Maximum Loop Distribution and Fusion for Two-level Loops Considering Code Size
In this paper, we propose a technique combining loop distribution with loop fusion to improve the timing performance without increasing the code size of the transformed loops. We ...

Systematic Modification of Parity-Check Matrices for Efficient Encoding of LDPC Codes
An algorithm for efficient encoding of LDPC codes is presented that does not impose any restrictions on the construction of the parity-check matrices. The algorithm modifies the pa...

Code Specialization Based on Value Profiles
Abstract. It is often the case at runtime that variables and registers in programs are "quasi-invariant," i.e., the distribution of the values they take on is very skewed...
