multiprocessor communication system/ C5220 Computer architectureIn the paper interrupts in modular microprogramming and a special sequencing mechanism have been introduced. The proposed stored solution has the following properties. The execution of any microprogram stored in the control memory can be ...
The next step in architecture development was namedx2APIC. The number of possible CPUs in the system was increased to 2^32. These controllers can work in a backwards compatibility mode with xAPIC, or they can work in the new x2APIC mode. In this new mode controller programming is not do...
Receive packet steering (RPS) balances the load of soft interrupts among CPUs. In short, the NIC driver calculates a hash ID for each stream by using a quadruplet (SIP, SPORT, DIP, and DPORT), and the interrupt handler allocates the hash ID to the corresponding CPU, thus fully utilizing...
In daisy chaining system all the devices are connected in a serial form. The interrupt line request is common to all devices. If any device has interrupt signal in low level state then interrupt line goes to low level state and enables the interrupt input in the CPU. When there is no int...
external interrupt by toggling the appropriate port pin. External interrupt 0 is triggered by either a changing edge or level on I/O PORT 3.2. You can change the state of the pin by writing to the PORT3 VTREG. The following assignments may be entered in the command window to toggle PORT...
It also means that when the code is in the middle of an interrupt service routine it can (and will) get interrupted by the SAME interrupt. So on this architecture (M68K and Coldfire) you should never use this NMI except for "unrecoverable and serious errors". It isn't an "edge ...
This invention relates to a method of processing interrupts in a digital computer system. Newly designed microprocessors may include enlarged memory addressing facilities and revised architecture which result in enhanced capabilities. When such microprocessors are used in new computer systems, they often pr...
I am looking for a simple timer interrupt arrangement in my application. No hardware is involved, it's purely software.I have an application that runs on a Windows 2003 Server, written in C, developed in Visual Studio 2008. Without going into unnecessary detail, essentially, I require a ...
An additional benefit is that less processing power and less buffering is required to be kept in reserve when using a deterministic as opposed to a non-deterministic architecture resulting in less costly processor configuration. A further benefit is that because it is deterministic, the invention fac...
A distributed computer system includes a host CPU, a network/host bridge, a network/I/O bridge and one or more I/O devices. The host CPU can generate a locked host transaction, which is wrapped in a packet and transmitted over a network to the remote I/O device for replay. The remote...
