pooled memory
解釋
池內存，用來標識核心函數類別的前綴-
After giving all - sided analysis and evaluation on kinds of memory allocation pattern, it designs rtps _ cached _ allocator, a pooled memory allocator which can decrease the overhead resulted from the general dynamic heap allocation, in order to improve the dynamic performance of a system and meet the de mand of qos predictability. a memory pool management framework, mpmf, is also shown
在全面分析總結各種內存分配模式及其優缺點與適用環境的基礎上，針對實時響應系統對動態性能和qos可預測性的需求，設計實現了一個能夠有效減少內存分配開銷的池式分配器rtpsmachemllocator ，提出了一個內存池管理框架mpmf 。 -
Following the architecture description of rtps middleware, two critical implementation issues are carried out : the first, object - oriented multi - threaded architecture. to avoid negative effect brought by the block, and to improve the realtime responsive ability of the system, we decouple the event processing from its transportation ; the second, pooled memory allocationjn order to decrease the time - and - space overhead due to dynamic memory allocation, thus to improve the dynamic performance of the realtime publish - subscribe system and the predictability of runtime end - to - end qos, we adopt the pooled allocation to change many dynamic system calls into one static system call and several user interface calls in fixed time
通過將事件的輸送與處理解耦以避免阻塞所帶來的影響、改善系統的實時響應能力，通過面向對象的多線程並發以支持異步事件的實時並發處理並獲得系統結構上的靈活性；其二，池式內存分配。通過內存池分配方式將客戶的大量動態系統調用轉化為一次靜態系統調用和數次固定時間的用戶介面調用以減少動態內存分配的時空開銷，從而改善實時發布-訂閱系統的動態性能與提高其運行時端對端服務質量的（ end - to - endqos ）可預測性。
