摘要： In a computer system having a plurality of processing elements (PE#0 to PE#n) and adopting a distributed-shared-memory-type multiprocessor scheme, a master PE (for example, PE#0) executing a multi PE loader transfers an MPMD program for PE#k to a predetermined area of memory space of PE#0 to which a unique memory (LM) of PE#k is temporally allocated. The LMs of PE#1 to PE#n can be allocated to different areas of the memory space of PE#0 respectively, or can be allocated the same area thereof.

摘要： According to one aspect of embodiments, a multiprocessor system includes a cache memory corresponding to each of the processors, a hierarchy setting register in which the hierarchical level of each cache memory is set, an access control unit that controls access between each cache memory. The hierarchical level of the cache memory for each processor is stored in a rewritable hierarchy setting register. Each processor handles a cache memory corresponding to another processor as the cache memory having a deeper hierarchy than the cache memory corresponding to the each processor. As the result, each processor can access all the cache memories, and therefore the efficiency of cache memory utilization can be improved and the hierarchical level can be set so that the latency becomes optimal for each application.

摘要： In a cache memory control method and computer of the present invention, a cache memory is connected to a main memory and divided into a plurality of cache blocks, and a lock/unlock signal is supplied to the cache memory to either set a replace-inhibition state of at least one of the cache blocks in which replacing at least one of the cache blocks to the main memory is inhibited, or reset the replace-inhibition state of at least one of the cache clocks such that replacing at least one of the cache block to the main memory is allowed. Either reading or writing of the main memory is performed by using the remaining cache blocks of the cache memory, other than the at least one of the cache blocks, such that, when the replace-inhibition state is set by the lock/unlock signal, replacing the at least one of the cache blocks to the main memory is inhibited during the reading or writing of the main memory.

摘要： A data processing apparatus temporarily stores data to a cache write buffer and then stores the data in a cache storing device. The cache storage device performs a data storage operation with precedence over another operation even if a store instruction contends with a read instruction for accessing the cache storing device. A storage request low signal, sent from a cache write buffer controlling device to a cache controlling device, allows a read request to have precedence over a store instruction even when there is data stored in the cache write buffer waiting to be transferred to the cache storing device in response to the store instruction. However, when the read instruction contends with the store instruction and a state transition signal, such as an instruction cancellation signal generated from an instruction controlling device, is detected, the cache write buffer controlling device changes the output signal to a storage request high signal that causes the storage operation to have precedence over the read operation.

摘要： An address buffer that stores information used to access a data memory is disposed in a cache unit that supplies data such as an instruction code to an instruction executing unit. A tag memory and a data memory are independently accessed. The data memory is accessed corresponding to access information stored in the address buffer. Data is output from the data memory in the input order of data requests. When a data release signal is not received from the instruction executing unit, since access information is buffered in the address buffer, a large data buffer for storing the output data of the data memory is not required. In addition, in an associative type cache unit, the tag memory and the address buffer can be formed in the same memory.

摘要： When an input address AD is previously stored in a register 211, if a matching signal EQ1 is active, then an address queue control circuit 19A latches an offset of the input address AD into a register 241, or else, latches the input address AD into a register 212 through a selector 262. When the input address AD is previously stored in the register 241, the address queue control circuit 19A latches the input address AD into the register 212 through the selector 262. After reading the contents of the register 211, the address queue control circuit 19A shifts the offset OFS of the register 241 to the offset field of the register 211 through a selector 261, and resets a valid flag EF of the register 241.

摘要： The present invention relates to a processor that performs a load operation prior to a store operation while avoiding ambiguous memory reference, and achieves high-speed operations. The present invention also relates to a method of controlling such a processor. This processor includes a history control unit that stores a storage destination of a result obtained by executing a second instruction that is executed prior to a first instruction placed before the second instruction. When it is determined that the address of first data to be processed by the first instruction is included in the address region of second data to be processed by the second instruction, the history control unit overwrites the result obtained by the execution of the first instruction on the second data corresponding to the address.
