摘要： This invention discloses an arithmetic processor which represents internal arithmetic operands as signed-digit numbers, each digit of which may have either positive, zero, or negative values and which executes addition of a plurality of numbers each of whose most significant digit is offset with respect to the other numbers. The arithmetic processor includes an adder tree which is so constituted that a pair of said plurality of numbers are added to obtain a partial sum and further pairs of partial sums are successively added to obtain a final sum of all numbers. The arithmetic processor further comprises first means for adding a portion of the two numbers where both digits are present, second means for causing a lower order portion where only one of the numbers has a digit present to directly become part of the sum, third means for retaining or outputting a carry created by the first means, and fourth means for adding the carry created in each add stage of the adder tree to the later add stages of the adder tree to obtain the sum.

摘要： In the memory exclusive control device having a CPU-1 accessible to both a common memory and first memory devices, the CPU-1 is prohibited from accessing to the common memory device (105) during OFF state of an access permission flag, and when the access permissive flag ON is established by TCS (111), the gate of the access permitting unit (103) is opened to thereby permit the CPU-1 to access to the common memory device (105). Thus, the memory exclusive control can be realized for transferring a desired program to be processed to the address space of the first memory device, allowing omission of a third memory device.

摘要： For reducing time required for error correction in an error correction device, data are transferred from a buffer memory not only to a syndrome calculator but also to an error detector at the same time, and until the syndrome calculator detects an error-containing code, the error detector performs error detection in parallel with the syndrome calculation done by the syndrome calculator. During error detection after the error corrector corrects the error, mid-term results of the error detection obtained before an error-containing code is detected are used. Consequently, it becomes unnecessary to transfer all data from the buffer memory to the error detector, thereby making execution of an error detection process possible at a halfway point.

摘要： In a processor having a central processing unit, an instruction cache and a data cache, a bus controller is provided for controlling giving and receiving of a signal between internal instruction and data buses and external bus. Upon concurrent miss of instruction cache and data cache, the bus controller executes an external instruction access with priority in case where the external instruction access is a same page access as a previous external DRAM access, and executes an external data access in the other cases. Thereby, the cycle number required for the external access is reduced, while reducing the number of instruction execution cycles as a total.

摘要： A control system for controlling a cache tag memory has an address conversion device which includes an associative storage for storing logical addresses, a random access memory for storing physical addresses, and a hit-signal generating circuit for generating a hit signal, a word selecting signal and at least one control signal. The hit signal indicates that a hit has occurred between a logical address stored in the associative storage and an input logical address. The address conversion device controls the reading operation of a tag address stored in the cache tag memory by using the control signal generated by the hit-signal generating circuit in synchronization with a word selecting signal used in the reading operation of a physical address stored in the random access memory such that the physical address and the tag address are read at substantially the same time. Further, this address conversion device controls a reading operation of the data stored in the cache memory by reading the physical address and the tag address at substantially the same time and by using a second control signal generated by the hit-signal generating circuit in synchronization with the word selecting signal. Moreover, the address conversion device controls the reading of data from the cache memory and the production of a cache hit signal, which is generated when the physical address matches the logical address. Accordingly, a high-performance system is achieved.
