| 发明名称 | Multi-processor synchronization using time base counters | ||
| 摘要 | A multi-processor system includes a first processor that includes a first time base counter that outputs a first time base count, a second processor that includes a second time base counter that outputs a second time base count, and a communication bus. The first and second processors exchange the first and second time base counts on the communication bus. The first and second processors determine a skew based upon a difference between the first and second time base counts, and the first and second processors synchronize with each other based upon the skew. | ||

| 主权项 | 1. A multi-processor system comprising: a first processor that includes a first time base counter that outputs a first time base count; a second processor that includes a second time base counter that outputs a second time base count; a communication bus, wherein the first and second processors exchange the first and second time base counts on the communication bus; wherein the first and second processors determine a skew based upon a present difference between the first and second time base counts; wherein the first and second processors synchronize with each other based upon the skew; wherein the first and second processors exchange the first and second time base counts during initialization to determine an initial difference between the first and second time base counts; and wherein the skew is further based upon a difference between the present difference and the initial difference. | ||
