Target Memory Management for Input Pointer Variables For in variables of a pragma offload the default behavior is to do a fresh memory allocation for each pointer variable.
ここではMMU(メモリー管理ユニット)の仮想化も重要な役割を果たします。
Memory management unit(MMU) virtualization plays an important role here as well.
ポインターのリダイレクトは、独自のメモリー管理関数を使用するための唯一の正しい方法です。
Redirecting the pointers is the onlycorrect way to use your own set of memory management functions.
Target Memory Management for Output Pointer Variables By default an out variable is allocated fresh memory on the target at the start of an offload and the memory is freed at the end of the offload.
This memory management scheme uses 4KB buffers as its base, but then allocates structures from within, keeping track of which pages are full, partially used, and empty.
Should this prove to be a good idea it would essentially give the GNU GRUB thecapabilities of a mini operating system with compiler, memory management and so on.
If you call your own memory functions without redirecting the pointers, the memory will get managed by two independent memory management packages, which may cause unexpected memory issues.
This vulnerability is similar to CVE-2017-5754(aka"Meltdown") but exploits an interaction between the Memory Management Unit(MMU) and the L1 Data Cache under speculation when performing virtual to physical memory address translation.
Built-in conversion of fixed-point data(HDL vectors) to MATLAB floating-point data(double, single) and integer types(HDL real to MATLAB double/single and HDL to MATLAB integer)Array transfers and efficient memory management HDL simulation time can be transferred to MATLAB Setting up MATLAB for Co-Simulation In order to setup the interface, follow the configuration procedure described below: Start MATLAB.
