Data transform acceleration using input/output virtualization

A host comprising:

• data processing hardware;
• one or more than one virtual machine on a host operating system of the host computing unit, with each virtual machine using one or more than one virtual function in the data transform accelerator;
• one or more software drivers in the host operating system in the host computing unit;
• one or more software drivers in a guest operating system in the virtual machines in the host computing unit;
• and
• memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• generate container data structures in a memory of the data transform accelerator, the data transform accelerator in data communication with the host or in the memory of the host computing unit, using the software driver in the host operating system of the host computing unit;
• generate input data in the memory hardware of host computing unit or in the memory of data transform accelerator by software driver in guest operating system of the virtual machine in the host computing unit;
• generate metadata in the memory of data transform accelerator or in the memory of host computing unit, or in in the memory of the data transform accelerator and in the memory of the host computing unit by software driver in a guest operating system of the virtual machine in the host computing unit;
• generate pre-data in the memory of data transform accelerator or in the memory of host computing unit, or in both in the memory of the data transform accelerator and in the memory of the host computing unit by software driver in guest operating system of the virtual machine in the host computing unit;
• generate additional metadata in the memory of data transform accelerator or in the memory of host computing unit, or in both in the memory of the data transform accelerator and in the memory of the host computing unit by software driver in guest operating system of the virtual machine in the host computing unit;
• reserve an output buffer in the memory hardware or in the memory of data transform accelerator or on the memory of host computing unit;
• generate a first data transform command in the memory hardware, the first data transform command associated with the input data and the metadata;
• and
• update the container data structure with an address of the first data transform command,
• wherein the address of the first data transform command is accessible by the data transform accelerator,
• wherein accessing the address of the first data transform command by the data transform accelerator causes the data transform accelerator to obtain the input data, to perform one or more data transform operations on the input data based on the metadata, pre-data and additional pre-data and to transmit output data to the output buffer, and
• wherein the output data is the input data after being transformed by the one or more data transform operations.
