Systems, apparatuses, and methods for performing shader writes to compressed surfaces are disclosed. In one embodiment, a processor includes at least a memory and one or more shader units. In one embodiment, a shader unit of the processor is configured to receive a write request targeted to a compressed surface. The shader unit is configured to identify a first block of the compressed surface targeted by the write request. Responsive to determining the data of the write request targets less than the entirety of the first block, the first shader unit reads the first block from the cache and decompress the first block. Next, the first shader unit merges the data of the write request with the decompressed first block. Then, the shader unit compresses the merged data and writes the merged data to the cache.

A method and system is provided for allowing signals across electrical domains. The method includes applying a clock signal (of at least 1 GHz) to an electronic element in a location having first electrical properties. Data is output from the first electronic element; and received at a second electronic element located in a location having second electrical properties. The first and second electrical properties are different by either voltage and clock frequency.
