Abstract:
Microprocessor main programs and their interrupt handling routines are written in a high level programming language such as C. Each is compiled separately, and each is compiled invoking a compiler option which commands the compiler to not use a given set of registers in the compiled code. Post-processing is then performed on the compiled interrupt code to replace accesses to a first set of registers with accesses to the given set of registers. The result is that while both the main program and the interrupt handler were written in C, the compiled code for each employs different registers. This allows context switching from the main program to the interrupt handler and back again with almost none of the overhead traditionally associated with context switching register save and restore operations during exception handling.
Abstract:
An asynchronous transfer mode (ATM) digital electronic communication system includes an ATM communication system interconnection and termination unit (ATMCSI/TU). This ATMCSI/TU includes both a programmable microprocessor and several hardware-implemented coprocessors. The hardware-implemented coprocessors are under control of the microprocessor, and are dedicated to the performing of repetitive tasks. Thus, the microprocessor is freed to perform supervisory tasks in the ATM in addition to performing tasks associated with actual communication of digital data packages (i.e., CS-PDU's) in the ATM system. Thus, the APU is freed from doing repetitive data manipulation tasks, while these tasks are performed by one or more hardware-implemented coprocessors using memory mapped data structures and linked lists of data.
Abstract:
A cell scheduler for a distributed shared memory switch architecture including a controller for scheduling transmissions of cells from output queues of the switch structure pursuant to one of several different scheduling modes. The controller receives a mode selection input, segregates the output queues into groups, assigns priority rankings to the groups, and applies one of scheduling disciplines at each group of output queues as determined by the mode selection input and the priority rankings. The groups of output queues include a group of per-Virtual Channel (VC) queues and at least one group of First In-First Out (FIFO) queues. The scheduling disciplines include a Weighted Fair Queuing (WFQ) scheduling discipline applied by the controller at the group of per-VC queues and a Round Robin (RR) scheduling discipline applied by the controller at the at least one group of FIFO queues. The priority rankings comprising a highest priority ranking which is assigned to the group of per-VC queues.
