Abstract: PURPOSE:To enable complicate jump wirings, and to improve the degree of freedom on the design of a printed wiring board by respectively forming first and second function elements onto the surface and the rear of a square plate- shaped insulating substrate, separately connecting both ends of these elements to diagonal two electrodes in terminal electrodes shaped at the four corners of the substrate and coating the surfaces of the elements with insulating films. CONSTITUTION:Two pairs of electrodes consisting of terminal electrodes 5a, 5b and 6a, 6b are formed respectively at the four corners of a square-shaped insulating substrate 1, and a first function element 2a such as a resistor is shaped to the surface of the substrate 1. Leading-out electrodes 3a and 4a are connected separately at both ends of the element 2a, and connected to the electrodes 5a and 6b at positions diagonal to these electrodes 3a and 4a. A second function element 2b formed to the rear of the substrate 1 is also connected to the electrodes 5b and 6a through leading-out electrodes 3b and 4b.

Title: Microprocessor with address converting function
Inventor: KUWATA AKIRA
IPC: G06F12/02
Filed: 1989-08-18
Abstract: PURPOSE:To reduce the number of parts of a microprocessor by using the address converting function incorporated in a CPU to convert the address outputted from an external bus master. CONSTITUTION:When a CPU 100 starts a bus cycle, a multiplexer MPX 102 selects a CPU address bus 19-14. An address converting part 101 converts the address of the bus 19-14 to that of a CPU address bus 23-14 and outputs it to the address bus 23-14. When a DMA controller 103 sets a request signal HLDRQ to the high level, the CPU 100 transfers the bus use right to the controller 103. When getting the bus use right, the controller 103 outputs the address and a control signal. The address of the DMA address bus 19-14 is inputted to the converting part 101 through the MPX 102. The converting part 101 converts the inputted address of the DMA address bus 19-14 to an extended address and outputs it to the CPU address bus 23-14. By this constitution, it is unnecessary to provide the address converting function on the external and the number of parts is reduced.
