Access to a collective resource in which low priority functions are grouped, read accesses of the group being given higher priority than write accesses of the group
Abstract:
The invention relates to a functional system comprising a set of functions (F, F′) which are to access a collective resource (RSRC), the system including an interface (INT) arranged to implement an access scheme (AS) including at least one state (I) defined by an order of priority for an arbitration according to which the functions (F, F′) can access the collective resource (RSRC), the state (I) being characterized in that, for at least one set of at least two functions (F), the access possibilities in read mode (F_R) and the access possibilities in write mode (F_W) have different priority levels, the access possibilities in read mode having consecutive priority levels higher than the priority levels of the access possibilities in write mode.
Abstract(Chinese):

本发明涉及一种包括一组功能（F，F'）的功能系统，其功能是要访问集体资源（RSRC），所述系统包括布置成实现包括至少一个的接入方案（AS）的接口（INT） 状态（I）由仲裁的优先顺序定义，根据该顺序，功能（F，F'）可以访问集体资源（RSRC），状态（I）的特征在于，对于至少一组在 至少两个功能（F），读取模式（F_R）的访问可能性和写入模式（F_W）中的访问可能性具有不同的优先级，读取模式下的访问可能性具有比访问可能性的优先级更高的连续优先级 在写入模式。
