PURPOSE:To accelerate speed for executing a program set in a specified area without so much lowering a hit rate at the time of returning control from the program in the specified area to a normal program concerning the instruction cache control system for an information processor realizing one ...
Data cache prefetching under control of instructio 优质文献 相似文献 参考文献 引证文献Predictability of load/store instruction latencies Due to increasing cache-miss latencies, cache control instructions are being implemented for future systems. The authors study the memory referencing behav... SG Abraham...
Cache hierarchy models can be optionally added to a Simics system, and the system configured to send data accesses and instruction fetches to the model of the cache system. Based on the cache simulation, it is possible to determine the hit and miss rate of caches at different levels of the...
The cache memory (204) comprises an L1 instruction cache (L1 I-cache) (2042) and a cache controller (2044). The L1 I-cache (2042) compr... Y Shen,L Fang,H Luo 被引量: 0发表: 2017年 INSTRUCTION PREFETCH METHOD FOR CACHE CONTROL AND SYSTEM PROBLEM TO BE SOLVED: To provide a ...
与此类似,RVWMO 还隐式地强制在加载和后续存储之间进行排序,该存储控制依赖 (control dependent) 于加载。这是为了防止因果循环,例如表 5.14 中所示,其中存储能够影响由先前加载读取的值,该值决定存储是否必须执行。值得注意的是,上述所有依赖都是指句法 (syntactic) 依赖而不是语义 (semantic) 依赖,即是否存在寄存...
At each node Bi.j, the sum of control flow going into the node must be equal to the sum of control flow leaving the node, and it must also be equal to the execution count of l-block Bi.j. Therefore, two constraints are constructed at each node Bi.j: (16)xi=∑u.vp(u.v,ij)...
CPU(Central Processing Unit):包含控制单元(Control Unit)、逻辑运算单元(Arithmetic/Logic Unit); 内存:存储指令、数据; 输入输出设备; 概念解析 CPU(Central Processing Unit) CPU,中央处理器,负责执行用户和操作系统下发的指令。此处指令,是以01二进制形式组织的机器码,在物理底层,01用来控制高低电位。
In order to control an access request to the cache shared between a plurality of threads, a storage unit for storing a flag provided in association with each of the threads is included. If the threads enter the execution of an atomic instruction, a defined value is written to the flags sto...
If the remote bus master has control of the system bus, the controller (44) prevents the CPU (48) from performing a locked write instruction sequence. If the CPU is already executing the locked write instruction sequence, the remote bus master is denied control of the system bus. 展开 ...
1,SCTLR, System Control Register,系统控制寄存器 SCTLR寄存器是系统顶层的寄存器,可以控制内存系统,其中包括Cache和MMU等,下面将简单研究关于cache和MMU的disable、enable相关操作。 ARMv7 ARMv8-aarch32: 其中主要是I,C以及M bit: I位,bit[12]:I-cache的enable,这是个全局的指令缓存使能位: ...
