A microprocessor includes a data bus and an address bus. The address bus has first and second sections coupled together in series by bus switch circuitry. The microprocessor also includes control circuitry for controlling various data transfers in the microprocessor. The bus switch circuitry includes ...
PURPOSE: To easily test the stack fault of a bus by providing plural common input/output(CIO) bus driver which is connected between a microprocessor and the respective buses to be a test object. CONSTITUTION: A counter 14 which is reset by a reset signal 12 inputted from a microprocessor is...
Microprocessor comprises a CPU (2), a data bus (4) and an address bus (8) for access to program memory space with a size greater that that addressable with the address bus. Accordingly the memory space is divided into pages, which are addressed by the processor using a page register (PR...

The ALU, ... KC Mcdonough,KM Guttag,GE...
A multiplexed address and data bus system provides a minimum pin count with byte enable and burst address counter support. The partitioning of the address ... PA Bourekas,A Willenz,Y Mor,... 被引量: 0发表: 1995年 CONTROLLER HAVING MAIN MICROPROCESSOR AND PROCESSOR INTERFACE TO BUS TRANSMITTIN...
An address information line of a microprocessor informs a memory management unit of such address information that a current address is identical to an address before one bus-cycle or two bus-cycles or is a new address. Since the address information line has a light load, the address information...
An adapter converts an instruction-controlled processor such as a microprocessor into a PROM programming apparatus. The adapter is compatible with the type of processor having readout circuitry for applying a multibit signal via an internal address bus to a processor socket into which an addressable...
