JPEG2000 hardware compression system solution VID475 Description The VID475 features a JPEG2000 hardware compression solution. It is based on the ADV212 codec devices suitable for on-the-fly compression prior or after the imaging processing implemented on the Virtex-4 FPGA device. The VID475 has two Xilinx Virtex-4 FPGA devices and some fast on-board SRAM and DRAM memory resources. It is the most efficient hardware compression solution available with embedded processing power. The flexibility of the architecture and the use of the Camera-Link standard makes this solution universal for digital imaging systems. 主要特性： JPEG 2000 compression with two ADV212 CODEC devices Camera-Link Base configuration via two mini CL connectors FPGA High speed DSP processing in two Xilinx Virtex-4 ® FPGA XC4VSX55, XC4VLX40, XC4VLX60, XC4VLX80, XC4VLX100 or XC4VLX160 XC4VFX20 or XC4VFX60 with embedded PowerPC RISC processor FPGA configuration on-board storage Off-the-shelf IP cores for real time compression (JPEG2000, edge detection) FPGA firmware design services available upon request Memory 2 x 32M x 16 DDR2 SDRAM (128MB) 4 x 2M x 32 QDR2 SRAM devices (32MB) 128Mbit flash device PCI interface PCI-X 64-bit 133MHz, 3.3V PCI-X/PCI 64/32-bit 66MHz, 3.3V PCI 64/32-bit 33MHz, 3.3V PCI express 4 lanes PMC Pn4 64 I/O connected to FPGA A Measured sustained bandwidth 64-bit 133MHz = 760Mbytes/s 64-bit 66MHz = 450Mbytes/s 32-bit 33MHz = 120Mbytes/s Software Support FPGA reference design API, documentation and sample source code Software utility to program on-board Flash with FPGA configuration data Device driver for Windows 2000/XP, Linux and VxWorks Test /demonstration application 主要应用： Digital film compression and storage Satellite video frame recording instruments High-definition X-ray frame recording Medical line scan cameras Microscopy, radiology and biopsy analysis Mobile imagery instruments Low-weight digital video broadcasting Real-time loss-less imaging compression  图1.
