    • For use in a data communication channel for transferring data between a host processor (101) and a remote data center (102), the disclosed direct memory access interface arrangement (103) comprises an input (203) and an output (204) register, a direct memory access interface controller (206), and a host access buffer (801) for loading a peripheral processor program into a random access memory (207). Connected between the data (251) and address buses (252) of a peripheral unit, the host access buffer transfers controller address signals from the host processor on the data bus to the address bus to write an initial memory address and program word count into registers of the controller. In response to write orders from the host processor, the controller uses the initial memory address and program word count to address locations in the memory in which the peripheral processor program may be loaded.

    • PROBLEM TO BE SOLVED: To provide a processor controller capable of performing polling processing for a plurality of modules while suppressing a load on a processor. SOLUTION: Polling processors 11c, 12c respectively output polling signals PS1, PS2 for stopping supply of signals to a processor core 1 upon access request from the processor core 1 when respective modules M1, M2 are performing respective processing. A polling selector 5 outputs to a clock control circuit 6 a WAIT signal WA for suspending a clock signal CL to be outputted to the processor core 1 based on designation by a single wait status register 11b or a multi-wait status register 11a. The clock control circuit 6 suspends the clock signal CL to be provided to the processor core 1 based on the WAIT signal outputted from the polling selector 5. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供能够在抑制处理器上的负载的同时对多个模块进行轮询处理的处理器控制器。 解决方案:当各个模块M1,M2进行各自的处理时,轮询处理器11c,12c分别输出轮询信号PS1,PS2,用于在来自处理器核心1的访问请求时停止向处理器核心1提供信号。 轮询选择器5基于单个等待状态寄存器11b或多等待状态寄存器11a的指定,向时钟控制电路6输出WAIT信号WA,用于挂起要输出到处理器核心1的时钟信号CL。 时钟控制电路6基于从轮询选择器5输出的WAIT信号暂停提供给处理器核心1的时钟信号C.(C)2007,JPO&INPIT

    • PURPOSE:To improve the efficiency of a system by constituting a data bus as a dual structure, dividing a memory into two blocks and executing memory access processing from a CPU and DMA data transfer in parallel. CONSTITUTION:The data bus is constituted of a double bus of A.1 and B.2 and the memory is divided into two blocks #1.5, #2.6. The titied circuit is constituted by a CPU3, a directly memory access controller (DMAC) 4, an I/O device 7, etc. Processing data previously stored from the CPU3 in memories 5, 6 are transferred from the memories 5, 6 to an output device 7 by the DMAC4. On the other hand, data rapidly transferred from the input device 7 to the memories 5, 6 are processed by the CPU3. Thus, the memory access from the CPU3 and data transfer based upon the DMAC4 can be executed in parallel and the high-speed data processing can be attained.
    • 目的:通过构成数据总线作为双重结构来提高系统的效率,将存储器分为两个块,并且从CPU和DMA数据传输并行执行存储器访问处理。 构成:数据总线由A.1和B.2的双总线构成,存储器分为两个块#1.5,#2.6。 所设置的电路由CPU3,直接存储器访问控制器(DMAC)4,I / O设备7等构成。从存储器5,6中CPU3预先存储的处理数据从存储器5,6传送到 输出设备7由DMAC4。 另一方面,由CPU3处理从输入装置7快速传送到存储器5,6的数据。 因此,可以并行地执行来自CPU3的存储器访问和基于DMAC4的数据传送,并且可以实现高速数据处理。
