摘要： An apparatus and method for simulating a multi-ported memory using lower port count memories as banks. A collector units gather source operands from the banks as needed to process program instructions. The collector units also gather constants that are used as operands. When all of the source operands needed to process a program instruction have been gathered, a collector unit outputs the source operands to an execution unit while avoiding writeback conflicts to registers specified by the program instruction that may be accessed by other execution units.

摘要： A memory is used by concurrent threads in a multithreaded processor. Any addressable storage location is accessible by any of the concurrent threads, but only one location at a time is accessible. The memory is coupled to parallel processing engines that generate a group of parallel memory access requests, each specifying a target address that might be the same or different for different requests. Serialization logic selects one of the target addresses and determines which of the requests specify the selected target address. All such requests are allowed to proceed in parallel, while other requests are deferred. Deferred requests may be regenerated and processed through the serialization logic so that a group of requests can be satisfied by accessing each different target address in the group exactly once.

摘要： A shared memory is usable by concurrent threads in a multithreaded processor, with any addressable storage location in the shared memory being readable and writeable by any of the threads. Processing engines that execute the threads are coupled to the shared memory via an interconnect that transfers data in only one direction (e.g., from the shared memory to the processing engines); the same interconnect supports both read and write operations. The interconnect advantageously supports multiple parallel read or write operations.

摘要： A scoreboard memory for a processing unit has separate memory regions allocated to each of the multiple threads to be processed. For each thread, the scoreboard memory stores register identifiers of registers that have pending writes. When an instruction is added to an instruction buffer, the register identifiers of the registers specified in the instruction are compared with the register identifiers stored in the scoreboard memory for that instruction's thread, and a multi-bit value representing the comparison result is generated. The multi-bit value is stored with the instruction in the instruction buffer and may be updated as instructions belonging to the same thread complete their execution. Before the instruction is issued for execution, this multi-bit value is checked. If this multi-bit value indicates that none of the registers specified in the instruction have pending writes, the instruction is allowed to issue for execution.
摘要翻译：用于处理单元的记分板存储器具有分配给要处理的多个线程中的每一个的分离的存储器区域。对于每个线程，记分板存储器存储具有待处理写入的寄存器的寄存器标识符。当指令被添加到指令缓冲器中时，将指令中指定的寄存器的寄存器标识符与存储在该指令的线程的记分板存储器中的寄存器标识进行比较，并生成表示比较结果的多位值。多位值与指令一起存储在指令缓冲器中，并且可以更新为属于同一线程的指令完成其执行。在执行指令之前，将检查该多位值。如果该多位值表示指令中没有指定的寄存器没有挂起写操作，则允许指令执行。
