London, UK – 2nd September, 2014 – Imagination Technologies (IMG.L) announces the highly-efficient MIPS I-class I6400 CPU family, the first IP cores to combine a 64-bit architecture and hardware virtualization with scalable performance through multi-threading, multi-core and multi-cluster coherent processing. Its extraordinary feature set and performance/power/area leadership place the I6400 far ahead of the competition, enabling customers to implement a smaller core at the same performance, or a faster core in the same area.
MIPS Warrior I-class processor cores set a new standard for mainstream 64-bit processing in applications including embedded, mobile, digital consumer, advanced communications, networking and storage—the broadest set of applications ever addressed by a single MIPS core family.
Says Tony King-Smith, EVP marketing, Imagination: “This is the MIPS Warrior core that many have been waiting for. As the industry moves toward instruction set neutrality, customers can now choose a CPU based on its technical superiority. The I6400 is more efficient, flexible and scalable than the competition, and its feature set clearly lends itself to the needs of a wide range of next-generation applications including smartphones and tablets. We know that unique features like multi-threading provide significant advantages for many applications, and customers already using this technology agree. Unsurprisingly, we’ve already secured licensees for the I6400 across multiple markets.”
Says Jim McGregor, founder and principal analyst, Tirias Research: “To address the ongoing evolution in applications from IoT to mobile to networking and storage, companies need to select scalable platforms that can future-proof their designs. With 64-bit, multi-threading, and multicore/multi-cluster support, the I6400 is designed to be a phenomenally flexible, low-power processor architecture capable of scaling across a wide range of applications. Imagination now has MIPS IP cores for everything from microcontrollers to 64-bit servers, delivering choice across the range and changing the competitive dynamic in the industry.”
Inside the I6400 family of cores
· Highly efficient, scalable 64-bit performance: The I6400 will enable customers to set new price/performance points across markets. It achieves over 50% higher CoreMark performance and 30% higher DMIPS compared to leading competitors in its class*. The I6400 can be implemented across a very wide range of performance, power and area operating points and achieves high frequencies in aggressive implementations.
· Hardware multi-threading: The I6400 features hardware multi-threading technology that supports up to four hardware threads per core. Imagination’s proven MIPS multi-threading technology leads to higher utilization and CPU efficiency. The simultaneous multi-threading (SMT) technology in the I6400, which builds on the decades of combined multi-threading expertise in the MIPS and Imagination engineering teams, enables execution of multiple instructions from multiple threads every clock cycle. Preliminary benchmarking shows that adding a second thread leads to performance increases of 40-50% on popular industry benchmarks including SPECint and EEMBC’s CoreMark, with less than a 10% cluster area increase. Real-world applications such as browsers can also take significant advantage of multi-threading.
· Hardware virtualization: The I6400 joins the entire range of MIPS Warrior cores in incorporating hardware virtualization technology, providing increased security and reliability, and enabling a unified security and virtualization strategy throughout the system and across the entire SoC. As implemented in the I6400, this includes support for up to 15 secure/non-secure guests.
· Next-generation security: As part of Imagination’s unified security strategy, designed to address the privacy and security needs of evolving and emerging connected applications, the I6400 core is optimized to support multiple independent security contexts and multiple independent execution domains. This much enhanced security capability leverages technology from Imagination and its ecosystem partners and can encompass other critical components of an SoC. The solution scales to support secure content delivery, secure payments, identity protection and more across multiple applications and content sources.
· Advanced power management: With PowerGearing™ for MIPS, the I6400 features advanced power management capabilities. This includes the ability to provide a dedicated clock and voltage level to each core in a heterogeneous cluster, while maintaining coherency across CPUs so that sleeping cores only need to wake when needed.
· Efficient FPU: The proven hardware Floating Point Unit (FPU) in the I6400 supports both single and double precision capabilities relevant to general computing as well as improved control systems processing.
· 128-bit SIMD: The I6400 features 128-bit SIMD support, delivering high performance and high throughput for a wide range of tasks that can exploit the efficiencies of SIMD execution in data-parallel applications. It is built on the MIPS SIMD architecture which adheres to true RISC philosophy, with instructions defined to be easily supported within high-level languages such as C or OpenCL for fast and simple development of new code, as well as leverage of existing code. The SIMD in the I6400 supports a wide variety of integer (8, 16, 32 and 64-bit) and floating point (32, 64-bit) data types, making it highly efficient for many applications across audio, video, vision, and other computationally-intensive use cases.
Next-generation multicore coherency
The I6400 features the latest generation of the MIPS Coherency Manager fabric based on a new multicore coherent interconnect architecture. It supports multicore configurations of up to six cores per cluster where multiple cores on a single cluster can have different synthesis targets, and operate at different clock frequencies and voltages. The Coherency Manager fabric implements numerous high-performance features including hardware pre-fetching as well as wider buses and lower latencies compared to previous generations.
Scalable, multi-cluster coherency
I6400 cores are designed to be delivered in diverse combinations of threads, cores and clusters, supporting multi-cluster fabric configurations up to 64 clusters. The cores are also designed to operate in heterogeneous clusters in future SoC implementations leveraging CPUs, GPUs and other processing elements.
MIPS: the ultimate 64/32-bit architecture
Broad ecosystem of support
I6400 customers benefit from the broad ecosystem that already exists around MIPS, including software, tools and applications and the new prpl open source foundation. With founders Broadcom, Cavium, Ikanos, Ineda Systems, Ingenic Semiconductor, Lantiq, PMC, Qualcomm Incorporated and others, prpl is delivering exciting open source software for MIPS I-class and other Warrior cores with a focus on markets from IoT to datacenter.
Tools and software
A broad range of development tools and software is already available or in development for the I6400 cores, from Imagination and numerous companies across the MIPS ecosystem. In addition, the I6400 is optimized for the latest 64-bit and 32-bit mobile operating systems. The forthcoming ‘L’ release of Android includes support for 64-bit MIPS, building on long-time existing support for the 32-bit MIPS architecture. Hypervisors in development for the I-class cores will enable customers to take full advantage of hardware virtualization and enhanced multi-context security capabilities.
Getting started with the I6400 core
One of the first projects completed through the prpl open source foundation is support for the MIPS64 r6 architecture in the QEMU open source emulator, currently available at http://github.com/prplfoundation. With QEMU, developers can get started on developing applications and software for the 64-bit I6400. More information on the QEMU working group in prpl can be found at http://wiki.prplfoundation.org/wiki/QEMU.
Imagination is already engaged with multiple lead I6400 licensing partners, with general availability scheduled for December 2014. Contact email@example.com for more information.
