Is an accumulator the same as a cache memory? No, they are different concepts. An accumulator is a register or variable used for temporary storage of data during calculations, while cache memory is a specialized high-speed storage that holds frequently accessed data to improve overall system perf...
In the last decades, the increasing amount of resources in embedded systems has been leading them to the point where an efficient management of these resources is mandatory, especially for the memory subsystem. Current MPSoCs have more than one application running concurrently. Hence, it is importa...
cache memory is a type of data storage used to store frequently accessed information for faster response time. it's a vital component in computer systems, and it's used to improve system performance. but what exactly is cache memory and how does it work? let's take a look at the basics...

A cache memory system for use in a motion estimation system is disclosed. The system includes: a first cache memory defined in terms of a first width and a first height, and a second cache memory defined in terms of a second width and a second height, wherein said second height is less...
A cache holds commonly used memory data. The number of data words that it can hold is called the capacity, C. Because the capacity of the cache is smaller than that of main memory, the computer system designer must choose what subset of the main memory is kept in the cache. When the ...
Thus, the placement of data within the memory system, or virtual memory system (depending on whether the caches are physically indexed or virtually indexed), is crucial to reducing the number of conflict misses to the minimum possible. The problem is that doing this—placing data in memory in...
