Tydi-lang: a language for typed streaming hardware: A manual for future Tydi-lang compiler developers
No full textTransferring composite data structures with variable-length fields often requires designing non-trivial protocols that are not compatible between hardware designs. When each project designs its own data format and protocols the ability to collaborate between hardware developers is diminished, which is an issue especially in the open-source community. Because the high-level meaning of a protocol is often lost in translation to low-level languages when a custom protocol needs to be designed, extra documentation is required, the interpretation of which introduces new opportunities for errors. The Tydi specification (Tydi-spec) was proposed to address the above issues by codifying the composite and variable-length data structures in a type and providing a standard protocol to transfer typed data among hardware components. The Tydi intermediate representation (Tydi-IR) extends the Tydi-spec by defining typed interfaces, typed components, and connections among typed components.In this paper, we propose Tydi-lang, a high-level hardware description language (HDL) for streaming designs. The language incorporates Tydi-spec to describe typed streams and provides templates to describe abstract reusable components. We also implement an open-source compiler from Tydi-lang to Tydi-IR. We leverage a Tydi-IR to VHDL compiler, and also present a simulator blueprint to identify streaming bottlenecks. We show several Tydi-lang examples to translate high-level SQL to VHDL to demonstrate that Tydi-lang can efficiently raise the level of abstraction and reduce design effort.https://github.com/twoentartian/tydi-lang Source code for the thesis project.Computer Scienc

Warming effects on consumption and intraspecific interference competition depend on predator metabolism
No full text1. Model analyses show that the stability of population dynamics and food web persistence increase with the strength of interference competition. Despite this critical importance for community stability, little is known about how external factors such as the environmental temperature affect intraspecific interference competition. 2. We aimed to fill this void by studying the functional responses of two ground beetle species of different body size, Pterostichus melanarius and Poecilus versicolor. These functional response experiments were replicated across four predator densities and two temperatures to address the impact of temperature on intraspecific interference competition. 3. We generally expected that warming should increase the speed of movement, encounter rates and in consequence interference among predator individuals. In our experiment, this expectation was supported by the results obtained for the larger predator, P. melanarius, whereas the opposite pattern characterized the interference behaviour of the smaller predator P. versicolor. 4. These results suggest potentially nontrivial implications for the effects of environmental temperature on intraspecific interference competition, for which we propose an explanation based on the different sensitivity to warming of metabolic rates of both species. As expected, increasing temperature led to stronger interference competition of the larger species, P. melanarius, which exhibited a weaker increase in metabolic rate with increasing temperature. The stronger increase in the metabolic rate of the smaller predator, P. versicolor, had to be compensated by increasing searching activity for prey, which did not leave time for increasing interference. 5. Together, these results suggest that any generalization how interference competition responds to warming should also take the species' metabolic response to temperature increases into account.German Research Foundation [BR 2315/6-1, BR2315/8-1, BR2315/13
