摘要： A circuit and method to provide pipeline bit handling across a bus bridge between two different buses. In a preferred embodiment, the pipeline bit handling circuit provides rule enforcement for a P-bit address modifier across a bus bridge between two different buses with different rules for the P-bit address modifier. In a bus domain where pipeline transactions are allowed if the P-Bit is asserted and are not allowed if the P-Bit is not asserted, embodiments herein allow a master bus device to ensure that all bus devices will see a P=0 command with a defined minimum spacing to any other P=0 command. The required separation for P=0 commands is maintained within the bus bridge. In the preferred embodiments, the separation between P=0 commands is maintained by immediately retrying P=0 commands rather than spacing snoop requests.
摘要翻译：一种用于在两条不同总线之间的总线桥上提供流水线位处理的电路和方法。在优选实施例中，流水线位处理电路为P位地址修改器具有不同规则的两个不同总线之间的总线桥上的P位地址修改器提供规则强制。在一个总线域中，如果P位被断言，允许流水线事务被允许，并且如果P位不被置位则不允许流水线事务，这里的实施例允许主总线设备确保所有总线设备将看到P = 0命令，与任何其他P = 0命令的定义的最小间距。在总线桥内保持P = 0命令所需的间隔。在优选实施例中，通过立即重试P = 0命令而不是间隔窥探请求来保持P = 0命令之间的间隔。

摘要： A bus bridge for coupling between a first bus and a second bus includes: a number of data buffers for a particular request type; a counter for monitoring a number of requests of the particular type received at the bus bridge from the first bus for access to the second bus; and override logic. Each request of the particular type requires one data buffer of the number of data buffers for the particular request type. The override logic determines when the monitored number of requests of the particular type exceeds the number of data buffers for the particular request type at the bus bridge, and responsive thereto, initiates a request termination signal at the bus bridge to terminate a received request of the particular type. When request coherency is maintained employing snooping, the request termination signal is a retry snoop response signal output from the bus bridge.

摘要： A bus bridge for coupling between a first bus and a second includes: at least one data buffer; data load logic and data unload logic. The data load logic places received data in the at least one data buffer, wherein the data is received at the bus bridge from across the first bus in a first data ordering. The data unload logic automatically translates the received data from the first data ordering to a second data ordering during unloading of the data from the at least one data buffer for transfer across the second bus, wherein the first data ordering and the second data ordering are each a different one of a linear data ordering and an interleaved data ordering.

摘要： A bus bridge for coupling between a first bus and a second bus includes: multiple ticket registers; a ticket dispenser counter; and a ticket call counter. The ticket dispenser counter dispenses a ticket value to a request received at the bridge from the first bus for access to the second bus. This ticket value is held in one ticket register of the multiple ticket registers. The ticket call counter provides ticket call values, and the request is granted access to the second bus when a current ticket call value equals the ticket value dispensed to the request. While the request waits for access to the second bus, the bus bridge can perform work on the request. When request coherency is maintained employing snooping, ticket values assigned to a plurality of requests maintain a snoop response ordering of the requests for access to the second bus.

摘要： A field programmable gate array (FPGA) device including a non-programming-based default power-on electronic configuration. The non-programming-based default power-on electronic configuration defines a default state to initial a first logic function. Upon power-up, the FPGA device would be enabled to enter the default state without having first to be configured via a conventional programming mode, thus saving processing time during power-up. Several embodiments are disclosed, such as a mask via circuit, an asynchronous set/reset circuit, an unbalanced latch circuit and a flush and scan circuit. A related method is also disclosed to reduce the memory size dedicated to the first logic function to facilitate further programming after power-up. In addition to time saving and further programming, the FPGA device can also allow partial or incremental programming to expand the full functionality to match customer's different needs.
