摘要： Data streams are generated for tracing target processor activity. When multiple streams are on, they are written at different times into their individual FIFO. It is possible that for a specific stream, the length and fields of the data that should be exported vary. This invention is a scheme to send out only the relevant fields.
摘要翻译：生成跟踪目标处理器活动的数据流。当多个流打开时，它们会在不同的时间被写入其各自的FIFO。对于特定的流，可能导出的数据的长度和字段可能不同。本发明是仅发出相关领域的方案。

摘要： A method of tracing program counter activity in a data processor periodically transmits a program counter sync point including the current program counter address. Between sync points the program counter address is indicated by a program counter offset relative to the last program counter sync point. The program counter offset is sent as integral number of sections of a predetermined number of bits. Program counter sync points are transmitted often enough so that the program counter offset requires at most one less section than the program counter address.

摘要： A method of tracing data processor activity with recover from detection of trace stream corruption. If the first trace data following detection of corruption is not a program counter sync point, then the trace transmits an indication of the current program counter address in an offset format from the program counter address of a last transmitted program counter sync point and then transmits trace data in event offset format. If the first trace data following detection of corruption is a program counter sync point, then the trace transmits trace data in event offset format.

摘要： A method of trace data compression receives trace data on a first port and a second port stores a prior data value. If trace data is received on only one port, then that trace data is transmitted as an indication of matching and non-matching sections between the current trace data and the stored data value and the non-matching sections of the current trace data on the one port. If trace data is received on both ports, then the first port trace data is transmitted relative to the prior stored value and the second port trace data is transmitted relative to the first port trace data. The stored prior data is reset to zero upon each initiation or termination of trace data on either port. The stored prior value is set to the second port value or the first port value if no second port value is received.
摘要翻译：跟踪数据压缩的方法在第一端口上接收跟踪数据，而第二端口存储先前的数据值。如果仅在一个端口上接收到跟踪数据，则该跟踪数据作为当前跟踪数据与存储的数据值之间的匹配和非匹配部分的指示以及当前跟踪数据的不匹配部分在一个端口上发送港口。如果在两个端口上都接收到跟踪数据，则相对于先前存储的值传输第一个端口跟踪数据，并且相对于第一个端口跟踪数据传输第二个端口跟踪数据。在任一端口上的跟踪数据的每次启动或终止时，存储的先前数据被重置为零。如果没有接收到第二个端口值，则将存储的先前值设置为第二个端口值或第一个端口值。

摘要： A method of scheduling trace packets in an integrated circuit generating trace packets of plural types stores trace data in respective first-in-first-out buffers. If a timing trace data first-in-first-out buffer is empty, timing trace data packet is transmitted. If a program counter overall data first-in-first-out buffer is not empty and the processor is at a data interruptible boundary, transmitting a program counter data packet. If data first-in-first-out buffer is not empty, transmitting a data packet. The program counter data packets include program counter sync data, program counter exception data, program counter relative branch data and program counter absolute branch data.

摘要： A method of preventing trace data first-in-first-out buffer overflow in a pipelined data processor stops new instructions when a trace data first-in-first-out buffer is in danger of overflowing. The method also stalls a predetermined number of pipeline stages in the pipeline ahead of the first pipeline stage. The trace data first-in-first-out buffer is emptied while the pipeline is stalled. On restart, the stalled pipeline stages are restarted ahead of re-enabling new instructions. Asynchronous trigger events received during the stall may be buffered and unrolled in order or merely stored and applied simultaneously on restart.
摘要翻译：一种在流水线数据处理器中防止跟踪数据先进先出缓冲区溢出的方法在跟踪数据先进先出缓冲区处于溢出危险时停止新指令。该方法还在第一流水线阶段之前的流水线中停止预定数量的流水线级。当管道停滞时，跟踪数据先进先出缓冲区被清空。重新启动后，在重新启用新指令之前重新启动停滞的流水线阶段。在停止期间接收的异步触发事件可以按顺序缓冲和展开，或者仅在重新启动时同时存储和应用。

摘要： During a trace the timing stream has the active and stall information, PC stream has all the discontinuity information, and the data stream has all the data log information. The various streams are synchronized using markers called sync points. The sync points provide a unique identifier field and a context to the data that will follow it. After data corruption a sync point is inserted into the data stream. The ID of this sync point may repeat a previous sync point ID.

摘要： This invention provides trace address compression by comparing respective bytes of a current trace address with a stored comparison address. Only the least significant bytes of the current trace address that do not match the comparison address or are less significant than any section of the current trace address that does not match the comparison address are transmitted. This sometimes reduces the amount of data that needs to be transmitted. The comparison address is specified by a central processing unit via a memory mapped register write operation.
