Cache memory device having dynamically-allocated or deallocated buffers, digital data processing system comprising it and method thereof

摘要

Dynamically cache memory device that has a buffer that is assigned or released, a digital data processing system and method comprising same are disclosed. The cache memory device, or a digital data processing system includes a buffer in a portion of dynamic cache memory regardless of the address and size of the buffer is allocated and freed by the buffer, and thus can be efficiently accessed in a system using a cache memory, has the. That is, after the contents of the buffer by the write operation in the buffer is placed in the internal cache memory is defined, when the contents of the buffer to the operation to be read in order to be used for other operations, the main caused not required by the operational characteristics of a cache It can eliminate access to the memory. Therefore, it is effective to provide an intuitive and friendly programming interface to the user (user).
