摘要： Power conservation via DRAM access reduction is provided by a buffer/mini-cache selectively operable in a normal mode and a buffer mode. In the buffer mode, entered when CPUs begin operating in low-power states, non-cacheable accesses (such as generated by a DMA device) matching specified physical address ranges are processed by the buffer/mini-cache, instead of by a memory controller and DRAM. The buffer/mini-cache processing includes allocating lines when references miss, and returning cached data from the buffer/mini-cache when references hit. Lines are replaced in the buffer/mini-cache according to one of a plurality of replacement policies, including ceasing replacement when there are no available free lines. In the normal mode, entered when CPUs begin operating in high-power states, the buffer/mini-cache operates akin to a conventional cache and non-cacheable accesses are not processed therein. In one usage scenario, data retained in the buffer/mini-cache is graphics refresh data maintained in a compressed format.
摘要翻译：通过DRAM访问减少的功率节省由在正常模式和缓冲模式下选择性地操作的缓冲器/微型缓存器提供。在缓冲模式下，当CPU开始在低功耗状态下运行时，与缓存/微型缓存进行匹配的非缓存访问（例如由DMA设备产生的）与指定的物理地址范围匹配，而不是由存储器控制器和DRAM。缓冲/微型缓存处理包括在引用未命中时分配线路，以及当引用命中时从缓冲器/微型缓存器返回缓存数据。根据多个替换策略中的一个替换策略，在缓冲器/微型缓存中替换行，包括当没有可用的空行时停止替换。在正常模式下，当CPU开始在高功率状态下运行时，缓冲器/微型缓存类似于常规高速缓存，并且不能处理非缓存访问。在一种使用场景中，保留在缓冲/微型缓存中的数据是以压缩格式维护的图形刷新数据。

摘要： Small and power-efficient buffer/mini-cache sources and sinks selected DMA accesses directed to a memory space included in a coherency domain of a microprocessor when cached data in the microprocessor is inaccessible due to any or all of the microprocessor being in a low-power state not supporting snooping. Satisfying the selected DMA accesses via the buffer/mini-cache enables reduced power consumption by allowing the microprocessor (or portion thereof) to remain in the low-power state. The buffer/mini-cache may be operated (temporarily) incoherently with respect to the cached data in the microprocessor and flushed before deactivation to synchronize with the cached data when the microprocessor (or portion thereof) transitions to a high-power state that enables snooping. Alternatively the buffer/mini-cache may be operated in a manner (incrementally) coherent with the cached data. The microprocessor implements one or more processors having associated cache systems (such as various arrangements of first-, second-, and higher-level caches).
