Researchers have developed Kaleido, a novel algorithm-hardware co-design approach to accelerate video diffusion transformers (vDiTs). This method exploits spatiotemporal correlations within the latent space of vDiTs, which are computationally intensive due to their self-attention mechanisms. Kaleido introduces a channel-wise reuse algorithm that reduces redundant computations while maintaining high generative quality, achieving over 17 dB improvement. The associated hardware accelerator is designed with reconfigurable processing elements and a specialized data dispatcher to efficiently handle the algorithm's sparsity and data access patterns. Evaluations demonstrate that Kaleido can provide up to 5.9x speedup and 16.0x energy savings compared to existing state-of-the-art accelerators for vDiT models. AI
