2.4. HTM trace generation blocks
The trace generation blocks include:
- Sampling registers for AHB signals
The sampling logic registers all the signals from
the traced AHB.
- Packet generator
The packet generator filters the AHB transfer based on the TraceEnable signal from the Comparators
and Resources Block, and then packs the AHB transfer information
into an address packet, auxiliary packet, and data packet. Data
suppression is also done here.
- FIFO
The FIFO controller
monitors the space remaining in the FIFO and controls the shift
in and shift out of data.
- ATB interface
The
ATB interface outputs the trace packets, and interfaces with the
FIFO for ATB flush functions.
