Eben Upton Hints at the Next Raspberry Pi Silicon Chip: Lightweight, TinyML Edge AI Accelerators The next part from Raspberry Pi's in-house ASIC team may concentrate on lightweight tinyML accelerators capable of 4-8MACs/clock. Eben Upton has hinted at a possible second in-house silicon design to come from the Raspberry Pi application-specific integrated circuit (ASIC) team, as a follow-up to its barnstormingly successful RP2040 microcontroller: Lightweight, low-power accelerators for edge AI and tinyML. Raspberry Pi launched two firsts earlier this year: The Raspberry Pi Pico microcontroller development board, and the RP2040 microcontroller which drove it. Although the company has long designed its own single-board computers, a shift to microcontrollers came as a surprise â as did the news that the chip was a product of its emerging-from-stealth in-house ASIC design team.
