{{WorkInProgress}}Modern PC graphics card integrates a processor called GPU (Graphics processing unit) that is provided by a dedicated SDRAM bank. From the functional standpoint, on DM8148 graphics processing is performed by some blocks that are integrated in the chip. They are:# High Definition Video Processing Subsystem (HDVPSS)# High Definition Vieo Image Coprocessor (HDVICP2)# SGX530 3D Graphics Engine# Imaging Subsystem (ISS)# Media controllers.These blocks are tightly coupled with main general-purpose CPU (ARM Cortex-A8) and with SDRAM. All of these entities share the system SDRAM. SDRAM is managed by sophisticated DMM/TILER module that optimizes its usage and implements priority management.
