Adapter device for large address spaces

An adapter device comprising:

• a sequential address buffer;
• a sequential data buffer;
• and
• a memory, wherein a region of the memory is configured as a data block, wherein the data block is associated with an address range, wherein the address range corresponds to a region of an address space of a target device;
• wherein the adapter device is operable to:
• receive a first write transaction, the first write transaction having a first address and first data;
• write the first address to the sequential address buffer;
• determine that the first address is within the address range;
• write the first data to the data block;
• upon occurrence of a first event, write the first data from the data block to the region of the address space of the target device;
• receive a second write transaction, the second write transaction having a second address and second data;
• write the second address to the sequential address buffer;
• determine that the second address is outside the address range;
• write the second data to the sequential data buffer;
• upon occurrence of a second event, read third data from a first entry in the sequential data buffer;
• read a third address from a second entry in the sequential address buffer, the second entry corresponding to the first entry;
• and
• write the third data to the target device using the third address.

An adapter device, comprising:

• a sequential address buffer;
• and
• a sequential data buffer;
• wherein the adapter device is operable to communicate with a host device and a target device, and wherein the adapter device is operable to:
• receive a write transaction from the host device, the write transaction having an address and data, wherein the write transaction is directed to the target device;
• write the address to the sequential address buffer;
• write the data to the sequential data buffer;
• and
• upon occurrence of an event:
• read first data from a first entry in the sequential data buffer;
• read a first address from second entry in the sequential address buffer, wherein the second entry corresponds to the first entry due to the first address being associated with the first data;
• write the first data to the target device using the first address;
• determine that the first address is within a region of an address space of the target device;
• determine that other addresses included in other entries in the sequential address buffer are within the region of the address space of the target device;
• extract additional data from entries in the sequential data buffer, wherein the additional data is associated with the other addresses;
• and
• write the additional data to the target device, wherein the first data is written with the additional data.

A method comprising:

• receiving, at an adapter device, a first write transaction from a host device, the first write transaction having first address and first data, wherein the adapter device includes a sequential address buffer and a memory, wherein a first region of the memory is configured as a sequential data buffer and a second region of the memory is configured as a data block, the data block having an address range, wherein the address range corresponds to a region of memory of a target device;
• writing, by the adapter device, the first address to the sequential address buffer;
• determining that the first address is within the address range;
• writing the first data to the data block;
• receiving a second transaction from the host device, the second transaction having a second address and second data;
• writing the second address to the sequential address buffer;
• determining that the second address is outside the address range;
• writing the second data to the sequential data buffer;
• upon occurrence of a first event, writing the first data to the region of memory of the target device;
• and
• upon occurrence of a second event, reading data from each entry of the sequential data buffer and writing the data read from each entry to the target device using an address from a corresponding entry in the sequential address buffer.
