the structure of the rocket-borne model is inherently complex, with processed images exhibiting high resolution and generating substantial amounts of data and calculations. Achieving robust real-timecomputing on an embedded platform poses significant challenges due to strictly limited resources, power consumption constraints, and size limitations. Our review of rocket-borne applications reveals considerable variability in the design resources of different devices, indicating a need for expanded design approaches. Upon evaluating existing methods, we identified two primary drawbacks. First, certain operators within the high-resolution target detection model are difficult to parallelize, resulting in significant inference delays that hinder the ability to meet task requirements. Although existing methods have been extended, there remains significant potential for performance enhancement in core scheduling for poor acceleration. this paper proposes an optimized architecture for the target detection algorithm accelerator designed for high-resolution images, along with a novel highly parallel data pre-processing and post-processing module implemented on FPGA to address these issues. Compared to the ARM implementation, this architecture demonstrates an improved performance of 24.64x. Furthermore, to ensure flexible application across various rocket launch scenarios, we introduce an optimization structure for convolution, pooling, and fusion operators and a multi-core expansion optimization method. this approach yields a 1.29x improvement in computing unit utilization compared to state-of-the-art multi-core scaling efforts. Finally, we assessed the accelerator architecture across multiple FPGA platforms, achieving a peak processing element utilization rate of 99.71% for a single core and layer. the overall computing efficiency, excluding the first layer, exceeded 90%. the peak computing power for the four cores reached 1638.4 GOPS, and the end-to-end computation time for

In recent years, flexible haptic sensors have gained significant attention for their potential in robotics, inspired by the tactile sensing capabilities of human skin. these sensors enable robots to detect a wide range of haptic information, such as pressure and slip, thereby enhancing their flexibility and sensory capabilities. this paper introduces a flexible 3D haptic sensor with high sensitivity and low hysteresis, designed to detect both normal and tangential forces. the sensor features a three-layer structure: the top layer consists of a flexible square magnet that deforms under external forces, enabling force detection; the middle layer is made of Ecoflex 00–30 elastomer; and the bottom layer is a flexible circuit board (FPCB) embedded with Hall sensors that convert magnetic field changes into electrical signals. the flexible sensor is integrated into a smart glove by sewing it onto the thumb and index finger positions. By combining sensor data with machine learning algorithms, the glove achieves handwriting recognition with a classification accuracy of 96.67%. Additionally, the glove incorporates slip sensing capabilities to monitor grip states in real-time during object manipulation. these features make the sensor highly suitable for applications in wearable technology and human-computer interaction, with promising prospects for advancing human-robot interaction and robotics in general.

Garbage collection considerably increases programmer productivity and software quality. However it is difficult to implement garbage collection both efficiently and suitably for real-timesystems. Today, garbage collection is exclusively realized in software and either fails to guarantee a small upper bound for pause times or suffers from considerable synchronization overhead In this paper we present the design and implementation of an on-chip garbage collection coprocessor that closely cooperates withthe main processor the benefits of this configuration include low garbage collection overhead, low-cost synchronization of collector and application programs, and hard real-time capabilities. We successfully realized the garbage collection coprocessor along with a pipelined RISC processor on a single FPGA. Performance measurements on the prototype show that the longest pauses caused by the garbage collector are less than 500 clock cycles and that the total runtime overhead is as little as a few percent if the application is provided with a reasonable amount of memory headroom.

Microkernel based systems tend to depend heavily on IPC. this paper adresses the problem of a system response spanning more than one task in an embeddedreal-time system. the approach is based on a mix of classical response time analysis equations and a graph based approach to estimate the impact of different parts of the system on the time needed by the system to respond. this approach has the major advantage of being intuitive.

In some real-time application systems, there are only a few distinct kinds of tasks, each of which may be instantiated several times during runtime. the scheduling of such sporadic task systems is considered here upon both a single processor, and on multiprocessor platforms under the partitioned paradigm of multiprocessor scheduling. Algorithms that have run-time polynomial in the number of tasks in the system are presented and proved correct.
