In the domain of safety critical real-timecomputing, the ever increasing demand for processing power and robust safety guarantees has fueled the development of solutions to support the development of multicore and multi-CPU distributed software architectures. These architectures offer the potential for achieving enhanced computational power by exploiting the high-level of hardware parallelism, but they also raise significant challenges in ensuring temporal guarantees, such as the absence of deadlocks and race conditions, compliance with time budgets, etc. In this paper we present our ongoing work of developing a workflow for developing multi-CPU software applications from high level requirements down to the integrated system. The workflow is supported by several models and is specified with the FTG+PM formalism. We illustrate the workflow using two industrial applications from the aeronautical domain.

In dialysis patients, monitoring vascular flow of the surgically created arteriovenous fistula (AVF) is critical to indicate the success of the AVF as a dialysis access site. Current gold standard to quantify vascular flow involves external doppler evaluation which requires frequent visits to the clinic. In this paper, we present a proof-of-concept cost-efficient vascular flow monitoring system towards a wearable and robust blood flow monitoring system. The proposed system captures beat-to-beat blood flow from impedance plethysmography (IPG) signal and performs embeddedcomputing to robustly map the changes in the IPG to peripheral blood flow. We present the proof-of-concept results for the embeddedreal-time blood flow computing from measurements obtained using a custom electrical bioimpedance hardware presented previously elsewhere. We anticipate the results serving as the first step towards potentially eliminating the need for using expensive and bulky systems that require specialized personnel to operate for peripheral blood flow monitoring.

The increasing demand for computational resources keeps outpacing available User Equipment (UE). To overcome intrinsic hardware limitations of UEs, computational offloading was proposed. The combination of UE and seemingly endless computational capacity in the cloud aims to cope with those limitations. Numerous frameworks leverage Edge computing (EC) but a significant drawback of this is the required infrastructure. Some use cases however, do not benefit from lower response time and can remain in the cloud, where more potent resources are at one's disposal. Main contributions are to determine computational demands, allocate serverless resources, partition code and integrate computational offloading into a modern software deployment process. By focusing on non-time-critical use cases, drawbacks of EC can be neglected to create a more developerfriendly approach. Originality lies in the resource allocation of serverless resources for such endeavours, appropriate deployment of partitions and integration into CI/CD pipelines. Methodology used will be Design Science Research. Thus, many iterations and proof-of-concept implementations yield knowledge and artefacts.

There is an evident need to complement embedded critical control logic with AI inference, but today's AI-capable hardware, software, and processes are primarily targeted towards the needs of cloud-centric actors. Telecom and defense airspace industries, which make heavy use of specialized hardware, face the challenge of manually hand-tuning AI workloads and hardware, presenting an unprecedented cost and complexity due to the diversity and sheer number of deployed instances. Furthermore, embedded AI functionality must not adversely affect real-time and safety requirements of the critical business logic. To address this, end-to-end AI pipelines for critical platforms are needed to automate the adaption of networks to fit into resource-constrained devices under critical and real-time constraints, while remaining interoperable with de-facto standard AI tools and frameworks used in the cloud. We present two industrial applications where such solutions are needed to bring AI to critical and resource-constrained hardware, and a generalized end-to-end AI pipeline that addresses these needs. Crucial steps to realize it are taken in the industry-academia collaborative FASTER-AI project.

Semantic segmentation of RGB-T images is a complex task due to the challenges involved in fusing information from multi-modalities, which requires significant computational resources. This paper presents a novel and lightweight network architecture for RGB-T semantic segmentation that incorporates a parameter-free feature fusion module to integrate complementary information from different modalities. Furthermore, we propose a pretrained parameter selection strategy to improve convergence speed and accuracy. The network is designed to be computationally efficient and lightweight, making it well-suited for real-timeapplications. Our network architecture employs middle fusion techniques to extract features with separate encoders from the different modalities, and then a parameter-free cross-modal attention mechanism is designed to selectively connect the most relevant information from each modality. Additionally, we investigate the impact of pretrained parameter selection on the performance of the network. Experimental results on an urban scene dataset demonstrate that our approach outperforms real-time state-of-the-art methods in the literature while showing comparable performance with state-of-the-art methods that require up to 100 times the computational complexity. Our findings highlight the potential of the RGB-T fusion-based semantic segmentation for applications in real-world scenarios.
