t可编程的SOC:两芯片系统与真正单t芯片系统 t系统级集成仍然是半导体产业中的t标题新闻。正在进行的工作把几乎是全t部的系统功能集成到单个硅片上。片上t系统（SOC）可以提供更好的性能、更低t的功耗、更小的印制板空间,以及更低的t成本,因而受到人们的青睐。片上系统传t统上一直是用掩模ASIC去实现。但是,tASIC的不可重用的工程费用达到每次设t计25万美元或更多,最低订购量大,设t计周期长。因此,只适合在批量大、能够t承受得起这种成本的项目上使用。t 几家IC厂商已经推出一种新的混合t型SOC器件,即可编程片上系统。它们 Programmable SOC: Two-chip systems with true single-chip system integration at the system level are still the headlines in the semiconductor industry. Ongoing work integrates almost all the system functions of a single part into a single silicon chip. On-chip systems are favored for better performance, lower power consumption, smaller board space, and lower cost. System-on-chip system has been used to mask mask ASIC to achieve. However, the non-reusable engineering costs of tASIC can reach $ 250,000 or more each time, and the minimum order quantity is large, assuming a long period of t. Therefore, only suitable for large quantities, can t affordable to use this project. Several IC vendors have introduced a new hybrid t-type SOC device, a programmable system-on-chip. they
