摘要： A dual access debugging architecture. This architecture allows the microprocessor to select between external debugging, supported via the physical system interface, and internal debugging, supported via logic within the microprocessor which is controlled by decoded software instructions. In one example of the present invention, a microprocessor includes a system bus interface and a program decoder which is coupled to the system bus interface. The system bus interface is coupled to a system bus to which external memory is coupled. Debugging operations are stored as debugging instructions in the external memory. When these debugging instructions are retrieved from memory, through the system bus and the system bus interface, they are decoded in the program decoder of the microprocessor and they in turn cause the microprocessor to enter a first debugging mode which is controlled by the debugging instructions. The first debugging mode may be referred to as an internal programmable method. The microprocessor also includes a dedicated test port, such as a JTAG port, which provides signals to and from registers and other logic in test port logic on the IC (integrated circuit) of the microprocessor. The dedicated test port includes input/output pins on the microprocessor which convey the test signals to external test logic device, such as JTAG test equipment. Testing of the microprocessor using the dedicated test port involves asserting a signal in the test port which causes the microprocessor to enter a second debugging mode which is controlled by the external test logic device. This second debugging mode may be referred to as an external debug method.
摘要翻译：双重访问调试架构。该架构允许微处理器通过物理系统接口支持的外部调试和通过由解码的软件指令控制的微处理器内的逻辑支持的内部调试进行选择。在本发明的一个示例中，微处理器包括系统总线接口和与系统总线接口耦合的程序解码器。系统总线接口耦合到外部存储器耦合到的系统总线。调试操作作为调试指令存储在外部存储器中。当这些调试指令从存储器，通过系统总线和系统总线接口获取时，它们被解码在微处理器的程序解码器中，并且进而导致微处理器进入由调试指令控制的第一调试模式。第一调试模式可以被称为内部可编程方法。微处理器还包括专用测试端口，例如JTAG端口，它向微处理器的IC（集成电路）的测试端口逻辑中的寄存器和其他逻辑提供信号。专用测试端口包括微处理器上的输入/输出引脚，将测试信号传送到外部测试逻辑器件，如JTAG测试设备。使用专用测试端口对微处理器的测试涉及在测试端口中断定信号，使得微处理器进入由外部测试逻辑器件控制的第二调试模式。该第二调试模式可以被称为外部调试方法。

摘要： A method and an apparatus using, in one embodiment, a multiple split mode for issuing multiple read or write requests that may be used during a data transaction within a computer system. In one embodiment, a processing unit comprises a bus arbitrator having bus control lines for controlling a bus, which transmits address and data information. The arbitrator is capable of issuing multiple consecutive read or write requests including at least one read request on the bus without releasing control by the processing unit over the bus during the consecutive read or write requests. In addition, the arbitrator is also designed to abort consecutive read requests during address cycles in response to bus control lines.

摘要： A reversible connector and method of connection between a large road making machine and the fifth wheel of a tractor to facilitate towing of the machine. The connector has a downwardly projecting king pin which is adjustable between a retracted, operating position and an extended, towing position. It can be either slid or pivoted between those positions. The connector can be used on an apparatus having a chassis, a downwardly extending conveyor pivotally attached to an end of the chassis and a hydraulic cylinder to pivot the conveyor relative to the chassis. The hydraulic cylinder can lift the inlet end of the conveyor off the ground to put the fifth wheel connector in a position such that it can engage the fifth wheel of a tractor. The hydraulic cylinder also can be used to pull the front portion of the chasis up off the ground.
