One of them, attributed to Niklaus Wirth, states that software is slowing
faster than hardware is accelerating-a testimonial to the irony of modernday system design. The “slowing down” in Wirth’s law can refer to both the
run-time performance as well as software development time. Due to time-tomarket pressure, the software designers do not have the luxury of optimizing
the code. Software development for modern systems often happens in parallel
to the development of the hardware platform, using simulation models of
the target hardware. There is increased pressure on software developers to
reuse existing IP, which may come from multiple sources, in various degrees
of softness. Compilers and software optimization tools either do not exist, have
limited capabilities, or are not available during the crucial periods of system
development. Due to these reasons, application software development is a slow
and daunting task, rarely permitting the use of advanced features supported
in hardware due to lack of automated tools. It is quite common for software
developers (e.g., video games) to resort to manual assembly-language coding.
