    Abstract: A memory device comprising a package (10) which has a plurality of terminals (12), at predetermined positions for inspecting program, and switching means (30) which is arranged in the package (10) and which switches the first and second operations. In the first operation, a rewritable read-only memory is connected to the terminals for inspecting program. In the second operation, inspection means (8) is connected to the terminals for inspecting program. In the first operation of the piggyback type, a rewritable ROM (EPROM) is connected to the terminals for program inspection of the package. In the second operation of the evaluator type, inspection means is connected to the terminals for program inspection of the package and is used as switching means, so that the operation can be automatically switched by a multiplication select circuit. Therefore the signal lines can be multiplexed to a great extent, and the piggyback-type chip and the evaluator-type chip can be used as the same device. Further, the same package can be used to accommodate the chips. This eliminates the need of separately developing the piggyback-type chip and the evaluator-type chip, and to separately produce the packages, contributing to shorten the time for developement and to reduce the cost of developement. Moreover, the piggyback-type chip, the evaluator-type chip and the mask ROM mounted chip can be made of the same pin arrangements. Therefore, the program can be evaluated by the evaluator-type chip with the mask ROM mounting board which is a final product, without requiring the traditionally employed interface substrate or the like.

    Abstract: A current driver (10) is disclosed that includes an array of current buffers (80) and a program control circuit (12). The program control circuit (12) responds to an externally generated programming signal to generate buffer direction control, daisy chain configuration control, and tristate control signals. The buffers of the array of current buffers (80) are individually programmed by the direction control and the daisy chain configuration control signals to transmit data in one of a forward and reverse direction and to daisy chain a buffer (80) to a preceding buffer (80), respectively. The array of current buffers (80) is responsive to the tristate control signal to operate in a tristate mode. The array of current buffers (80) may be reprogrammed in response to a reset signal.

    Abstract: An emulation controller (12) connected at a pin boundary of an integrated circuit (14) can be provided with concurrent access to concurrent debug signal activity of first and second data processing cores (core 2, core 1) embedded within the integrated circuit. A first signal path is provided from the first data processing core to a first pin (39) of the integrated circuit, for carrying a selected debug signal of the first data processing core to the first pin. A second signal path is provided from the second data processing core to the first pin of the integrated circuit for carrying a selected debug signal of the second data processing core to the first pin. A third signal path is provided from the second data processing core to a second pin (41) of the integrated circuit for carrying the selected debug signal of the second data processing core to the second pin.

    Abstract: An emulation controller (12) located externally of an integrated circuit (14) can be provided with timing information indicative of operation of an internal clock of the integrated circuit that drives internal data processing activity of the integrated circuit. In response to each cycle of the internal clock, a corresponding digital bit is produced to represent the internal clock cycle, and the digital bits are output to the emulation controller at an output clock rate that differs from the clock rate of the internal clock.
