PURPOSE:To eliminate the need of extending a different bus between other modules by constituting the system so that in the case a microprocessor reads out data from a memory, a bus can be allocated to other module after sending out an address to the bus. CONSTITUTION:A system bus controller...
Microprocessor system with a multibyte system bus 专利名称：Microprocessor system with a multibyte system bus 发明人：Oliver, Burton Laverne,Preston, David Charles 申请号：EP84105754.0 申请日：19840521 公开号：EP0127830A2 公开日：19841212 专利内容由知识产权出版社提供 专利附图：摘要：@ Bus command ...
Assume that a program and data are already entered in the memory; the microprocessor executes a program by reading all the data including instructions from the memory via the bus, and then processing these data in terms of instructions, then writing the result into memory via the bus. 2.1....
PURPOSE:To reduce the load of extension on software and improve the extendability of a system by converting system bus imformation between a microprocessor-applied device body and an additional device into serial data, and transferring the data. CONSTITUTION:When a CPU drives data information and a...
of plural times. CONSTITUTION:In case of write operation, by the first write command, an output (ADR/DAT7-0) of a microprocessor (muCPU)1 passes through a bidirec tional drive 5 and it is written on a memory I/O11 and a memory I/O which has been connected to a system bus. By ...
The data bus (the eight parallel conductors in Figure 9.5) on the right is a two-way path for transferring data in and out of the microprocessor unit. It is important to note that the microprocessor unit (MPU) can send data to or receive data from memory using the data bus. Programs ...
In a system with two microprocessors with one bus system each and a common read/write memory, the common read/write memory can be connected to the bus systems of the microprocessors via one switchable bus driver each. A handshake output (HMS) of one of the microprocessors, which is operated...
A SYSTEM IS DESCRIBED WHICH CONSISTS OF A 96-POLAR BUS SYSTEM (MAKBUS) WITH MUTUALLY COORDINATED PROCESSOR, OPERATING SYSTEM MEMORY, PERIPHERY AND EQUIPMENT INTERFACE CARDS IN THEEUROPEAN FORMAT. THE TRANSFER FROM AN 8-BIT TO A 16-BIT SYSTEM CAN BE IMPLEMENTED WITH EXISTING 8-BIT SOFTWARE IF...

Using PAL can save space, a very important factor in the miniaturization process. Examples of PAL applications include the BCD counter, the LS 138 emulator, and a priority interrupt encoder. The book also explains the operation and function of a microprocessor, the bus-based systems, analog-to...
