Fully associative cache mappingis similar to direct mapping in structure but enables a memory block to be mapped to any cache location rather than to a prespecified cache memory location. Set associative cache mappingcan be viewed as a compromise between direct mapping and fully associative mapping ...
在一个操作系统实现中,Memory Allocator是一个非常重要的组成部件,其设计异常复杂。有一些人在努力寻求最优的,通用的分配管理原则,虽然最优和通用几乎很难划等号。通用原则有通用原则的适用场合,专用的定制原则也有其存在的必要,没有一个绝对的准则。通常在一个Memory Allocator的设计中需要关注自身的运行效率,如Footpr...

从物理内存上面,就是 OS的Memory Management的Allocator或者应用程序,例如,通信系统的Data Path的内 存管理了。然后通过一个个的mapping,最后落得某一个包厢(Set)的长凳子(Way) 上。 这样OS与CPU之间的语义就存在了一定程度的Aware了。 下图所示为在上几节中,given 一个2M的4Way SET-Assoc L2 Cache,4K的物理P...
Abstract:In order to improve the unified shading processor efficiency of the mobile graphics processor and reduce the number of accesses between it and the off-chip memory, this paper presents a four-port texture cache architecture. This architecture uses texture mapping based on Mipamp algorithm an...
A computer system can unify main memory and cache memory, wherein fully associative mapping method can be utilized to cover a whole range of cache and main memory. In the system, central processing unit (CPU) sends a data request and access the cache portion of the unified cache and memory...

Firmware generally resides in read-only memory (ROM) on the device. Flash Translation Layer Flash Translation Layer (FTL) organizes and manages host data, enables host data to be allocated to NAND flash chips of SSDs in an orderly manner, maintains the mapping relationship between logical ...
The problem even intuitively resembles 3-COLOR (see Figure 3.61, which gives a picture of the transformation, where memory object ox corresponds to vertex vx in the graph). Any legal coloring of the vertices corresponds to a legal mapping of the objects to the memory space, and any legal ...
