2367 FASTCAMAC Compatible Universal Logic Module

 

 

User Programmable Logic and Processer Module with 3 MByte RAM

The CAMAC Model 2367 is a versatile general purpose programmable logic module employing a Xilinx 4013E Field  Programmable Gate Array (FPGA), Texas Instruments TMS320F206S Digital Signal Processer (DSP), and 3 MByte RAM. With the 2367, CAMAC users have the ablility to solve a wide variety of Logic/Processing problems, all with a single module.  It contains 59 front panel I/O lines, programmable as inputs or outputs, that are mapped to the user-programmable Xilinx FPGA, as well as three on board clocks at the user's disposal.

In addition to the ability to perform simple logic functions as well as elaborate arithmetic calculations, the RAM, FPGA, and  DSP give the user the power to operate the 2367 in ways unavailable to the 2366 logic Module, e.g. as a histogramming memory module. The module also contains 64 kBytes of non-volatile memory internal to the DSP chip (principally for DSP program storage) and an on-board 64 kBytes of non-volatile EEPROM memory for FPGA program retention. Virtually no digital application is out of its range.

FUNCTIONAL DESCRIPTION

The desired logic operations are programmed in a Xilinx 4013E gate array chip. Any logic that can be implemented as a synchronous (clocked) state machine may be programmed, subject only to the size limitation of the Xilinx gate array of approximately 13,000 equivalent gates. There are 3 clocks available on-board (40, 20, and 10 MHz), and any of 3 special front panel inputs may also be used as clocks. Input and output signals use standard 10124 and 10125 TTL-ECL level translators. Input signals as short as 5 nanoseconds can be latched and synchronized with the internal state machine logic.

The FPGA can receive its configuration from either the EEPROM, or via a Xilinx .bit file uploaded via CAMAC commands.  The EEPROM can hold two separate programs, and   may be reprogrammed at any time, allowing the user to upload their own custom application.  The FPGA is will automatically receive its configuration from the EEPROM upon power-up.

The 2367 is shipped with a EEPROM that holds the following configurations:

CAMAC Dataway & Memory Tester

With this configuration, the 2367 behaves as a CAMAC Dataway tester,  and as million word memory. The DSP execution of a user program loaded in RAM can be started and stopped. This configuration is available on power-up, as long as the EEPROM is not overwritten.

FERA List Memory

With this configuration, the 2367 behaves similar to a LeCroy Model 4302 FERA Memory, with a depth of 512k addresses X 16 bit. The front panel is designed to receive the FERA WRITE STOBE and to return an ACKNOWLEDGE signal.  Overflow and Full outputs are also available.
