摘要： A method and apparatus for ensuring fair and efficient use of a shared memory buffer. A preferred embodiment comprises a shared memory buffer in a multi-processor computer system. Memory requests from a local processor are delivered to a local memory controller by a cache control unit and memory requests from other processors are delivered to the memory controller by an interprocessor router. The memory controller allocates the memory requests in a shared buffer using a credit-based allocation scheme. The cache control unit and the interprocessor router are each assigned a number of credits. Each must pay a credit to the memory controller when a request is allocated to the shared buffer. If the number of filled spaces in the shared buffer is below a threshold, the buffer immediately returns the credits to the source from which the credit and memory request arrived. If the number of filled spaces in the shared buffer is above a threshold, the buffer holds the credits and returns the credits in a round-robin manner only when a space in the shared buffer becomes free. The number of credits assigned to each source is sufficient to enable each source to deliver an uninterrupted burst of memory requests to the buffer without having to wait for credits to return from the buffer. The threshold is the point when the number of free spaces available in the buffer is equal to the total number of credits assigned to the cache control unit and the interprocessor router.
摘要翻译：一种用于确保公平和有效地使用共享存储器缓冲器的方法和装置。优选实施例包括在多处理器计算机系统中的共享存储器缓冲器。来自本地处理器的存储器请求由高速缓存控制单元传送到本地存储器控制器，并且来自其他处理器的存储器请求由处理器间路由器递送到存储器控制器。存储器控制器使用基于信用的分配方案在共享缓冲器中分配存储器请求。高速缓存控制单元和处理器间路由器分配有多个信用。当请求分配给共享缓冲区时，每个都必须向内存控制器支付抵免额。如果共享缓冲区中的填充空间数量低于阈值，则缓冲区立即将信用返回到信用和存储器请求到达的来源。如果共享缓冲器中的填充空间数目高于阈值，则缓冲器只有当共享缓冲器中的空间变得空闲时才保存信用并以循环方式返回信用。分配给每个源的信用点数量足以使每个源能够将不间断的存储器请求发送到缓冲器，而不必等待信用从缓冲器返回。阈值是缓冲器中可用空间的数量等于分配给缓存控制单元和处理器间路由器的总信用数量的点。

摘要： A method and architecture for improved system resource management and allocation for the processing of request and response messages in a computer system. The resource management scheme provides for dynamically sharing system resources, such as data buffers, between request and response messages or transactions. In particular, instead of simply dedicating a portion of the system resources to requests and the remaining portion to responses, a minimum amount of resources are reserved for responses and a minimum amount for requests, while the remaining resources are dynamically shared between both types of messages. The method and architecture of the present invention allows for more efficient use of system resources, while avoiding deadlock conditions and ensuring a minimum service rate for requests.

摘要： A network transport layer accelerator accelerates processing of packets so that packets can be forwarded at wire-speed. To accelerate processing of packets, the accelerator performs pre-processing on a network transport layer header encapsulated in a packet for a connection and performs in-line network transport layer checksum insertion prior to transmitting a packet. A timer unit in the accelerator schedules processing of the received packets. The accelerator also includes a free pool allocator which manages buffers for storing the received packets and a packet order unit which synchronizes processing of received packets for a same connection.

摘要： A system and method is disclosed to track a large number of open pages in a computer memory system. The computer system contains one or more processors each including a memory controller containing a page table, the page table organized into a plurality of rows with each row able to store an address of an open memory page. A RIMM module containing RDRAM devices is coupled to each processor, each RDRAM containing a plurality of memory banks. The page table increases system memory performance by tracking a large number of open memory pages. Associated with the page table is a bank active table that indicates the memory banks in each RDRAM device having open memory pages. The page table enqueues accesses to the RIMM module in a precharge queue resulting from a page miss caused by the address of an open memory page occupying the same row of the page table as the address of the system memory access resulting in the page miss. The page table also enqueues accesses to system memory in a Row-address-select (“RAS”) queue resulting from a page miss caused by a row of the page table not containing any open memory page address. The page table enqueues accesses to system memory resulting in page hits to open memory pages in a Column-address-select (“CAS”) queue. An entry in the precharge queue is then enqueued into the RAS queue. An entry in the RAS queue after completion is enqueued into the CAS Read or CAS Write queue.

摘要： A system and method is disclosed that reduces the latency of directory updates in a directory based Distributed Shared Memory computer system by speculating the next directory state. The distributed multiprocessing computer system contains a number of processor nodes each connected to main memory. Each main memory may store data that is shared between the processor nodes. A Home processor node for a memory block includes the original data block and a coherence directory for the data block in its main memory. An Owner processor node includes a copy of the original data block in its associated main memory, the copy of the data block residing exclusively in the main memory of the Owner processor node. A Requestor processor node may encounter a read or write miss of the original data block and request the data block from the Home processor node. The Home processor node receives the request for the data block from the Requestor processor node, forwards the request to the Owner processor node for the data block and performs a speculative write of the next directory state to the coherence directory for the data block without waiting for the Owner processor node to respond to the request.

摘要： A computer system includes a memory controller interfacing the processor to a memory system. The memory controller supports a memory system with a plurality of memory devices, with multiple memory banks in each memory device. The memory controller supports simultaneous memory accesses to different memory banks. Memory bank conflicts are avoided by examining each transaction before it is loaded in the memory transaction queue. On a first clock cycle, the new pending memory request is transferred from a pending request queue to a memory mapper. On the subsequent clock cycle, the memory mapper formats the pending memory request into separate signals identifying the DEVICE, BANK, ROW and COLUMN to be accessed by the pending transaction. In the next clock cycle, the DEVICE and BANK signals are compared with every entry in the memory transaction queue to determine if a bank conflict exists. If so, the new memory request is rejected and recycled to the pending request queue.
