KMS主要负责显示相关功能,在DRM中将其进行抽象,包括:CRTC、ENCODER、CONNECTOR、PLANE、Framebuffer、VBLANK、property;它们之间的关系如下图所示: 以HDMI接口为例说明,Soc内部一般包含一个Display模块,通过总线连接到HDMI接口上; Display模块对应CRTC; HDMI接口对应Connector; Framebuffer对应的是显存部分; Plane是对Framebu...
PURPOSE: To improve the system performance with a small number of cache memories by connecting a high speed data cache memory SRAM to a high density DRAM on the same chip by accessing an external memory. CONSTITUTION: Addresses of MA0-MA9 are latched by a row address buffer 74 at a RAS...
performance (version 1.7 over version 1.6) are attributable in part to newer processor chips assigning a bigger portion of L1–L2 cache to I/O (and DDIO allows the NIC to write buffer descriptors to that cache24). This creates a high degree of cache locality and size dependency for ...
Main Memory,- BRUCE R. CHILDERS, University of Pittsburgh A DRAM bank is a 2D array of cells: rows x columns Banks receive commands and operate independently A "DRAM row" is also called a "DRAM page" A "sense amplifier" is also called a "row buffer" In an SDRAM how do address rows...

E.g., reading an MMIO register might clear a buffer, and writing may output something over a bus. I actually don't think either of those are problems in this case. This is really just shared memory, and normal shared memory constructs should be fine. We want something that is volatile,...
