Efficient Calling Conventions for Irregular Architectures

Philipp K. Krause

We empirically evaluated thousands of different C calling conventions for irregular microcontroller architectures, and found potential for improvement over the calling conventions…

lospre in linear time

Philipp Klaus Krause

Lifetime-optimal speculative partial redundancy elimination (lospre) is the most advanced currently known redundancy elimination technique. It subsumes many previously known approa…

C for a tiny system

Philipp Klaus Krause, Nicolas Lesser

We have implemented support for Padauk microcontrollers, tiny 8-Bit devices with 60 B to 256 B of RAM, in the Small Device C Compiler (SDCC), showing that the use of (mostly) stand…

Constant-time connectivity tests

Philipp Klaus Krause

We present implementations of constant-time algorithms for connectivity tests and related problems. Some are implementations of slightly improved variants of previously known algor…

A lower bound on the tree-width of graphs with irrelevant vertices

Isolde Adler, Philipp Klaus Krause

For their famous algorithm for the disjoint paths problem, Robertson and Seymour proved that there is a function such that if the tree-width of a graph with pairs of te…

Irrelevant Vertices for the Planar Disjoint Paths Problem

Isolde Adler, Stavros G. Kolliopoulos, Philipp Klaus Krause +3

The Disjoint Paths Problem asks, given a graph and a set of pairs of terminals , whether there is a collection of pairwise vertex-disjoi…

A lower bound for the tree-width of planar graphs with vital linkages

Isolde Adler, Philipp Klaus Krause

The disjoint paths problem asks, given an graph G and k + 1 pairs of terminals (s_0,t_0), ...,(s_k,t_k), whether there are k+1 pairwise disjoint paths P_0, ...,P_k, such that P_i c…
