摘要:
A reconfigurable processor calculates execution times of configuration for executing pipeline processing from hardware configuration information, and fixes a clock cycle until processing ends. A counter compares the fixed clock cycle with the actual number of elapsed clocks, and, when the number of elapsed clocks equals the clock cycle, it is determined that pipeline processing has ended, and a configuration controller is notified of this.

A reconfigurable operation apparatus consists of a plurality of operation units capable of reconfiguring themselves by using a piece of given first configuration data and of operating simultaneously with one another; RAMs; diverse processor elements required for constituting an operation apparatus; an inter-resource network interconnecting the operation units, the RAMs and the diverse processor elements, performing data transfers between resources connected thereto in a uniform transfer time independent of positions and kinds of the resources, and being reconfigurable by using a given second configuration data; and a configuration memory storing the first and the second configuration data. Configuration data is loaded from an external storage apparatus onto the configuration memory, and the first and the second configuration data are supplied to the reconfigurable processor resources in appropriate sequence and timing based on data available from a plurality of operation units.

A semiconductor device includes a plurality of memories, a sequencer which outputs configuration information, and a memory reconfiguring circuit which reconfigures the memory area in accordance with the configuration information supplied from the sequencer. Since the memory reconfiguring circuit dynamically changes the allocation of the memories, it is possible to reconfigure the memory configuration and freely change the memory size in accordance with the purpose of use.
摘要:
A semiconductor device includes a configuration memory for storing configuration data, an arithmetic unit whose circuit configuration can be reconfigured in accordance with the configuration data, and a fixed value memory for storing fixed value data to be supplied to the arithmetic unit. Since the configuration data and fixed value data to be supplied to the arithmetic unit are stored in the different memories, no data area for storing the fixed value data need be set in the configuration memory. This makes it possible to supply a predetermined fixed value to the arithmetic unit by storing only information for reading out fixed value data from the fixed value memory.
