## Summary

James Adams (CTO) and Liam Fraser (Hardware/Software Engineer) from Raspberry Pi discuss the development of the RP1 custom silicon, the success of the RP2040 microcontroller, and the architecture of the Raspberry Pi 5. They explain how RP1 acts as a Southbridge/chiplet to offload I/O functions from the main Broadcom SoC, allowing for cost and complexity reductions as process nodes shrink. The conversation covers their internal chip design tooling, sourcing strategies during the chip shortage, and the rationale for sticking with ARM over RISC-V.
