Abstract:
A high-integrity, N-lane computer processing module (Module), N being an integer greater than or equal to two. The Module comprises one Hosted Application Element and I/O Element per processing lane, a Time Management unit (TM) configured to determine an equivalent time value for a request made by software running on each of the N processing lanes, irrespective as to when the request is actually received and acted on by each of the N processing lanes, and a Critical Regions Management unit (CRM) configured to enable critical regions within the respective lane to be identified and synchronized across all of the N processing lanes.
Abstract:
A multiprocessor system includes a number of sub-processor systems, each substantially identically constructed, and each comprising a central processing unit (CPU), and at least one I/O device, interconnected by routing apparatus that also interconnects the sub-processor systems. A CPU of any one of the sub-processor systems may communicate, through the routing elements, with any I/O device of the system, or with any CPU of the system. Communications between I/O devices and CPUs is by packetized messages. Interrupts from I/O devices are communicated from the I/O devices to the CPUs (or from one CPU to another CPU) as message packets. CPUs and I/O devices may write to, or read from, memory of a CPU of the system. Memory protection is provided by an access validation method maintained by each CPU in which CPUs and/or I/O devices are provided with a validation to read/write memory of that CPU, without which memory access is denied.
Abstract in simplified Chinese:实例揭示一多核电路,具有一主要内核联结高速缓存之一主要部分以及一次级内核联结高速缓存之一次级部分。高速缓存之次级部分系高速缓存之主要部分的备份。此外,多核电路之实例提供一控制电路,其因应在主要内核处侦测到之错误而致能次级内核之运作,其中高速缓存之次级部分被次级内核致能以恢复主要内核之运作。
Abstract in simplified Chinese:本发明揭示一种供于一主机系统与一数据存储系统间传输数据的系统与方法。该系统包括一界面,其运用一以文档为主之协定,以于该数据存储系统与该主机系统间传输数据,其中该数据存储系统包括一第一大量存储设备与一第二大量存储设备;其中该第一大量存储设备系一固态非挥发性内存设备,而该第二大量存储设备系一非固态内存设备。该第一大量存储设备系一闪存设备,其作为一主要存储设备,并会以文档为主一件件地将数据存储起来。该第二大量存储设备系一磁盘驱动器,其作为次要存储设备,并会存储经由一逻辑界面而接收的数据。
