一个提高堆栈大小的方式为按照SystemC LRM内的描述调用set_stack_size()方法。VCS提供了另外一个方法来改变堆栈大小和堆栈保护大小,是如后描述的runtime选项。不必重新编译仿真,就可以扩展堆栈大小。 Increasing Stack Size 可以通过如下VCS runtime选项来增加所有SC线程的堆栈大小: -sysc=stacksize:[0...9]+[K|...
使用-sysc=stacksize:1024k runtime开关来设置堆栈size。这和给SC_THREADS设置堆栈size是同样的开关。 因为sc_main()线程比SC_THREADS更heavier,因此VCS会给这个开关指定的值分配16次。 使用setenv VCS_SYSC_STACKSIZE 1024k 环境变量来设置堆栈size。这是上面开关的一种替代方式。这里,VCS会给指定的值分配16次。
A: IEEE p1666 specifies the set_stack_size() API to change the stack size of a thread process. However, it does not mention the default stack size of a thread process since that is an implementation detail. The same default thread stack size of 64 KB is used between the O...
The sc_spawn_options class supports the following API: void set_stack_size(int stack_size); // specify stack size for threads, ignored for methods void spawn_method(); // spawn a method process, the default is a thread process void dont_initialize(); // don’t schedule the spawned ...
用户级线程的堆栈在SystemC模拟进程的堆中通过下面的行cor->m_stack = new char[cor->m_stack_size]分配。我面临的问题发生在创建之后的堆栈保护函数中,该函数使用mprotect系统调用使页面在用户级线程堆栈之后(再次,位于Linux进程的堆中)无法访问(PROT_NONE)。来自mprotect的错误(mprotect)说,我们要保护的这个页面...

a device or set of devices is replaced by a detailed model run by a second simulator. The software stack keeps running on the Simics processors and mostly using Simics devices,while feeding realistic operation sequences to the accelerators (Liong, 2008;Khan and Wolfe, 2013). Integrating a deta...

Moreover, it manages the communication protocol and the synchronization mechanism between QEMU/OVP and Sys...
