  • Page 11: Unified Memory Architecture

    Motherboard Functional Specification 1.2 Unified Memory Architecture The STPC Atlas makes use of a tightly coupled Unified Memory Architecture (UMA), where the same memory array is used for CPU main memory and graphics frame-buffer. This means a reduction in total system memory for system performances that are equal to that of a comparable frame buffer and system memory based system, and generally much better, due to the higher memory bandwidth allowed by attaching the graphics engine directly to the 64-bit processor host interface running at the speed of the processor bus rather than the...

The height and width of the flat panel are programmable through configuration registers up to a size of 1024 by 1024. By default, lower resolution images cover only a part of the larger TFT panel. The STPC Atlas allows the user to expand the image vertically and horizontally in text mode by inserting programmable blank pixels.
