Title:
STORAGE DEVICE FOR COMPRESSING THE SAME INPUT VALUE
Document Type and Number:
WIPO Patent Application WO/2004/051492
Kind Code:
A1
Abstract:
A storage device for compressing the same input value by using an input processing section, a data storage device, a FIFO memory, and an output processing section. The input processing section checks, for the input value, data stored in the address position in the data storage device and corresponding to the input value. When the data represents an ineffective value, the initial value is stored in an address position corresponding to the input value, and the input value is stored in a FIFO memory. When the data represents an effective value, the data is operated and written back to the address position corresponding to the input value. When the input value is stored in the FIFO memory and when the data stored in the address position in the data storage device and corresponding to the input value represents an effective value, the output processing section outputs the input value, reads the data stored in the address position and corresponding to the input value, and outputs it as output data.
