Two months ago, I participated in the Imagination Summit held in Japan for the first time and prepared to go home after the event. When I was waiting to board the plane and return to the UK, I saw a billboard for Nissan Motors - "What if the man who ran the fastest in the world could be faster?" I thought, this is an interesting question.
A few weeks later, the engineering team's colleagues sent me an email telling me that the MIPS P5600 has become the No. 1 in the CoreMark ranking with a record-breaking 5.6 CoreMark/MHz per CPU score.
The world's fastest single-threaded CPU runs faster!
Its performance improvement is not an accident. Just like Nissan, the pursuit of perfection has always been our goal, even though we are already the best in the industry; the P5600 is now the new champion of CoreMark, breaking the highest score ever created by our award-winning MIPS proAptiv processor.
This result has been certified by EEMBC. EEMBC is a leading and long-established embedded processor benchmarking organization responsible for designing and maintaining CoreMark benchmarks. You can find a complete list of certification results on their website.
Looking closely at this new result, we found that the MIPS P5600 CPU offers up to 20% better performance than its directly competing products, and the area is significantly reduced.
MIPS P5600 delivers up to 20% higher raw performance in a smaller area
The CoreMark/MHz t score of the MIPS P5600 is even higher than Intel's desktop CPU products. For example, the Intel Core i7-2640M processor can reach 14513.79 CoreMark at 2.8GHz, which is 5.18 CoreMark/MHz - about 10% lower than the latest result of the MIPS P5600.
Among all licensable CPUs, the MIPS P5600 has the highest and proven CoreMark score.
This unprecedented level of performance efficiency will further improve performance for mobile, home entertainment, networking, automotive and many other power-sensitive applications that use MIPS-based embedded processors.
More importantly, these excellent results are achieved with the latest and existing GCC compilers. Whether it's the partner's source code or Imagination's SDK, all of our customers have access to this high-performance tool chain. This approach is completely different from our competitors, who must use an expensive, closed tool chain to get the best benchmark score. Conversely, Imagination's focus on building an open ecosystem that delivers performance quickly and efficiently is an important consideration for reducing time-to-market for mobile and embedded applications.
Introduction to MIPS P5600
The P5600 is a member of the MIPS Warrior P-class processor family and is designed to deliver ultimate performance for mobile and embedded applications.
MIPS P5600 features powerful, feature-rich microarchitecture design
The P5600 is a 32-bit CPU based on the MIPS architecture Release 5 and includes several unique features:
Fast 128-bit SIMD engine: accelerates multimedia processing and other matrix-based operations. Complete hardware virtualization technology: Supports multiple fully independent, parallel-running client operating systems. Enhanced security: For consumer and enterprise applications, this feature includes the ability to support multiple TEEs (Trusted Operating Environments) on a single CPU. Best-in-class advanced branch prediction mechanism, TLB page table high-speed hardware for optimal performance, and instructional bonding that can double performance for memory-intensive data movement conventions. Enhanced Virtual Addressing (EVA): More flexible use of virtual address space for easy and efficient use of memory; Extended Physical Addressing (XPA) takes advantage of up to 1TB of memory capacity (40bits).This high-end MIPS CPU is also one of our third-generation multi-issue, out-of-Order (OoO), fully synthesizable processors. The figure below shows the evolution of the high-performance MIPS CPU for a long time, from 74K and proAptiv to today.
Evolution of high-end 32-bit MIPS CPU
The MIPS P5600 adds several feature enhancements to the previous generation of proAptiv CPUs, including enhanced extraction efficiency, reduced L2 cache latency, and pre-fetching capabilities. In addition, cache replay and memory disambiguation have been improved to improve real-world performance (such as memory replication performance).
We are very proud of the record-breaking performance of the new MIPS Warrior CPU. This result is based on our long-term design of a high-performance MIPS CPU. In the future, the evolution of the instruction set architecture (such as Release 6) and the continuous innovation of the memory subsystem and micro-architecture will make this product better and achieve better results.
By combining MIPS Warrior CPUs, PowerVR Multimedia IP, and Ensigma Connectivity IP, system engineers will be able to develop state-of-the-art embedded processors that deliver best-in-class performance with lower power and smaller footprints.
To say it, today's technology is the same day by day. In the past few years, optical fiber was still an advanced term, and the price of optical fiber equipment was also scary. Nowadays, optical fiber has begun to spread widely, and the price of optical fiber equipment has dropped with the development of technology. At the same time, with the development of technology, there are more and more vocabulary, such as the PoE-ONU we are going to talk about today.
Advantages of PoE-ONU
Over the years, with the development of projects such as "light-in-copper-retreat" and "fiber-to-the-home", the popularity of ONUs has also become higher and higher. Friends who have worked on PON networks basically know ONU, which is an access terminal device used in PON network, which is equivalent to the access switch in our usual network.
The PON network is a passive optical network. The reason why it is said to be passive is that the optical fiber transmission between the ONU and the OLT does not require any power equipment. The PON uses a single optical fiber to connect to the OLT, and then the OLT connects to the ONU. The use of PON technology for networking can save half of the optical fiber, and the transmission distance is longer.
Although some expenses have been saved, can we save a little more? of course can! With the development of technology, more and more devices are connected to ONU. Many of these devices require power supply. As a result, the wiring is complicated and the operation and maintenance of the devices also require a lot of manpower. In some special environments, the inconvenience of power supply is even worse.
