具有64位数据通路的 DS3805Futurebus~+I/O 协议控制器是一种单片解法,它用于板设计者和系统机构快速改变全部依从 B 形的 Futurebus~+的 B 形设计。具有64位数据通路控制器的 DS3805 I/O 协议基于 IEEE Futurebus~+896.1和896.2标准,并以强行的数据方式进行操作,它也包括用于64位数据正数奇偶性的数据通路 FIFO。DS3805FIFO 有128个字长,并处理使总线和过程的等待时间最少的多重同时事务处理。该控制器或是使用中央判优法或是使用分布式判优法与系统一起工作,该判优法包括整个中央判优请求和许可,该请求和许可处理不需要外部逻辑的芯片上的模块。
The DS3805Futurebus ~ + I / O protocol controller with 64-bit data path is a monolithic solution that allows board designers and system organizations to quickly change the B-shape design of all future B-shaped Futurebus ~ +. The DS3805 I / O protocol with 64-bit Datapath Controller is based on the IEEE Futurebus ~ + 896.1 and 896.2 standards and operates on data-for-data and includes datapath FIFOs for positive 64-bit data parity. The DS3805FIFO is 128 words long and handles multiple simultaneous transactions that minimize the bus and process latency. The controller either works with the system using either a central arbitration method or a distributed arbiter that includes the entire central arbitration request and permission that does not require external logic on-chip modules .
