The PlayStation Portable, a gaming handheld from over twenty years ago, was never built for modern web browsing speeds, especially given its 333 MHz MIPS32 CPU and 64 MB of RAM. Yet, Tilefinch manages to squeeze in a fully functioning modern web browser right on the device without relying on proxies. It achieves this feat by combining a custom-built layout engine, Lexbor, with QuickJS for JavaScript, alongside taking advantage of the PSP's hardware-accelerated video decoding. This blend of software and built-in hardware capabilities pushes the PSP far beyond its original web browsing intentions.
Tilefinch’s development raises fascinating questions about the boundary between low-end SoCs and high-end microcontrollers. If a two-decade-old gaming console can run a modern browser so efficiently, could similar browsers be tailored for very low-power devices like the ESP32-P4? What software optimizations and hardware tricks would be necessary to sustain smooth browsing experiences in such constrained environments?
