Abstract: 一种分配PCIE设备标识的方法,计算设备获取待分配的PCIE设备的标识与计算设备上端口的标识之间的对应关系,并且,该对应关系持久于计算设备中,然后,计算设备确定第一PCIE设备与计算设备连接的第一端口,并根据该第一端口的标识与获取的对应关系,为该第一PCIE设备分配标识。由于计算设备是根据持久化存储的端口标识与待分配的PCIE设备的标识之间的对应关系,为PCIE设备分配标识,因此,计算设备每次为各个PCIE设备分配的标识相同,从而实现为PCIE设备分配的标识固定,以此可以避免计算设备为各个PCIE设备分配的标识发生变化而影响计算设备上运行的业务对于PICE设备的访问。

Abstract: A method and apparatus for systems and methods for digital signal processing (DSP) in a non-volatile memory (NVM) device comprising CMOS coupled to NVM die, of a data storage device. According to certain embodiments, one or more DSP calculations are provided by a controller to the CMOS components of the NVM, that configure one or more memory die to carry out atomic calculations on the data resident on the die. The results of calculations of each die are provided to an output latch for each die, back-propagating data back to the configured calculation portion as needed, otherwise forwarding the results to the controller. The controller aggregates the results of DSP calculations of each die and presents the results to the host system.

Abstract: 提供了一种存储器芯片、电路组件、电子设备和用于控制存储器芯片的方法。存储器芯片(220-11 )包括复位引脚(204)、多个命令地址引脚(202)、存储器单元(240)和模式设置电路(230)。在复位引脚(204)接收到低电平时,进入复位模式。模式设置电路(230)根据在复位模式下多个命令地址引脚(202)接收到的电平图案,生成用于将存储器芯片(220-11 )设置为标准模式或是镜像模式的模式设置信号,并且在复位结束时,使得存储器芯片(220-11 )按照设置的模式操作。通过在复位期间使用多个命令地址引脚(202)接收到的电平图案来设置操作模式并且在复位结束之后使得存储器芯片(220-11 )按照设置的模式操作,可以节省原本在正常操作模式期间设置和维持操作模式的镜像引脚。因此,可以减少存储器芯片(220-11 )的引脚数量以使得存储器更小型化,或是将其留作他用以增强存储器芯片(220-11 )的性能。

Abstract: Systems and methods are disclosed for a configurable interconnect address remapper with event detection. For example, an integrated circuit can include a processor core configured to execute instructions. The processor core includes region registers defined by a From Address range and a To Address, a register storing a number of regions defined in the integrated circuit, interrupt enable registers associated with each pair of region registers, and event flags associated with each pair of region registers; an interconnection system handling transactions from the processor core; an interconnect address remapper translating an address associated with a transaction using the one or more pair of region registers; and an interrupt controller receiving an interrupt signal from the interconnect address remapper when the interrupt enable registers are enabled and at least one raised event flags when at least one of the one or more pair of region registers matches the transaction address.
