RISC V friendly smallest GPU VLSI IP for consumer electronics SoCs
Date: 25/05/2023
SoC VLSI IP vendor Imagination has announced its new IMG CXM graphic processors (GPU) family for designing SoC chips for consumer electronics applications, and display systems in smart home platforms. CXM-2-64, one of the member of this new GPU IP family takes very less real-estate space on SoC, where it supports HDR user interfaces natively. This processor core also gels well with other RISC V processor cores on your SoC platform.
These GPUs are designed to highly responsive super-fine graphic displays used in digital television, smart home systems, providing smartphone display like experience, where content providers can provide 4K and HDR movies with a very responsive user interface.
James Chapman, Chief Product Officer, Imagination Technologies, says, “These new CXM GPUs are a significant step up from our widely licensed IMG BXE and BXM range. We’ve taken that highly scalable, area-efficient architecture, boosted its performance density, and added key features, such as native support for HDR, that will transform user experiences and propel our customers to success in the consumer market. I expect to see CXM GPUs deployed in devices as diverse as wearables and premium 8K DTVs.”
Below are the members of Imagination CXM family:
CXM-2-64: the smallest GPU to support native HDR applications, suitable for wearable devices, smart home hubs, or mainstream set-top boxes.
CXM-4-64: an efficient core ideal for integrating into smart home hubs, set-top boxes or mainstream DTVs.
CXM-4-128: a performance dense option for premium DTVs.
Some of the features listed by the company includes:
Smoother images: These graphic processor cores support 10bits RGBA / YUV deliver an HDR graphical user interface with images with less visible banding. 4xMSAA efficiently smooths the outlines of texts and images.
Advanced bandwidth management: TFBCv2, the new generation of Imagination’s Tiny Frame Buffer Compression, delivers higher-quality lossy / lossless compression and an additional compression level (37.5%) for improved design flexibility. It is also CXM series provide option to SoC makers to combine its GPU compute capabilities with additional AI hardware to bring advanced functions, such as gesture recognition, to consumers.
IMG CXM GPU range boasts nearly a 50% uplift in performance density compared to the IMG BXM range, opening up more performance in the same silicon area, claims Imagination.
The IMG CXM is supported by Vulkan 1.3, and has been optimised for several leading CPU architectures including Arm and RISC-V application processors. Imagination says its GPUs are the perfect addition to RISC-V projects and are silicon-proven, shipping in multiple products across a wide range of use cases.
Dr. Charlie Su, CTO and President of Andes Technology says: “The RISC-V ecosystem is growing rapidly. To continue its growth and showcase the many possible ways it can be deployed, we partnered with Imagination to provide a quick and easy path to validated GPU and CPU IP blocks that can reduce SoC design time, risk, and cost for our customers. With Imagination’s flexibly designed GPU, and our AndesCore high-performance, low-power RISC-V CPU, we are able to satisfy the requirements for display-oriented SoC in a short time and generate the optimum configuration.”
