1.5. FPGA
The FPGA is to be configured over Comm-Port 3 via the CPLD. The configuration bitstream
is sent by a ‘C6x or ‘C4x processor. This feature will allow a system to dynamically change
the FPGA firmware. The configuration LED indicates that configuration is complete.
The FPGA drives 4 LEDs, and is connected to it’s own local oscillator package.
The FPGA firmware will be user defined, and can be done on demand.
Typical functions that can be implemented in the FPGA are:
• Full bi-directional global-bus interface
• Full bi-directional Comm-Port interface
• Bi-directional SDB Interface
• RAM, FIFOs, Dual port RAMs up to a total of 16K Bytes
• Communication protocols
• DSP pre-processors
• Any digital function that will fit in this size device
The SMT338 TIM can typically be used to interface with a SMT338 Frame Grabber over the
SDB connectors. The SMT338 can then perform customer specific data formatting before
sending it to a nearby C40 TIM via Comm-Port.
Due to the parallel nature of an FPGA it is well suited to handle multiple high-speed I/O lines.
The FPGA can then provide a cleaner bus-interface to the associated DSP processors.
2. Installation
The minimum system requirements needed to run a SMT338 on a PC is a C4x TIM-
based carrier board and a C4x or C6x TIM with at least a Transmit Comm-Port
(Comm-Port 0,1 or 2) at Reset.
The goal is to connect one of the processors Comm-Port to Comm-Port 3 of the
SMT338.
Follow these steps to install the SMT338 module on a Host system:
1. Remove the carrier board from the host system.
2. Place the SMT338 module into one of the TIM sites on the carrier board.
