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...
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...
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...
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 ...
A method, system, and article of manufacture to efficiently support interrupts of a computer system. A message-based interrupt from a device of the computer system is intercepted. A fake line-based interrupt for the device corresponding to the message-based interrupt is determined, wherein an ope...
DOS Function Calls (INT 21h) The INT 21h instruction activates a DOS function call The function number (0-255) is placed in the AH register before invoking INT 21h Some functions require that you assign values to certain registers before invoking INT 21h Some functions return values in register...
A technique to enable efficient interrupt communication within a computer system. In one embodiment, an advanced programmable interrupt controller (APIC) is interfaced via a set of
