摘要： Serial communication circuitry (10) having multiple queues (11-14) for use in a data processing system (95). Each queue (11-14) has multiple entries (52). Serial transfers from the multiple queues (11-14) are carried out under the control of global parameters (e.g. 205, 209), per-queue parameters (e.g. 211-212, 214-217), and per-entry parameters (e.g. 350-361). Each queue can be programmed to have a different set of per-queue parameters, and each entry within a queue can be programmed to have a different set of per-entry parameters. In addition, serial communication circuitry (10) can perform serial data transfers in response to the assertion of a trigger signal (30) from a source such as a timer (63) or a central processing unit (61). As a result, data transfers can be more precisely related to a particular timing signal or set of timing signals.

摘要： A digital timer apparatus incorporates a free running counter, an interval timer, a capture register, a pulse accumulator and holding logic. A rising or falling edge of an external signal causes the current contents of the free running counter to be loaded into the capture register and causes the pulse accumulator to be incremented. The output of the interval timer can cause the contents of the pulse accumulator and capture register to be stored into the holding logic. The timer apparatus is particularly well suited to performing tasks related to the determination of the speed of rotation of a rotating member and may be used, for instance, in detecting wheel rotational speeds in an anti-lock brake system or detecting shaft rotation speeds in an automatic transmission.

摘要： Timebase channels in different I/O control modules (IOCMs 281-284 in FIG. 16) or on different integrated circuits (300-302 in FIG. 17 ) may provide synchronized, coherent timebase values to different blocks of work and other channels (e.g. 86 in FIG. 2) that are coupled to different timer buses (e.g. 71 in FIG. 2). In one embodiment, referring to FIGS. 1-19, two or more timebase channels, e.g. master timebase channel (285) and slave timebase channel (288), can be synchronized and kept in synchronization using just two signals, namely a clock signal (328) and a synchronization signal (329). The master timebase channel (285) generates or receives a master dock signal (328) which is coupled to one or more slave timebase channels (288) to ensure that the master and slave timebase channels (285, 288) increment or decrement at the same time and rate.
