摘要： A first device is operable to communicate on an bus according to a first protocol. A bridge is also operable to communicate on the bus according to the first protocol. A second device is coupled to the bus via the bridge and operable to communicate according to a second protocol. The bridge has a memory for holding data received from the second device and is operable to translate from the second to the first protocol. The second device sends write data responsive to receiving a ready signal from the bridge, and includes memory for holding the write data that the second device has sent, but for which completion has not been signaled. The second device re-sends the write data from the memory responsive to receiving a non-completion signal via the bridge, and releases the memory for the data responsive to receiving a completion signal via the bridge.

摘要： A random number generator, a method, and a computer program product are provided for producing a random number seed. Each oscillator within an array of oscillators operates at a different frequency. The operating frequencies of each oscillator are not harmonically related, such that no integer multiple exists between the frequencies of any two oscillators. In one embodiment, the outputs of the array of oscillators connect to a multiple input latch. The multiple input latch also receives a sample signal, which is a clock signal. The clock signal samples the outputs of the array of oscillators, and the multiple input latch in conjunction with the random number determination logic (“RNDL”) produces a digital output (0 or 1) for each oscillator within the array. The RNDL uses these digital outputs to create a random number seed.

摘要： An approach to hiding memory latency in a multi-thread environment is presented. Branch Indirect and Set Link (BISL) and/or Branch Indirect and Set Link if External Data (BISLED) instructions are placed in thread code during compilation at instances that correspond to a prolonged instruction. A prolonged instruction is an instruction that instigates latency in a computer system, such as a DMA instruction. When a first thread encounters a BISL or a BISLED instruction, the first thread passes control to a second thread while the first thread's prolonged instruction executes. In turn, the computer system masks the latency of the first thread's prolonged instruction. The system can be optimized based on the memory latency by creating more threads and further dividing a register pool amongst the threads to further hide memory latency in operations that are highly memory bound.
摘要翻译： 介绍了一种在多线程环境中隐藏内存延迟的方法。 分支间接和设置链接（BISL）和/或分支间接和设置链接，如果外部数据（BISLED）指令在对应于延长的指令的实例的编译期间被放置在线程代码中。 延长的指令是指示计算机系统中的延迟，例如DMA指令。 当第一个线程遇到BISL或BISLED指令时，第一个线程在第一个线程的延长指令执行时将控制传递给第二个线程。 反过来，计算机系统掩盖了第一个线程延长的指令的延迟。 可以通过创建更多线程并在线程之间进一步划分寄存器池来进一步隐藏高度内存限制的操作中的内存延迟，从而可以基于内存延迟来优化系统。

摘要： A method and apparatus for adding and multiplying floating-point operands such that a fixed-size mantissa result is produced. In accordance with the present addition method, the mantissa of a first floating-point operand is shifted in accordance with relative operand exponent information. Next, the first operand mantissa is added to the second operand mantissa. The addition step includes replacing a least significant non-overlapped portion of the first operand mantissa with a randomly-generated carry-in bit. In accordance with the multiplication method, a partial product array is generated from a pair of floating-point operand mantissas. Next, prior to compressing the partial product array into a compressed mantissa result, a lower-order bit portion of the partial product array is replaced with a randomly generated carry-in value.

摘要： A system, method, and computer program product are provided for generating display data. The data processing system loads coefficient values corresponding to a behavior of a selected function in pre-defined ranges of input data. The data processing system then determines, responsive to items of input data, the range of input data in which the selected function is to be estimated. The data processing system then selects, through the use of a vector permute function, the coefficient values, and evaluates an index function at the each of the items of input data. It then estimates the value of the selected function through parallel mathematical operations on the items of input data, the selected coefficient values, and the values of the index function, and, responsive to the one or more values of the selected function, generates display data.
