DS200DSPCH1ADA GE LCI Digital Signal Processor Control board

Description:

The DS200DSPC board (DSPC) is a high performance processor board based on a digital signal processor that provides computational capacity and communications bandwidth for direct control of high performance power converter applications such as uninterruptable power sources (UPS), active filters, dynamometers, wind turbines, high performance drives, and large multi-bridge power converters. The board plugs into one slot of a VME rack, but occupies two slots of space (for quantity of one to four daughterboards). The DSPC board can serve as a master or slave device, yet it provides its own program memory and expandable local high speed I/O for direct interface to control signals without using the VME datapath.

Features:

The DSPC board processor is a floating point digital signal processor (DSP) that operates at 50 MHz. The DSP can be reset by one of the following methods:
·  VME sysreset
·  VME master bus writes to the VME control register
·  Power-up reset
·  Reset pushbutton
A watchdog timer with timeout fixed at 1ms monitors the DSP.

VME Bus
The DSPC board provides optional VME bus interface connectors (P1 and P2) that are compatable with the GE Fanuc 90/70ä Programmable Logic Controllers (PLCs). The DSPC board can function as an A24/D16 VME bus slave with a 8K dual-ported SRAM interface. The board can also function as a VME bus master to initiate a bus transfer cycle, including bus arbitration. VME bus access is controlled in a configurable static random access memory (SRAM) based field programmable gate array (FPGA) device. Bus interface configuration information resides in a programmable logic device that can be reconfigured as required for a specific application (this method minimizes manual jumpers). VME bus I/O is asynchronous and a timeout is provided for nonresponding addresses.

Daughterboard Options
The DSPC board has provisions for mounting up to four optional daughterboards for communication and I/O expansion. A pair of high density connectors, one 60-pin (XA1, 2, 3, 4) and one 40-pin (XB1, 2, 3, 4), provide mounting and signal connection to each of the four daughterboard positions. Additional mounting rigidity is provided by three standoffs (with screws) per daughterboard position on the DSPC board. The daughterboards do not engage the VME rack guides. The four daughterboard positions are interchangable (any daughterboard can be assigned per project to any of the four positions). The positions are not interchangable after being project-assigned.

The DSPC board provides input and output signal lines for synchronization and interrupt requirements. Configuration lines for each daughterboard position are supplied to allow parallel downloading of FPGA logic. A status line from each position allows the DSP to monitor the daughterboard for successful configuration completion.
