Imagination Technologies (IMG.L) has introduced PowerVR Series7, the latest generation of the PowerVR Rogue GPU architecture and an entire line-up of GPUs that scale from 16 to 512 arithmetic logic unit (ALU) cores, providing scalability, efficiency and performance.
PowerVR Series7 is architected for the broadest range of next-generation products from wearables and IoT through automotive, mobile and consumer electronics devices, up to high-performance GPU compute. Configurable, scalable GPUs address market requirements across these segments, with features such as full hardware virtualization and Android Extension Pack (AEP) support with hardware tessellation, as well as proven features such as geometry shaders, PVR3C triple compression technology for bandwidth/power savings, and full ASTC (adaptive scalable texture compression) support. Series7 also includes Imaginationís advanced PowerGearing technology for dynamic core and cluster level power management.
The PowerVR Rogue architecture is scalable via threads, cores and clusters. Rogue uses clusters of up to 32 multi-threaded ALU cores, working in close cooperation with dedicated texture units on the same region of the screen. This approach ensures that all accesses to memory are correlated and efficient, unlike older multi-core approaches where many cores all work in an uncoordinated way on different regions of the screen that results in many distributed accesses to memory and inefficient DRAM usage. With their scalable and efficient architecture, PowerVR Series7 GPUs provide unrivalled performance and efficiency.
Series7XT and Series7XE GPUs achieve up to a 60 percent architectural performance increase on the latest industry standard benchmarks compared to equivalent configurations of previous generation PowerVR Series6XT/6XE GPUs, maintaining and extending PowerVRís reputation as the most efficient, highest performance, lowest power GPU. Application developers can take advantage of the significant parallel processing power in Series7 for both graphics and GPU compute tasks. Series7 architectural enhancements include:
- Instruction set enhancements including added co-issue capability, resulting in improved application performance and increased GPU efficiency
- New hierarchical layout structure that enables scalable polygon throughput and pixel fillrate improvements in addition to increased clock frequencies
- GPU compute setup and cache throughput improvements resulting in up to 300 percent better parallel processing performance
Series7XE GPUs are based on a single scalable cluster of up to 32 multi-threaded multi-tasking ALU cores, enabling the latest games and apps on power and cost constrained devices such as entry-level to mid-range mobile devices, TVs, set-top boxes and wearables, as well as a broadening range of products such as photocopiers, printers, consumer and other enterprise devices which increasingly require high-quality UIs at competitive price points. Series7XE are the smallest GPUs that are AEP compatible, yet like the high-performance Series7XT family can be configured with options such as 10-bit YUV support for HEVC, making them ideal for applications like entry level UltraHD TVs. GPUs include the GE7400 with 16 cores and the GE7800 with 32 cores.
In an increasingly connected world, security is a growing concern, with any system only as secure as its weakest link. This is true at the macro level, device level and SoC level. Within the SoC, especially as the industry moves to heterogeneous processing architectures, each processing unit must have built-in security. Imaginationís forthcoming heterogeneous security architecture is designed to address the privacy and security needs of evolving and emerging connected applications. As part of this, PowerVR Series7 joins the MIPS Warrior CPUs in supporting full hardware virtualization, and is optimized to support multiple independent security contexts and execution domains.
CPU-agnostic hardware virtualization in the GPU enables customers in segments such as automotive to build systems where the dashboard and infotainment system can run independently and reliably on the same platform. For Android phones and tablets, hardware virtualization can keep a userís personal banking data separate from other data such as health information collected by a wearable device.
With Series7, users can select the specific features they need for their design, and avoid the cost of including features they donít need:
- Android Extension Pack (AEP): customers targeting Android applications can leverage the AEP with full hardware tessellation and native OpenGLģ ES 3.1 support* in the new GPUs. The new pack ensures maximum content compatibility with the Android 5.0 ĎLollipopí release.
- DirectX 11 Feature Pack: for customers targeting Microsoft operating systems, this pack for Series7XT GPUs provides a full DirectX 11.2 feature set, building on Imaginationís many years of market-proven support for DirectX.
- OpenCL FP64 Feature Pack: for customers leveraging Series7XT for high-performance server compute, this pack provides a scalable 64-bit floating point co-processor per cluster.
