Today's FPGAs are capable of performing complex Image Processing schemes. In this paper we introduce a Configurable Zero Stall Image-Processing Pipelined Architecture. We define the handshake and discuss limitation resulting from configurability and complexity. We then present our solution for these issues allowing a simple yet effective circuit where no delay is introduced even though the output...
The capacity of Flash on-board is generally small, the data will be lost after SDRAM power-down, and they can not easily transfer the data to a computer. In order to meet with large-capacity storage needs in the image processing system, this paper uses CF card as removable storage media. It mainly introduces the working principle of CF (Compact Flash) cards and the principle of FAT16 file system,...
Modern FPGA chips, with their larger memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high density FPGAs it is now possible to implement a high performance VLIW processor core in an FPGA. Architecture based on Very Long Instruction Word (VLIW) processors are an optimal choice in the attempt to obtain high performance...
This paper describes a FPGA-based verification methodology for the image signal processor (ISP) of system-on-chip (SoC) type CMOS image sensor. To make a verification environment, the complete ASIC prototyping system, the ARM7 TDMI CoreTile board and external interface boards - the sensor board, the USB board and the switch board - are used. As a verification method, 4-step verification strategy comprised...
Floating-point fast Fourier transform (FFT) processor and coordinate rotation digital computer (CORDIC) element play important roles in communication and radar applications. But even with the rapid development of large-scale integrated circuit, it is usually impractical to implement these floating-point computations on FPGA, as they will consume a large amount of chip resources. In this paper, a compact...
