英汉例句

• It turns out that several SPU instructions deal with only one of the register「s values.

  几个SPU指令只能处理这些寄存器值中的一个。

• The SPU has a read channel for receiving a single data word from the mailbox and two write channels for sending data words (more on this below).

  SPU有一个读通道来从邮箱接收单个数据字，有两个写通道来发送数据字(更详细的介绍请参看下文)。

• While it would be relatively easy to create a new GDB target for the SPU itself, most users need to debug interaction between PPE and SPE.

  虽然为SPU自己创建一个新的GDB目标非常简单，但是大部分用户都需要对PPE和SPE之间的交互进行调试。

• If a serious error occurs, for example, an invalid opcode, the SPU is stopped and an interrupt is delivered to the ppe.

  如果发生了一个非常严重的错误，例如一个无效的操作码，那么SPU就会停止，并向PPE发送一个中断。

• The SPU actually loads two instructions at a time from a doubleword-aligned boundary.

  SPU实际上会从一个双字对齐的边界开始一次加载两条指令。

• This requires changes to the OProfile kernel code to sample the SPU instruction Pointers regularly.

  这需要修改oprofile的内核代码来周期性地对SPU指令指针进行采样。

• In addition, by default, every branch encountered by the SPU is assumed to be not taken, including unconditional branches.

  另外，默认情况下，SPU所碰到的每个分支都应当不会执行，包括无条件分支。

• Branch hinting is necessary on the SPU because mispredicted branches come at a high cost.

  分支提示之所以在SPU是必需的是因为预测错误的分支可能会带来高耗费。

• In the future, we are planning to change this so that more logical than physical SPU contexts can be present and have the kernel switch between them.

  将来，我们计划要对此进行修改，使其可以保存逻辑上下文而不只是物理spu上下文，并且可以采用一些内核开关来切换它们。

• Most importantly, if each SPU is represented by a single character device, it becomes hard for an application to find an SPU that is not yet used by another.

  最为重要的是，如果每个SPU都是由一个字符设备来表示的，那么程序就很难发现一个还没有被其他程序使用的SPU。

• Here are some of the more common SPU intrinsics (types are not given as most of them are polymorphic).

  下面是比较常见的一些SPUintrinsic(类型没有给出，这是因为它们大多为多态)。

• A single process can work with multiple SPU contexts, but to run on more than one SPU at a given time, the process needs to contain at least one thread for each running SPU context.

  一个进程可以使用多个spu上下文，但是要在每个给定的时间点上在多个SPU上运行，这个进程需要包含至少一个每个正在运行的SPU上下文所使用的线程。

• SPU code is compiled separately from the PPC code and gets loaded at run time.

  SPU代码与PPC代码分开进行编译，并在运行时进行加载。

• Only the kernel can directly communicate with an SPU and therefore needs to abstract the hardware interface into system calls or device drivers.

  只有内核才可以直接与SPU进行通信，因此需要将硬件接口抽象为系统调用或设备驱动程序。

• mbox and ibox are used to read data written to the SPU mailbox write channels and have slightly different semantics.

  mbox和ibox用来读取那些被写入SPU邮箱写通道的数据，不过语义稍有不同。

• Topics covered include the basic architecture, the syntax of the SPU assembly language, and the primary modes of communication between the SPE and the PPE.

  所讨论的主题包括基本的架构、SPU汇编语言的基本语法及SPE与ppe间的主要通信模式。

• The only byte-oriented arithmetic function on the SPU is absdb, 「absolute difference of bytes,」 which gives the absolute value of the difference between two operands.

  SPU 上惟一一个面向字节的计算函数是absdb（意思是 「absolutedifferenceofbytes」），计算两个操作数间的差的绝对值。

• A signal might need to be delivered to a thread that is executing SPU code.

  我们可能需要将信号发送给正在执行SPU代码的线程。

• Since the SPU has 128 registers, it can keep a lot of temporary and intermediate values around without having to load and store back into memory like other architectures.

  由于SPU有128个寄存器，所以它可以存储大量临时值和中间值，而无需像其他架构一样，必须加载和向内存转存。

• The two transmission steps do not involve the SPU at all, but only the MFC (which is part of the larger SPE).

  两个传输步骤根本没有涉及SPU，只涉及MFC(这是比较大的SPE的一部分)。

• A private memory area within the SPU called the local store (the size of this area on the PS3 is 256k).

  SPU中的一个私有内存区域，称为本地存储(PS 3上这个区域的大小是256k)。

• The SPU has no real hardware support for branch hinting.

  SPU对于分支提示并没有没有实际硬件支持。

• This is critical, as the SPU can only load exactly 16 bytes at a time, aligned to exactly a 16-byte boundary.

  这十分关键，因为SPU一次只能加载16字节，并对齐到16字节的边界。

• When an SPU tries to read from an empty mailbox, it will stop execution until some value is written to its memory-mapped register.

  当spu视图从一个空的邮箱中读取信息时，它会停止执行，直到有值写入自己的内存映射寄存器中为止。

• Look at one iteration in the loop and see how it performs in the SPU pipeline. I」ve added no-ops so you can see the pipeline issues better.

  下面让我们查看这个循环中的一次迭代，并了解一下它在SPU流水线中是如何执行的。
