IXD7232 Curtiss-Wright Real-Time Signal Processing VME Board

The Curtiss-Wright / DY-4 / Ixthos IXD7232 Real-Time Signal Processing VME Board is designed to provide the high throughput, application flexibility, and performance required by real-time signal processing applications. Utilizing two ADSP-21020 IEEE floating-point digital signal processor (DSP) chips from Analog Devices, this board can achieve peak processing rates of 200MFLOPS, with sustained rates of 150MFLOPS. To maximize throughput, the IXD7232 architecture supplies each DSP with complete I/O and memory support. Each DSP has independent banks of 512KB data SRAM and 196KB (expandable to 960KB) of program SRAM. Each DSP can perform data transfers at rates up to 133MB/s, for a combined throughput of 266MB/s. DSPs can be interconnected on/between boards - providing nearly unlimited performance expansion. A key feature of the IXD7232 is the flexibility provided by its mezzanines. Each board holds two I/O mezzanines (IXI) and a global memory mezzanine (IXM) within a single 6U slot. The large variety of IXI mezzanines allow the user to configure the board for acquiring and processing virtually any type of analog or digital signal. The memory mezzanine provides reconfigurable global memory, allowing board optimization for a broad range of algorithms and applications. The IXD7232 also provides the user with a powerful A32:D32 master/slave VME interface supporting two DMA channels and BLT. Additional features, such as configurable interrupts, RS-232 ports, timers, and board synchronization, are built into the Board Controller to simplify real-time systems integration and software development efforts.
