Look-up table compression method and look-up table reading method for computation equipment and its host and device

Computation equipment comprising:

• a device;
• and
• a host which retrieves an original data from an original look-up table by using an original table address, wherein the host checks the original data according to a reconstruction condition to obtain a check result, the host converts the original data into a reconstructed data according to the check result, the host writes the reconstructed data to a compressed look-up table by using a compressed table address, the host writes a relationship among the original table address, the compressed table address, and the check result to a mapping table, and the host stores the compressed look-up table and the reconstruction condition to the device.

A host comprising:

• a memory;
• and
• a processor which retrieves an original data from an original look-up table of the memory by using an original table address, wherein the processor checks the original data according to a reconstruction condition to obtain a check result, the processor converts the original data into a reconstructed data according to the check result, the processor writes the reconstructed data to a compressed look-up table by using a compressed table address, the processor writes a relationship among the original table address, the compressed table address, and the check result to a mapping table, the processor stores the mapping table to the memory, and the processor provides the compressed look-up table and the reconstruction condition to a device.

Computation equipment comprising:

• a host which retrieves a compressed table address and a bitmap from a mapping table by using an original table address;
• and
• a device coupled to the host to receive the compressed table address and the bitmap, wherein the device retrieves a reconstructed data from a compressed look-up table by using the compressed table address, and the device converts the reconstructed data into an original data according to the bitmap and a reconstruction condition.

A device comprising:

• a memory;
• and
• a processor which receives a compressed table address and a bitmap from a host, wherein the processor retrieves a reconstructed data from a compressed look-up table of the memory by using the compressed table address, and the processor converts the reconstructed data into an original data according to the bitmap and a reconstruction condition.

A host comprising:

• a memory;
• and
• a processor which retrieves a compressed table address and a bitmap from a mapping table of the memory by using an original table address, wherein the processor provides the compressed table address and the bitmap to a device, so that the device retrieves a reconstructed data from a compressed look-up table by using the compressed table address, and the device converts the reconstructed data into an original data according to the bitmap and a reconstruction condition.
