Mongoose 1 (M1) is an ARM microarchitecture designed by Samsung for their consumer electronics. This was Samsung's first in-house developed high-performance low-power ARM microarchitecture.
Contents
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.
Process Technology
M1 was fabricated on Samsung's 14 nm process.
Architecture
The M1 is Samsung's first in-house design from scratch.
- ARM v8.0
- 2.6 GHz clock frequency
- 2.3 GHz for multi-core workloads
- Sub 3-watt/core
- 14 nm process (FinFET)
- Core
- Advanced branch predictor
- 4-way instruction decode
- Most instructions map to a single µOP, with a few exceptions
- 4-way µOP dispatch and retire
- Out-of-order execution
- Out-of-order load and stores
- Multistride/multistream prefetcher
- Low-latency and low-power caches
