    • In a computer system supporting memory compression and wherein data is stored on a disk in a different compressed format, and wherein an IOA (input/output adaptor)/IOP (input/output processor) selectively reads from and writes to a main memory through a direct memory access (DMA) operation, a method for transmitting compressed data from the IOA/IOP to the main memory includes reserving a set of free memory sectors to contain the data in said main memory, sending to the IOA/IOP addresses of said memory sectors, copying the data from the IOA/IOP to said memory sectors using said DMA operation, constructing at the IOA/IOP compressed memory directory information defining how and where the data is stored in memory, sending the memory directory information to a memory controller, and storing the memory directory information in the compressed memory directory structure.

    • A computer system and corresponding method for supporting a compressed main memory includes a processor, a processor cache in signal communication with the processor, a memory controller in signal communication with the processor cache, a compression translation table entry register in signal communication with the processor cache and the memory controller, a compression translation table directory in signal communication with the compression translation table entry register, and a compressed main memory in signal communication with the memory controller wherein the memory controller manages the compressed main memory by storing entries of the compression translation table directory into the processor cache from the compression translation table entry register; where the corresponding method includes receiving a real address for a processor cache miss, finding a compression translation table address for the cache miss within the processor cache, if the cache miss is a cache write miss: decompressing the memory line corresponding to the cache line being written, writing the content of the cache line into the appropriate position in the memory line, compressing the data contained in said memory line, and storing the compressed data into the compressed main memory, and, if the cache miss is a cache read miss: retrieving the compressed data corresponding to the compression translation table address from the compressed main memory and decompressing the retrieved data.
    • 用于支持压缩主存储器的计算机系统和相应方法包括处理器,与处理器进行信号通信的处理器高速缓存器,与处理器高速缓存器进行信号通信的存储器控​​制器,与处理器高速缓存器进行信号通信的压缩转换表输入寄存器 和存储器控制器,与压缩转换表入口寄存器进行信号通信的压缩转换表目录以及与存储器控制器进行信号通信的压缩主存储器,其中存储器控制器通过存储压缩转换表的条目来管理压缩主存储器 目录进入处理器缓存从压缩转换表入口寄存器; 其中相应的方法包括接收处理器高速缓存未命中的实际地址,如果高速缓存未命中是高速缓存写入未命中,则为处理器高速缓存中的高速缓存未命中找到压缩转换表地址;解压缩对应于高速缓存行的存储器行为 写入,将高速缓存行的内容写入存储器线中的适当位置,压缩所述存储器线中包含的数据,并将压缩数据存储到压缩主存储器中,并且如果高速缓存未命中是高速缓存读取缺失: 从压缩的主存储器中检索与压缩转换表地址相对应的压缩数据,并解压缩检索的数据。
