GE IS200DSPXH1DBD Digital Signal Processor Control Card
Description:
IS200DSPXH1DBD is part of GE EX21000 excitation control series card. IS200DSPXH1DBD is a digital signal processor control board.
The IS200DSPX Digital Signal Processor Control Board (DSPX) is the primary controller for the bridge and motor regulator and gating functions for Innovation Series drives. It also controls generator field control functions for the EX2100 Excitation Control. The board provides logic, processing, and interface functions. The DSPX board includes a high performance digital signal processor (DSP), standard memory components, and an application specific integrated circuit (ASIC) that performs custom logic functions.
The DSPX’s Digital Signal Processor (DSP) runs at 60 MHz. Four externalinterrupts to the DSP are provided during normal operation:
Stack overflow (INT0)
Inner loop load pulse (INT1)
Two configurable inputs (INT2, INT3)The following types of memory are provided on the DSPX board:
FLASH memory for DSP boot images, code execution, and configurable itemstorage, along with system history records
RAM for data storage and code execution
NVRAM for nonvolatile data storage
Add-only memory for board revision identification
Specialized functions of the DSPX board are provided through custom logic in Field Programmable Gate Arrays (FPGA) or ASICs with supporting circuits as required. Most specialized and support functions are contained in a single ASIC.
