In CPU design, a Sum Addressed Decoder or Sum Addressed Memory (SAM) Decoder is a method of reducing the latency of the CPU cache access. This is achieved by fusing the address generation sum operation with the decode operation in the cache SRAM.

... Many decoder designs avoid high-Fan-In AND gates in the decode line itself by employing a predecode stage ... For instance, an 11 bit decoder might be predecoded into three groups of 4, 4, and 3 bits each ... The decoder line then becomes a 3 input AND gate ...
Famous quotes containing the words sum and/or addressed:
“the possibility of rule as the sum of rulelessness:”
—Archie Randolph Ammons (b. 1926)
