Mongoose 1 (M1) is an ARM microarchitecture designed by Samsung for their consumer electronics. This was Samsung's first in-house developed microarchitecture.
History
The Mongoose 1 (M1) microarchitecture was Samsung's first in-house design which was done entirely from scratch. A design team was assembled and in roughly 3 years, they've gone from requirements to tape-out. The design was done at Samsung's Austin R&D Center (SARC) which was founded in 2010 for the sole purpose of developing high-performance, low-power, complex CPU and System IPs. A large portion of the design team consists of many ex-AMD Austin engineers as well as ex-IBMers.
