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.

Sum Addressed Decoder - Further Optimizations: Predecode
... 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:

    Looking foolish does the spirit good. The need not to look foolish is one of youth’s many burdens; as we get older we are exempted from more and more, and float upward in our heedlessness, singing Gratia Dei sum quod sum.
