Method for creating parallel processing system

Abstract

A definition file included in the present invention includes a plurality of parallel descriptions that respectively define a plurality of parallel processes performed independently. The plurality of parallel descriptions include a first parallel description showing a first parallel process with a plurality of data inputs including at least one data input into which output data of another parallel process is inputted, with data with the same latency from input in a parallel processing system are inputted into the plurality of data inputs. A forming method includes a first step of generating, based on a hardware library in which information on a plurality of types of elements is stored, hardware configuration information including circuit configurations for executing the parallel processes that include at least one of the plurality of types of elements; and a second step of adding a delay element to the hardware configuration information so that data with a same latency from input into the parallel processing system are inputted into the plurality of data inputs of the circuit configuration for executing the first parallel process, and therefore the hardware configuration information is generated by this method.

Description

TECHNICAL FIELD [0001] The present invention relates to designing a parallel processing system and in particular to a method and apparatus that generate hardware configuration information for a parallel processing system based on a definition file and to a method of simulating a parallel processing system based on a definition file. BACKGROUND ART [0002] A number of types of languages are used when designing LSIs and ASICs. High-level languages such as “C” that have a high degree of abstraction are languages on a procedural level and are suited to showing how an entire process is executed in order on an instruction-by-instruction basis. Description on this level normally has no hardware dependency, is composed of application pro grams that can be received by a suitable computer, and is normally used to describe the specification of an LSI or an entire process executed by an LSI. Hardware description languages (HDL) such as Verilog-HDL or VHDL are also referred to as RTL and are used...

Benefits of technology

[0023] Forming a parallel processing system according to the definition file may include a variety of optimizations. When the plurality of parallel descriptions include a second parallel description that defines a second parallel process including shared processing that is common to at least part of a third parallel process defined by a third parallel description, in the first step, a shared circuit configuration including at least one of the plurality of types of elements can be generated for the shared processing, and, in such case, in the second step, a delay element is added to a circuit configuration for executing a difference between the second parallel process and the shared processing as the circuit configuration for executing the first parallel process. The circuit configuration for executing the difference between the second parallel process and the shared processing usually becomes a configuration with a plurality of data inp
