6.16 Real-Time Interrupt Module
The real-time interrupt (RTI) module provides timer functionality for operating systems and for
benchmarking code. The RTI module can incorporate several counters that define the time bases needed
for scheduling an operating system.
The timers also let you benchmark certain areas of code by reading the values of the counters at the
beginning and the end of the desired code range and calculating the difference between the values.
6.16.1 Features
The RTI module has the following features:
• Two independent 64-bit counter blocks
• Four configurable compares for generating operating system ticks or DMA requests. Each event can
be driven by either counter block 0 or counter block 1.
• Fast enabling/disabling of events
• Two timestamp (capture) functions for system or peripheral interrupts, one for each counter block
6.16.2 Block Diagrams
Figure 6-11 shows a high-level block diagram for one of the two 64-bit counter blocks inside the RTI
module. Both the counter blocks are identical except the Network Time Unit (NTUx) inputs are only
available as time-base inputs for the counter block 0. Figure 6-12 shows the compare unit block diagram
of the RTI module.
