Method of providing microcontroller cache memory
The cache policy for the different regions of memory within the microcontroller can be defined through the Memory Protection Unit regions with the cache configuration bits in the MPU “Attribute and Size” register (Fig. 6.22). The configuration options are shown in Table 6.3. Sign in to downloa...
• Distributed Virtual Memory (DVM) updates • Memory tagging 下面来看一个CMN总线的接口,如图1-3所示。 图1-3 CMN接口 通过上图可以看出,CMN的主要作⽤是可以互联多个CHI Master 、 ACE - lite Master ,然后通过CHI接⼝协议,做到多个Master之间的缓存⼀致性。可以看出Master(CPU)要接入CMN总线需要支...
Up to four external memory regions can be remapped with this feature. Once a region is remapped, the remap operation occurs even if the ICACHE is disabled or if the transaction is not cacheable. The cacheable memory regions can be defined and programmed by the ...

With cache partitioning in preemptively scheduled systems, the preempting task will not evict the cached memory blocks of the preempted task if both tasks use separate cache partitions. The technique can be implemented using specific hardware extensions (e.g., Intel’s Cache Allocation Technology (...

Product Brief PRELIMINARY XC2200I - iCache 16/32-bit µC for Automotive Body Applications The XC2200I microcontroller series offers a strong performance boost by inte- grating the INSTRUCTION CACHE (iCache) between the embedded Flash and the CPU. This results in a 30% higher...
The energy model by Shiue and Chakrabarti , though highly accurate, requires a wide range of inputs like number of bit switches on address bus per instruction, number of bit switches on data bus per instruction, number of memory cells in a word line and in a bit line, and so forth. ...
