Combined branch target and predicate prediction
Embodiments provide methods, apparatus, systems, and computer readable media associated with predicting predicates and branch targets during execution of programs using combined branch target and predicate predictions. The predictions may be made using one or more prediction control flow graphs which represent predicates in instruction blocks and branches between blocks in a program. The prediction control flow graphs may be structured as trees such that each node in the graphs is associated with a predicate instruction, and each leaf associated with a branch target which jumps to another block. During execution of a block, a prediction generator may take a control point history and generate a prediction. Following the path suggested by the prediction through the tree, both predicate values and branch targets may be predicted. Other embodiments may be described and claimed.Board of Regents, University of Texas Syste

Gbit/second lossless data compression hardware
This thesis investigates how to improve the performance of lossless data compression hardware
as a tool to reduce the cost per bit stored in a computer system or transmitted over a
communication network.
Lossless data compression allows the exact reconstruction of the original data after
decompression. Its deployment in some high-bandwidth applications has been hampered due to
performance limitations in the compressing hardware that needs to match the performance of the
original system to avoid becoming a bottleneck. Advancing the area of lossless data compression
hardware, hence, offers a valid motivation with the potential of doubling the performance of the
system that incorporates it with minimum investment.
This work starts by presenting an analysis of current compression methods with the objective of
identifying the factors that limit performance and also the factors that increase it. [Continues.
