简化董事会设计和与控制PLD的调试

Today’s designers face a major challenge: How do I pack more functionality into a board, and do it faster and cheaper? The go-to approach to solving this problem is to implement data path or payload functions using highly integrated ASICs and SoCs. However, the design is not complete by simply connecting all the large devices together. Additional control path functions such as Power Management, level translation bridging functions, board specific glue logic, serial ports and I/O expansion may be needed. And the most convenient way to implement all these control path functions is to integrate them onto a single, programmable device such as a CPLD or a non-volatile FPGA – called the control PLD.

CPLD和非挥发性FPGA以其快速,廉价地整合所有控制路径函数的灵活性而闻名。控制PLD通常是系统中第一个打开的设备,也是以有序方式关闭所有其他组件后关闭的最后一个设备。尽管在设计的早期阶段几乎总是最终确定I/OS,但控制PLD中实现的逻辑通常在整个设计和调试周期内发生变化。设计师可以为给定的足迹自由添加更多逻辑。如果设备的逻辑利用率超过了设备的容量,则可以将设计迁移到具有较高逻辑密度(密度转移)的设备。即使将板部署在现场之后,这些设备也为用户提供了修改设计的选项,而无需将板带回工厂。

有时,逻辑能力提高或I/O可能还不够。bobappios下载地址视频桥接等应用需要更多的内部记忆以及改进的逻辑支持,以增加芯片图像缓冲,以改善大型监视器的图像清晰度。bob电子竞技俱乐部另一个示例是使用集成软处理器进行设计,其中内部代码大小在设计和调试过程中可能会超过片上资源。为了满足这种增加的资源需求,需要CPLD和非挥发性FPGA来支持更多嵌入式片上内存。bob电子竞技俱乐部

准备好也是CPLD的非易失性FPGA了吗?

我们的MACHXO3设备提供多种密度,I/O功能和包装,以覆盖需要CPLD到非挥发性FPGA的控制PLD应用程序。bobappios下载地址这些设备的增强功能使它们能够满足现代复杂系统的控制需求。最近添加的Machxo3L-9400和Machxo3LF-9400设备,带有384 I/OS,9400 LUTS和将近0.5MB的嵌入式RAM是为了直接回应喜欢Machx03家族灵活性的客户的反馈,但正在寻找更多的客户,但正在寻找更多,但正在寻找更多I/OS和更具成本效益的软件包。这些新设备是理想的选择服务器,通信,工业和展示市场and will simplify the use of the most advanced components while staying on budget and on time. Low end of the MachXO3 family of devices bring higher end features into CPLD devices. Now even the simpler systems can benefit by higher end non-volatile FPGA features.

随着董事会变得更加复杂,I/OS的逻辑,性能和数量将需要跟上。随着我们的扩大家庭和我们的特征Lattice MachXO3线条,您,设计师将准备应对挑战。
