GVA-395 DSP Hardware Accelerator Layout

The GVA-395 Modular DSP Development Platform consists of three Xilinx FPGAs. Two Virtex-II FPGAs are used for Analog Control

(ACX and AC) and two Virtex-II FPGAs are used for Data Processing (DP and DPX) respectively. The DPX FPGA also serves as the

primary FPGA for external communication. A Spartan-II FPGA (EI) is used for interfacing to provide a 5V tolerant external interface.

The platform’s general configuration consists of 12 interchangeable daughter PCBs that allow for a wide range of I/O capability. Eight of

the daughter PCBs are dedicated to the ACX FPGA. Two daughter PCBs are dedicated to the AC FPGA and an additional two daughter

PCBs are dedicated to the DP FPGA. Daughter PCB modules are to be as follows:

• 100 MSPS 12 bit A/D (GVA-AD9432)

• 170 MSPS 12 bit A/D (GVA-AD9430)

• 100 MSPS 14 bit A/D (GVA-AD6645)

• 100 MSPS 12 bit D/A (GVA-AD9762)

• 160 MSPS 14 bit D/A (GVA-AD9772)
