F8 – an 8 bit architecture designed for C and memory efficiency [video] (fosdem.org)
Even in modern devices, 8-bit processors are found, but the architectures used are often not well-suited to programming in high-level languages, such as C. E.g. MCS-51 (8051, 8052) based microcontrollers in the Realtek WiFi chipsets. The f8 is an architecture based on the experience and lessons learned from maintaining Small Device C Compiler (SDCC) and the many 8-bit architectures it supports.
