摘要： In an information processing apparatus, a user having no knowledge of a designer of an LSI modifies a floorplan of the LSI without deteriorating the performance of the LSI. The designer who designs the LSI uses a circuit designing apparatus to store circuit information including a functions of each of blocks constituting the LSI, a floorplan regarding allocation of the blocks, and evaluation indices which are the know-how of the designer, with being associated with each other. The user uses a floorplan modifying apparatus to modify the floorplan and to evaluate the modified floorplan according to the evaluation indices.

摘要： A replicated controller and a fault recovery method therefor which can restore a faulty system to a normal state without interrupting operation of an equipment, even in an equipment controller performing processing with short operating periods.In a fault recovery method for a replicated controller, control data is divided into a plurality of blocks on the basis of dependency of the blocks, and a plurality of blocks are transferred in a sequential order of superiority of the dependency from the normally operating system to the faulty system in a period over a plurality of operating periods. BY this, even in an equipment controller performing processing at a short operating period, the system, in which failure is caused, can be restored into normal state without interrupting operation of the equipment.

摘要： There is provided a technique which reduces an average processing time of low-priority accesses with suppressing an average delay increase of a high-priority access processing even in a case where high-priority access request and a low-request access request are simultaneously generated to a shared access processing unit and high-priority accesses are continuously generated. And, there is provided an access arbitration equipment comprising: an issued access request retention unit; a first interval determination circuit; and a second interval determination circuit.

摘要： A data processing device that does not depend on the type of data, has wide application range, and can reduce memory access in data transfer via a buffer arranged in a memory is provided. In a data processing device including a plurality of data processing units and a memory commonly accessed by the data processing units, the data processing units transfer the transfer data via the memory, the transfer data and the compressed data of the transfer data are held in the memory. When read request for the data is issued, the compressed data is expanded and the expanded data is stored in the expanding data buffer. While the compressed data is being expanded, the original data is read from the memory, and after the expanded data is stored in the expanding data buffer, the expanded data is read from the expanding data buffer.

摘要： In logical compound of inter-subblock paths, circuits including all inter-subblock paths are generated. Logical compound is conducted for the generated circuits to achieve logical compound of the inter-subblock paths. By treating inter-subblock paths as intra-subblock paths, no input/output delay restriction is required for the logical compound of inter-subblock paths. This makes it possible to fully use performance of the logical compound tool, and hence the inter-subblock paths can be optimized through one operation of the processing.

摘要： A prefetch address calculation unit detects a branch instruction and a data access instruction to be reliably executed from a series of instruction included in an entry that is stored in a buffer at 1 cycle and outputs a prefetch request of its target address to a control unit. Then, decoding types of the series of instruction that is included in the entry, and setting it at an instruction type flag, the prefetch address calculation unit masks the output of the instruction type flag that has been executed by using an address signal of the instruction that is being executing presently and outputs a location of the instruction for issuing a prefetch request. By a signal from a control unit, the prefetch address calculation unit clears an instruction type flag corresponding to the instruction that issued the prefetch request.

摘要： A micro-controller includes a dictionary memory for storing instruction codes which appear in a program, and a compressed code memory for storing compressed codes each converted from each of the instruction codes included in the program. Each compressed code has a word length sufficiently long to identify all instruction codes included in the program. Each compressed code has a value indicative of an address in the dictionary memory at which an associated instruction code is stored. The micro-controller is responsive to an instruction code read request which specifies an address of a compressed code to read the compressed code stored in the specified address in the compressed code memory, and to subsequently read an instruction code stored in an address indicated by the compressed code in the dictionary memory.
