PAYLOAD CACHING

In one embodiment, a computer system includes a payload subsystem including an interface to connect with, communicate data with, and receive write transactions from respective devices, a classifier to classify the received write transactions into payload data and control data, a payload cache to store the classified payload data; a processing unit (PU) subsystem, the processing unit (PU) subsystem comprising: a local PU cache to store the classified control data, where the payload cache and the local PU cache are different physical caches in respective different physical locations in the computer system; and processing core circuitry configured to execute software program instructions to perform control and packet processing in response to the control data stored in the local PU cache. 在一个实施方式中，一种计算机系统包括：净荷子系统，该净荷子系统包括：用于与相应设备连接、与相应设备传送数据并且从相应设备接收写入事务的接口，用于将接收到的写入事务分类为净荷数据和控制数据的分类器，用于存储已分类的净荷数据的净荷高速缓存；处理单元（PU）子系统，该处理单元（PU）子系统包括：用于存储已分类的控制数据的本地PU高速缓存，其中净荷高速缓存和本地PU高速缓存是计算机系统中的相应不同物理位置中的不同物理高速缓存；和处理核心电路，该处理核心电路被
