<p>With the rapid development of information technology, artificial intelligence and large-scale models have exhibited exceptional performance and widespread applications. Photonic hardware offers a promising solution to meet the growing demands for computational power and energy efficiency. Researchers have aimed to develop an efficient integrated photonic computing chip capable of supporting a wide range of application scenarios in both static and dynamic temporal domains. However, with several mainstream photonic components already well-developed, achieving fundamental breakthroughs at the level of basic computing units remains highly challenging. Here, we report a novel algorithm-hardware co-design strategy that enables in situ reconfigurability across diverse neural network models, all within a unified photonic configuration. We unlock the intrinsic capabilities of a compact cross-waveguide coupled microring component to natively support both static and dynamic temporal tasks. As a proof of concept, we experimentally integrated a turnkey soliton microcomb as the light source on the photonic computing platform, demonstrating the realization of fully connected, convolutional, and recurrent neural network models within a unified structure. The chip achieves area computing efficiency of up to 2.45 TOPS/mm² for 208 tunable components. We evaluate the performance of the proposed chip by implementing image classification tasks on the MNIST and CIFAR-10 datasets, achieving measured test accuracies of 92.93% and 56.57%, respectively. Sentiment analysis on the IMDB dataset achieves a measured test accuracy of 80.81%. Furthermore, speech recognition is implemented by combining three neural networks within a scaled-up architecture. This work addresses the challenges of performing versatile computations on integrated photonic platforms, offering a promising solution for chip-integrated multifunctional photonic information processing. </p>
