Abstract:
PURPOSE: An apparatus and a method for complex number computation using a SIMD(Single Instruction Multiple Data) structure are provided to implement serial or parallel computation of real number and imaginary number parts of complex numbers. CONSTITUTION: Complex number computation units(120,150,180) implements first to third computation of first to fourth complex numbers. The first computation includes first to fourth parallel multiplication that multiplies every two of eight numbers, where the eight numbers are the rear number and imaginary number parts of the first to fourth complex numbers. The second computation calculates a first sum of the first and third multiplication and a second sum of the second and fourth multiplication. The third computation subtracts the second sum from the first sum or adds the second sum to the first sum.
Abstract:
PURPOSE: A material quality guarantee and process application system is provided to automatically perform acquisition inspection on the material for semiconductor devices, to manage a reliability of COA/ASMS(Certificate of Analysis/Advanced Supplier Management System) on the material, and to apply the quality data of the material to a producing process. CONSTITUTION: The system comprises a database(20) and a client program module(30). The database(20) includes a COA/ASMS database file(22), a bar code database file(24), and a specification database file(26), and a process database file(28). If a material supplier(70) transmits the COA/ASMS data to a web server(40) of a material demander, the system uploads the COS/ASMS data to the COA/ASMS database file(22) under a protocol of the FTP. The bar code database file(24) includes data on processes using a specific material for producing a semiconductor device, producing equipments or material input time. The process database file(28) stores data generated during a specific process. The client program module(30) includes an acquisition inspection module(32), a COA/ASMS analysis module(34), a material/process application analysis module(36) and a report module(38). The COA/ASMS analysis module(34) downloads data from the database files(22, 26), and analyzes statistically the COA/ASMS data. The material/process application analysis module(36) downloads data from all the database files(22, 24, 26, 28), assesses characteristics of the material, and optimizes the specifications of the material.
