    摘要: A programmable interrupt controller having a plurality of interrupt request inquest inputs and an interrupt request output for connection to a central processing unit (CPU) includes means for interrupting the CPU over the interrupt request output responsive to an interrupt request from any one of the interrupt request inputs and a priority resolver for assigning a priority position to each of the interrupt request inputs to create an interrupt priority hierarchy. The interrupt controller is programmable such that each interrupt request input may be independently established as responsive to either edge-triggered or level-triggered interrupt requests on a per interrupt basis. An initialization command word register of the interrupt controller has a bit corresponding to each of the interrupt request inputs. Programming each of the bits of the register to one of two states determines whether corresponding interrupt request inputs are edge-sensitive or level-sensitive.

    摘要: A personal computer has two possible memory sizes differing by the maximum number SIMMs that can be installed. Each SIMM stores presence detect bits indicating the size and speed of the SIMM. An I/O controller includes a memory detect port which is used to read the presence detect bits from the SIMMs. The controller further includes a logic circuit that is set in accordance with the memory size to selectively control driving the presence detect bits or empty socket bits onto a data bus.

    摘要: A high performance, low power up/down counter is set forth. The counter presented is controlled by two clock pulses, an up pulse and a down pulse, and updates all bits of the counter in parallel. These bits are then latched using a scannable pulsed limited output switching dynamic logic latch. By using a limited switch dynamic logic latch, the counter is able to utilize the speed of dynamic logic without requiring the traditional dynamic logic power. The area saved and speed gained by using a dynamic latch is significant compared to a typical edge-triggered flip-flop. Additionally, by computing all the next count state bits in parallel, the counter reduces an overall count computation delay by eliminating the counter ripple.
