# KOMDIV-32

The KOMDIV-32 (Russian: КОМДИВ-32) is a family of 32-bit microprocessors developed and manufactured by the Scientific Research Institute of System Development (NIISI) of the Russian Academy of Sciences. The manufacturing plant of NIISI is located in Dubna on the grounds of the Kurchatov Institute. The KOMDIV-32 processors are intended primarily for spacecraft applications and many of them are radiation hardened (rad-hard).
These microprocessors are compatible with MIPS R3000 and have an integrated MIPS R3010 compatible floating-point unit.
