DEVICE AND METHOD FOR HARDWARE/SOFTWARE CO-EMULATOR FOR SUPPORTING MULTI FUNCTION MODULE

摘要

PURPOSE: A device and method for a hardware/software co-emulator is provided to validate and manufacture a prototype after manufacturing a design at low cost by emulating a software and a hardware at the same environment, changing and appending each function module necessary for a user easily, and making a library based on modules according to each filed and function. CONSTITUTION: A microprocessor unit(10) emulates a control signal for managing the total system and a portion designed by a software and processes information being transmitted at the interior and the exterior. A ROM(20) is existed in a memory bank, operates the micro processor unit(10), and loads a ROM BIOS for generating a control signal for controlling an external interface port using the micro processor unit(10). A RAM(30) is existed in the memory bank, supplies a memory space necessary for operating the microprocessor unit(10) and the ROM(20), and emulates a software design by downloading a software designed program using an external interface. A programmable IC chip(40) constructs logic and an I/O port necessary for the system in real time. Information in the system is transmitted to a necessary place through an address and data bus(50), a control bus(60), a serial port(70), and a parallel port(80). A top board standard I/O interface unit(90), an extension board programmable I/O interface unit(99), the serial port(70), and the parallel port(80) are operated by controlling an I/O terminal of the programmable IC chip(40), the address/data bus(50), and the control bus(60) by the micro processor unit(10) and a ROM BIOS program included in a system program at the ROM(20) in the memory bank.
