GE IS200DSPXH2CAA Digital Signal Processor Control Board

IS200DSPXH2CAA Digital Signal Processor Control Board

The IS200DSPXH2CAA 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 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.

Features

· An inner loop load pulse signal captures the values of I/O such as bridge, motor, or generator voltages and current VCOs, tachometer counters, and discrete inputs. It can also synchronize the ISBus channels, the software, and gating outputs to bridges.

· At a sub-multiple or multiple of the inner loop load pulse, an application loop load pulse signal is used to capture values of other application VCOs and optionally the tachs.

· Stack overflow detection is provided for both the foreground stack (from internal memory) and the background stack (from external SRAM). Interrupt INT0 is generated if either stack overflows. If both stacks overflow, a hard reset is generated.

· A configuration register is provided to allow the stack overflow reset to be disabled. A watchdog timer is enabled and periodically toggled by the DSP (toggle interval is configurable). A time-out of the watchdog timer will generate a hard reset. A 24-bit free running timer is also provided and used as a reference for certain functions.

· Five differential (HIFI) pair application inputs may be used as two quadrature incremental tach interfaces (one with marker capability). The signals drive two 16- bit up/down counters. It maintains its present state when the inputs are at the same level, and changes state when the inputs are differentially opposite.

· A 5 MHz timer resets each time the counter increments or decrements, and a state register records the direction of the last count. Associated with each of these counters, timers, and registers is a capture register that can be configured to capture the values on the occurrence of either the inner loop load pulse or the application loop load pulse.

· The five differential HIFI inputs can be used as application layer VCO counters or single-channel tach interfaces. Five 16-bit counters increment on the differentially decoded and filtered inputs. These counter values are captured into registers the DSP can read by the application loop load pulse.

· Six inputs from the backplane are digitally filtered and input to the VCO counters. These are 16-bit counters with capture registers latched by the inner loop load pulse and readable by the DSP. The inputs come from technology-specific I/O cards such as BIC (bridge interface) or exciter interface cards.
