High-Level Procedural Abstraction for Reducing Size of Object Code
Abstract
As the functions of an embedded system become more
and more complex, the resources demanded by an embedded
system increase by a lot in recent years, although
the resources are always limited in practice.
One of the eff ective methods proposed to reduce the
code size is the procedural abstraction, which is usually
applied at the lower levels, such as the assembly
level, or the machine code level. Since more and more
applications for embedded systems are developed in
high-level languages like C, C++, and Java, it is natural
that we may reduce the size of object code with applying
procedural abstraction at the high-level source
code. In this talk, we present our proposed criteria for
high-level procedural abstraction in order to eff ectievly
reduce the size of object code. We design a new compiler
optimization based on the criteria such that the optimized
object code is guaranteed to have a reduced size.
We implement the proposed optimization in a simple
C-to-Thumb compiler. We will show the benchmarks
of the experiments on our new optimization at the end
of the talk.
