Abstract: A high performance single package multi-chip module multiplies the logic density of the highest density monolithic programmable logic device (PLD). A dual-sided substrate carries multiple prepackaged PLDs on a top side and a field programmable interconnect (FPIC) die on a bottom side. The prepackaged PLDs and the ability to use the substrate as a burn-in vehicle for the FPIC die results in reliable and reworkable assembly process with minimized yield loss.

Abstract: Programmable logic array devices are programmed from programming devices in networks that facilitate programming any number of such logic devices with programs of any size or complexity. The source of programming data and control may be a microprocessor or one or more serial EPROMs, one EPROM being equipped with a clock circuit. Several parallel data streams may be used to speed up the programming operation. A clock circuit with a programmably variable speed may be provided to facilitate programming logic devices with different speed characteristics. The programming protocol may include an acknowledgment from the logic device(s) to the programming data source after each programming data transmission so that the source can automatically transmit programming data at the speed at which the logic device is able to accept that data.

Abstract: A high performance single package multi-chip module multiplies the logic density of the highest density monolithic programmable logic device (PLD). A dual-sided substrate carries multiple prepackaged PLDs on a top side and a field programmable interconnect (FPIC) die on a bottom side. The input/output terminals of the PLDs are interconnected with the FPIC die in a scrambled fashion to reduce signal skew.

Abstract: Apparatus and methods for configuring a plurality of programmable logic devices which include the steps of providing a source of configuration data and transferring the configuration data directly from the source to each of the programmable logic devices. In some embodiments, the methods permit the programmable logic devices to configure themselves without the intervention of an intelligent host such as a CPU, a microcontroller, or other types of intelligent logic. In other embodiments, configuration data files are used in conjunction with an intelligent host to configure the programmable logic devices. Configuration is performed at power-up or, alternatively, under user or software control.
