    Abstract: In one embodiment, a memory that is delineated into transparent and non-transparent portions. The transparent portion may be controlled by a control unit coupled to the memory, along with a corresponding tag memory. The non-transparent portion may be software controlled by directly accessing the non-transparent portion via an input address. In an embodiment, the memory may include a decoder configured to decode the address and select a location in either the transparent or non-transparent portion. Each request may include a non-transparent attribute identifying the request as either transparent or non-transparent. In an embodiment, the size of the transparent portion may be programmable. Based on the non-transparent attribute indicating transparent, the decoder may selectively mask bits of the address based on the size to ensure that the decoder only selects a location in the transparent portion.

    Abstract translation: 在一个实施例中,描绘为透明和非透明部分的存储器。 透明部分可以由耦合到存储器的控制单元以及对应的标签存储器来控制。 非透明部分可以通过经由输入地址直接访问不透明部分来进行软件控制。 在一个实施例中,存储器可以包括解码器,其被配置为对该地址进行解码并选择透明部分或非透明部分中的位置。 每个请求可以包括将该请求标识为透明或不透明的不透明属性。 在一个实施例中,透明部分的尺寸可以是可编程的。 基于指示透明的非透明属性,解码器可以基于大小来选择性地屏蔽地址的位,以确保解码器仅选择透明部分中的位置。
