Brandon Lucia: 我是高效能计算公司的首席执行官兼联合创始人,也是卡内基梅隆大学的教授。过去十年,我致力于能效计算和资源受限计算的研究。我们公司研发的技术源于在卡内基梅隆大学进行的十余年研究,其核心是彻底重新设计芯片架构,以实现最高的能效。传统上,人们通过增加算力来提高计算效率,而我们则从架构层面入手,在每个设计决策中都优先考虑能效。这与当前科技行业面临的挑战——如何在日益增长的计算需求下降低能耗——高度契合。 我们发现,许多AI应用中,除了机器学习部分,还有大量的数据预处理、规范化、数据格式转换等任务。专用AI处理器擅长处理机器学习部分,但对于其他任务则效率较低。而我们的芯片架构能够高效处理整个AI应用流程,包括数据采集、清洗、规范化、数字信号处理以及机器学习等,从而实现更高的端到端效率。 我们的芯片架构采用数据流模型,将程序分解成数据流图,并将其映射到芯片上的网格状结构中。这种并行处理方式能够显著提高性能,同时避免了传统冯·诺依曼架构中频繁的指令读取和解码操作,从而实现极高的能效。与市场上其他低功耗嵌入式CPU相比,我们的芯片在能耗方面最多可提升166倍,同时性能也具有竞争力。 我们的芯片已在基础设施传感、空间与国防应用以及健康与可穿戴设备领域得到应用。在空间应用中,尺寸、重量和功耗(SWAP)至关重要。我们的芯片能够显著降低卫星的功耗,从而减少电池和太阳能电池板的尺寸和重量,降低任务复杂性和风险。例如,在月球探测任务中,我们的芯片可以用于视觉导航,在能源受限的环境下实现高效的图像处理和机器学习。 未来,计算技术将从过度专业化转向注重能效的通用型计算。随着AI应用的普及,能源消耗将成为一个日益重要的因素。我们的芯片架构兼顾通用性和能效,能够满足各种计算任务的需求,并为未来的计算技术发展提供支持。
