Game Boy Advance Architecture – A Practical Analysis
An in-depth analysis that explains how this console works internally
However, rather than walking away (after all, Acorn was a competitor), both discussed the possibility of evolving the ARM3 to deliver Apple’s requirements[5], namely flexible clock frequency, integrated MMU and complete 32-bit addressing. The size of ARM’s instructions meant that hypothetical gadgets comprised of 16-bit buses with limited memory and storage - all to save cost and energy - would make the CPU inefficient and bottlenecked. Programming for the GBA shared some methodologies with the Super Nintendo but also inherited all the advancements of the early 2000s: Standardised high-level languages, reliable compilers, debuggable RISC CPUs, non-proprietary workstations for development, comparatively better documentation and… Internet access!
