Called CXM, at least some support 4K resolution and at least some support 10-bit RGBA and YUV 'HDR (High Dynamic Range) operation.
“CXM GPUs boast almost 50% higher performance in the same area silicon than IMG BXM cores,& #8221; according to the company, claiming: "CXM contains the smallest GPU on the market to support HDR."
The CXM-2-64 is the “smallest GPU to support native HDR” and is designed for wearable devices, SmartHubs or regular set-top boxes.
CXM-4-64 is designed for SmartHub, set-top boxes or regular digital TVs.
CXM-4-128 is designed for premium digital TVs.
Another couple of features found among these GPUs are '4xMSAA' for text and image antialiasing, 'TFBCv2' framebuffer compression for lossy or lossless compression.
“CXM is supported by software that supports API trends, including Vulkan 1.3, and has been optimized for CPU architectures including Arm and RISC-V,” ; said Imagination.
TFBCv2 frame buffer compression will be demonstrated at RISC-V Con Shanghai and RISC-V Con Beijing.
