Outline In this study, we explore the performance limits of these TAGE-SC-L predictors for respectively 8Kbytes and 64Kbytes of storage budget. For a 8KB storage budget, our submitted predictor used most of its storage budget on the TAGE predictor, features a very small loop predictor LP and...
The multichannel selection is formed by combining a demultiplexer and a multiplexer together in the fiber-loop mirror. The structure is able to filter out the amplified spontaneous emission that saturates the amplifier gain in the small signal regime. The maximum average gain of 47.2 dB is......
