今天痞子衡给大家介绍的是实抓Flash信号波形来看i.MXRT的FlexSPI外设下AHB读访问情形。 上一篇文章 《实抓Flash信号波形来看i.MXRT的FlexSPI外设下AHB读访问情形（有预取）》 里痞子衡抓取了Cache关闭但Prefetch开启下的AHB读访问对应的Flash端时序波形图，我们知道了FlexSPI ...

The block of memory that is transferred to a memory cache. The cache line is generally fixed in size, typically ranging from 16 to 256 bytes. The effectiveness of the line size depends on the ...

Since the earliest days of microprocessors, system designers have been plagued by a problem in which the speed of the CPU's operation exceeded the bandwidth of the memory subsystem to which it was ...

Scaling processing performance beyond the frequency and power envelope of single core systems has led to the emergence of multi-core clusters. Data access management within such processing systems ...

If multiple devices, such as the CPU and peripherals, access the same cacheable memory region, cache and memory can become incoherent. This is illustrated in Figure 7. Suppose the CPU accesses a ...

Editor's Note: Multicore architectures find use across a diverse range of applications thanks to their performance and efficiency. By combining several general-purpose MCU cores — or MCU cores and ...

Open Core Protocol (OCP) [1][2] is a common standard for Intellectual Property (IP)core interfaces. OCP facilitates IP core plug-and-play and simplifies reuse by decoupling the cores from the on-chip ...
