    • A controller uses N dedicated ports to receive N signals from N non-volatile memories independent of each other, and uses a bus in a time shared manner to transfer data to and from the N non-volatile memories. The controller receives from a processor, multiple operations to perform data transfers, and stores the operations along with a valid bit set active by the processor. When a signal from a non-volatile memory is active indicating its readiness and when a corresponding operation has a valid bit active, the controller starts performance of the operation. When the readiness signal becomes inactive, the controller internally suspends the operation and starts performing another operation on another non-volatile memory whose readiness signal is active and for which an operation is valid. A suspended operation may be resumed any time after the corresponding readiness signal becomes active and on operation completion the valid bit is set inactive.
    • 控制器使用N个专用端口从N个非易失性存储器中独立地接收N个信号,并且以时间共享的方式使用总线将数据传送到N个非易失性存储器和从N个非易失性存储器传送数据。 控制器从处理器接收多个操作来执行数据传输,并且存储操作以及由处理器激活的有效位。 当来自非易失性存储器的信号有效时表示其准备状态,并且当对应的操作具有有效位时,控制器开始执行该操作。 当准备信号变得不活动时,控制器内部暂停操作,并开始对准备信号有效并且操作有效的另一个非易失性存储器执行另一个操作。 在相应的就绪信号变为有效之后的任何时候,可以恢复暂停的操作,并且在操作完成时,有效位被设置为不活动。

    • A wireless local area network (WLAN) transceiving integrated circuit includes a WLAN interface, an input buffer, an input buffer controller, and a processor. The WLAN transceiving integrated circuit may also include an output buffer, an output buffer controller, a transcoder, and/or an audio Coder-Decoder (CODEC). The WLAN transceiving integrated circuit is installed in a WLAN device that services voice communications. The input buffer receives packetized audio data from the WLAN interface. When the input buffer satisfies a buffer vacancy threshold, the processor and the input buffer controller cooperatively operate to fill at least a portion of the input buffer with packetized audio data. The processor copies packetized audio data from the input buffer and fills the input buffer with the copied packetized audio data to maintain an audio pattern in the input buffer. The input buffer controller fills the input buffer when the processor is available and after copying/filling is no longer effective. The processor operates to maintain the audio pattern when additional packetized audio data is received by the WLAN interface. These operations are also performed for the output buffer, which receives packetized audio data from the transcoder and writes the packetized audio data to the WLAN interface.
