This paper presents an efficient architecture for circle detection using Hough transform. The architecture adopts the scanline-based ball detection algorithm for the edge detection stage and edge-flag algorithm for the voting process. To bolster the performance of the voting process, when drawing a circle, we divide it into 16 sub-parts and compute the parts in parallel. The proposed design employs an internal memory block for the edge list. Our simulation results show that the benchmark images in the VGA size of 640 x 480 are processed within 10ms, which indicates that the proposed architecture can satisfy the speed requirements of most real world applications.

“…The double buffering scheme is adopted between the Rasterizer and PixelPipe for parallelization. For efficiency in rendering in terms of internal memory usage, an edge-flag algorithm similar to the one proposed by Shen et al [14] is adopted in this module. The edge-flag algorithm in [14] uses one counter per pixel, whereas the usual edge-flag algorithms [4] use one counter per sample point.…”

The edge-flag algorithm in [14] uses one counter per pixel, whereas the usual edge-flag algorithms [4] use one counter per sample point. Thus, the algorithm in [14] consumes less memory and performs less computations, and operates well unless multiple edges overlap with each other in one path, which is very unusual in practical applications.…”

SUMMARYThis paper introduces a hardware engine for rendering two-dimensional vector graphics based on the OpenVG standard in portable devices. We focus on two design challenges posed by the rendering engines: the number of vertices to represent the images and the amount of memory usage. Redundant vertices are eliminated using adaptive tessellation, in which the redundancy can be judged using a proposed cost-per-quality measure. A simplified edge-flag rendering algorithm and the scanline-based rendering scheme are adopted to reduce external memory access. The designed rendering engine occupies approximately 173K gates and can satisfy real-time requirements of many applications when it is implemented using a 0.18 μm, 1.8 V CMOS standard cell library. An FPGA prototype using a system-on-a-chip platform has been developed and tested.
