Configuration reads and writes can be initiated from the CPU in two ways: one legacy method via I/O addresses 0xCF8 and 0xCFC, and another called memory-mapped configuration. The legacy method was present in the original PCI, and it is called Configuration Access Mechanism (CAM). It allows for 256 bytes of a device's address space to be reached indirectly via two 32-bit registers called PCI CONFIG_ADDRESS and PCI CONFIG_DATA. These registers a… Web9 mrt. 2024 · In hybrid ARM architectures, a so called memory map is implemented, with a different address map configuration of 32-bit, 36-bit, and 40-bit that depends on the requirement of System On a Chip (SoC) address space with extra DRAM. The Memory Map grants interface with SoC design, while having most system control on a high level coding.

WebConfiguration space registers are mapped to memory locations. Device drivers and diagnostic software must have access to the configuration space, and operating systems typically use APIs to allow access to device configuration space. WebThe attainable worst-case bandwidth, latency, and power of the memory depend largely on memory map configuration. Sharing SDRAM amongst multiple applications is challenging, since their requirements might call for different memory maps. This paper presents an exploration of the memory-map design space.
