为提高字符发生器数据处理能力和笔划书写性能,设计一种新型笔划式字符发生器。采用具有双处理器双总线的DSP作为主处理器,采用FPGA集成矢量发生器。利用DSP的握手式DMA通道,加上矢量指令管理单元的时序配合,完成矢量发生器对矢量指令的自主申请和获取,实现字符发生器数据处理与笔划书写的并行管理,提高字符发生器的平均书写速度和笔划书写均匀性。着重介绍字符发生器的组成、工作原理、工作流程及矢量指令管理单元的时序设计。 In order to improve the character generator data processing ability and stroke writing performance, a new type of stroke character generator is designed. Using a dual-processor dual-bus DSP as the main processor, the use of FPGA integrated vector generator. DSP DSP’s handshake-type DMA channel, coupled with the timing of the vector command management unit to complete the vector generator to autonomously apply for vector instructions and access to achieve character generator data processing and stroke writing parallel management to improve the average of the character generator Writing speed and stroke writing uniformity. Characterize the composition of the generator, working principle, workflow and vector instruction management unit timing design.
