An apparatus and method are described for reducing power when reading and writing graphics data. For example, one embodiment of an apparatus comprises: a graphics processor unit (GPU) to process graphics data including floating point data; a set of registers, at least one of the registers of the set partitioned to store the floating point data; and encode/decode logic to reduce a number of binary 1 values being read from the at least one register by causing a specified set of bit positions within the floating point data to be read out as 0s rather than 1s. 描述了当读取和写入图形数据时用于减少功率的装置和方法。例如，装置的个实施例包括：图形处理单元(GPU)，其用于处理包括浮点数据的图形数据；组寄存器，该组中的寄存器中的至少个寄存器被划分用于存储浮点数据；以及编码/解码逻辑，其用于通过使浮点数据内的指定组的比特位置被读出为0而非1来减少从该至少个寄存器读取的二进制1值的数量。
