ACCESSING DIFFERENT TYPES OF MEMORY BY RESPECTIVE COMMANDS WITH DIFFERENT TIMING REQUIREMENTS

摘要

A system is provided that includes a remote device and bus controller coupled to the remote device via a digital network bus. The remote device includes one or more data channels for respective one or more peripherals, and includes volatile channel-based memory for each data channel and non-volatile device-based memory for the remote device. The bus controller is and configured to send a command across the network bus to the remote device, and in response thereto, the remote device is configured to acquire data from a designated data channel or command the designated data channel to perform a conversion. The command is from a communication protocol with which the remote device is compatible, and includes a set of channel commands for accessing the channel-based memory, and a different, distinct set of device-memory commands for accessing the device-based memory. The channel commands and device-memory commands have different timing requirements.

1. A system comprising:
a remote device including one or more data channels for respective one or more peripherals, and including volatile channel-based memory for each data channel and non-volatile device-based memory for the remote device; and a bus controller coupled to the remote device via a digital network bus, and configured to send a command across the network bus to the remote device, and in response thereto, the remote device is configured to acquire data from a designated data channel or command the designated data channel to perform a conversion, wherein the command is from a communication protocol with which the remote device is compatible, the communication protocol including a set of channel commands for accessing the channel-based memory, and a different, distinct set of device-memory commands for accessing the device-based memory, the channel commands and device-memory commands having different timing requirements.
