Android is currently supporting three processor architectures: ARM, Intel, and MIPS. ARM is currently in the industry's leadership, but Intel and Imagination Technologies have capacity to provide alternatives. Therefore, in the industry, these three major manufacturers will compete for a piece of effort in the process of moving the mobile processor to 64 bits.
In fact, the 64-bit architecture of Intel and MIPS was born for many years. The 64 MIPS chips have also gone through 20 years, so the two companies are not strange to 64-bit calculations. Angfeng Network September 3, just recently, Imagination Suddenly promotes a new 64-bit processor MIPS I-Class i6400 CPU series, and said that the series of processor applications is very extensive, covering mobile devices to big data. Server center field. This means that many embedded devices, mobile devices, digital consumer devices, communication network devices, and storage products, etc. of the future are likely to see the trace of the series of chips.
I6400 CPU is a new option for Android platform
In June Google officially released the Android L operating system, the new version of the new version of the system has supported the processor of all three architectures, including support of 64-bit MIPS chips. I6400 CPU also has a large number of new instruction features for Android optimization, especially several key points on the system, including JIT compilation, JavaScript, PIC and web browsing, etc.. Therefore, OEM vendors can safely use I6400 CPU to develop smartphones and tablets, and their finished equipment is fully compatible with Android.
I6400 CPU is the most leading 64-bit processor in the mobile field
The MIPS I6400 CPU processor's architectural code Warrior provides a lot of important hardware features, iMagination, the industry's first integration of 64-bit architectures, hardware virtualization IP core, support multi-thread, multi-core and multi-cluster (Multi-Cluster Coherent Processing) provides an extendable processor product, and is a comprehensive competitor in terms of instruction set, performance, power consumption, core area.
Specifically, in terms of performance imagination, I6400 processor is 50% higher than the competitor performance indicator, and DMIPS is 30%. In the multi-threaded test, the cluster area increases by less than 10%, the increased second thread has increased by 40-50% in the industry-wide reference test specint and Coremark.
Equipment diversity based on I6400 CPU: N core as desirable
According to reports, the design of smartphones and tablets based on this series of chips can be flexible to provide a variety of different competitive grades. Simply put, I6400 CPU can design in combination in a variety of threads, kernels, and clusters, each cluster specifies up to 6 kernels, and a chip can have 64 clusters, so the built chip can be easily met. Different price and performance standards. It is not difficult to calculate, a processor can reach 384 core. Although it is impossible to carry 384 core processors on a smartphone, this does indicate the flexibility of I6400 CPU design.
At the same time, MIPS i6400 CPU also supports hardware multi-thread technology, with a maximum of four hardware threads each, the name of this technology is synchronous multi-thread (SMT), supporting can be executed from multiple clock cycles in a CPU core Multiple instructions of threads. Other features include the Powergearing power management system. With this system, OEM vendors can design a dedicated processor by adjusting the frequency and voltage required for each kernel in the cluster, and the system also supports the internal nuclear cluster without working. Enter sleep state.
I6400 CPU officially debut next year
Imagination Executive Vice President and Market Marketing Tony King-Smith said MIPS i6400 CPU is very suitable for the next generation of smartphones and tablets. It is currently mandated with multiple partners to create different versions of I6400 series chips. It is expected to fully open authorization from December this year. This means that starting at the beginning of 2015, the age of 64-bit hardware mobile devices will really arrive, and the manufacturer of 64-bit chips can not only have ARM or Intel.
