster performance when stimulus and response locations correspond, rather than when they do not. Considering reaction time distributions, two types of Simon effect have been individuated, which are thought to depend on different mechanisms: visuomotor activation versus cognitive translation of spatial codes. The present study aimed to investigate whether the presence of a distractor, which affects the allocation of attentional resources and, thus, the time needed to generate the spatial code, changes the nature of the Simon effect. In four experiments, we manipulated the presence and the characteristics of the distractor. Findings extend previous evidence regarding the distinction between visuomotor activation and cognitive translation of spatial stimulus codes in a Simon task. They are discussed with reference to the attentional model of the Simon effect.
