CMake generates configuration files for other build tools based on CMake-specific configuration files. The other tools are responsible for more directly building; using the generated files. A single set of CMake-specific configuration files can be used to build a codebase using the native build tools of multiple platforms. [4]
For #include guards to work properly, each guard must test and conditionally set a different preprocessor macro. Therefore, a project using #include guards must work out a coherent naming scheme for its include guards, and make sure its scheme doesn't conflict with that of any third-party headers it uses, or with the names of any globally visible macros.
Cache control instructions are specific to a certain cache line size, which in practice may vary between generations of processors in the same architectural family. Caches may also help coalescing reads and writes from less predictable access patterns (e.g., during texture mapping ), whilst scratchpad DMA requires reworking algorithms for more ...
The total number of sets in the cache is 1, and the set contains 256/4=64 cache lines, as the cache block is of size 4 bytes. The incoming address to the cache is divided into bits for offset and tag. Offset corresponds to the bits used to determine the byte to be accessed from the cache line. In the example, there are 2 offset bits, which are ...
Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.
Cache prefetching can be accomplished either by hardware or by software. [3]Hardware based prefetching is typically accomplished by having a dedicated hardware mechanism in the processor that watches the stream of instructions or data being requested by the executing program, recognizes the next few elements that the program might need based on this stream and prefetches into the processor's ...
A cache has two primary figures of merit: latency and hit ratio. A number of secondary factors also affect cache performance. [1] The hit ratio of a cache describes how often a searched-for item is found. More efficient replacement policies track more usage information to improve the hit rate for a given cache size.
The number of L2 sets must be greater than or equal to the number of L1 sets irrespective of L2 associativity. All reference information from L1 is passed to L2 so that it can update its replacement bits. One example of inclusive cache is Intel quad core processor with 4x256KB L2 caches and 8MB (inclusive) L3 cache. [3]
