The living mycelium networks are capable of efficient sensorial fusion over very large areas and distributed decision making. The information processing in the mycelium networks is implemented via propagation of electrical and chemical signals en pair with morphological changes in the mycelium structure. These information processing mechanisms are...

Fungal electronics is a family of living electronic devices made of mycelium bound composites or pure mycelium. Fungal electronic devices are capable of changing their impedance and generating spikes of electrical potential in response to external control parameters. Fungal electronics can be embedded into fungal materials and wearables or used as...

Memristors close the loop for I-V characteristics of the traditional, passive, semi-conductor devices. A memristor is a physical realisation of the material implication and thus is a universal logical element. Memristors are getting particular interest in the field of bioelectronics. Electrical properties of living substrates are not binary and the...

Mycelium networks are promising substrates for designing unconventional computing devices providing rich topologies and geometries where signals propagate and interact. Fulfilling our long-term objectives of prototyping electrical analog computers from living mycelium networks, including networks hybridised with nanoparticles, we explore the possib...

Article
A fungal colony maintains its integrity via flow of cytoplasm along mycelium network. This flow, together with possible coordination of mycelium tips propagation, is controlled by calcium waves and associated waves of electrical potential changes. We propose that these excitation waves can be employed to implement a computation in the mycelium netw...

The use and location of memory in integrated circuits plays a key factor in their performance. Memory requires large physical area, access times limit overall system performance and connectivity can result in large fan-out. Modern FPGA systems and ASICs contain an area of memory used to set the operation of the device from a series of commands set...

The emerging field of living technologies aims to create new functional hybrid materials in which living systems interface with artificial ones. Combining research into living technologies with emerging developments in computing architecture has enabled the generation of organic electronics from plants and slime mould. Here, we expand on this work...

The rapidly developing research field of organic analogue sensors aims to replace traditional semiconductors with naturally occurring materials. Photosensors, or photodetectors, change their electrical properties in response to the light levels they are exposed to. Organic photosensors can be functionalised to respond to specific wavelengths, from...

FPGA-SoC technology provides a heterogeneous platform for advanced, high-performance systems. The System on Chip (SoC) architecture combines traditional single and multiple core processor topologies with flexible FPGA fabric. Dynamic reconfiguration allows the hardware accelerators to be changed at run-time. This paper presents a novel OpenGL compl...

Full-text available
The paper presents a synthesis tool that takes OpenGL shader language and produces the equivalent hardware for use on an FPGA. The hardware produced is optimised to remove duplication and uses critical path analysis for task scheduling and synchronisation. It is demonstrated that a performance optimised vertex shader implemented on an FPGA provides...

Memristors close the loop for I-V characteristics of the traditional, passive, semiconductor devices. Originally proposed in 1971,the hunt for the memristor has been going ever since. The key feature of a memristor is that its current resitance is a function of its previous resistance. As such, the behaviour of the device is influenced by changing...

Hardware acceleration is a common method for increasing processor performance. The processor offloads repetitive or computationally intense processes to dedicated hardware that can complete the task in a fraction of the time. Pairing accelerators with processors can be difficult if the processor is designed for general purpose use where it is not e...
Article
Full-text available
In high performance computing systems and signal processing, there is a basic set of mathematical functions that are essential. While addition, subtraction and multiplication are well understood, there is less literature on square-rooting, which is a particularly time- and resource-consuming function. Traditional non-restoring algorithms produce a...
Thesis
Full-text available
Demands on modern computing are becoming more intensive. Keeping up with these demands has increasing complexity. Moore's Law is in decline. Increasing the number of cores on a device has diminishing returns. Specialised architectures provide more efficient and higher performing processors. However, it is not always practical to include every archi...

Full-text available
Harvesting energy using the pyroelectric effect has seen growth as a potential energy source for low power applications, such as self-powered and autonomous wireless sensor networks. The scavenged energy is generally at low power levels, from mW to less than µW. While the voltages generated by pyroelectrics can be appreciable, the electric currents...
Conference Paper

Abstract: This study explores the benefits of the Dynamic Partial Reconfiguration (DPR) on Field Programmable Gate Array (FPGA) based System on Chip (SoC) architectures. Consideration is given to the constraints imposed by the implementation of partial reconfiguration on both pre-emptible context switching and continuous end-to-end dataflow applica...
