Field Programmable Gate Arrays
The TMS and the modules that plug into it, contain Field Programmable Gate Arrays (FPGAs). The
software that configures the FPGA is called an image.
FPGA and the Boot ROM
FPGAs are dynamic devices and do not retain their image definition when power is removed. The
image definition for each device is loaded from an image definition file (*.idf) during the system boot
sequence. The TMS contains a boot ROM that statically stores the names of the .idf files for the
devices on its motherboard and the modules that are plugged in.
When a new system is installed, when an existing system has components added or replaced, or
when the system is upgraded, the boot ROM must be verified. See
ROM Settings on page 139.
Local Resources (DSPs)
The TMS motherboard contains DSPs programmed to make resources available. Examples of TMS-
supported resources are:
• Player (ply) - Vocabularies or audio data can be played from local memory on the TMS
motherboard.
• DTMF Receiver (dtmf) and Call Progress Detection (cpd) - Phone line events such as
touchtone entry, hook-flash, dial tone, busy signals, and so on can be detected.
• Tone Generator (tgen) - In lieu of playing tones as vocabularies, DTMF and other tones can be
generated.
• R1 Transmit (r1tx), R1 Receive (r1rx), and R2 (r2) - Tone generators and detectors that
support R1 and R2 protocols.
If the resident DSPs are fully allocated to resources or protocols, capacity for more resources can
be added by installing a MDM in an open TMS slot and loading the image definitions for the
resources required.
Multiple DSP Module
The Multiple DSP Module (MDM) contains twelve DSPs for configuring additional resources. There
are no indicators or connectors on the front panel of the MDM. The only visible indication that an
MDM is installed in a TMS slot (versus a blank), is bend tabs near the center of the front bracket that
secure it to the MDM circuit board.
