The invention relates to a reconfigurable a 8-bit RSIC (reduced instruction set computer) SCM (Single Chip Microcomputer) simulator which comprises a simulation monitoring chip, a simulation chip and a memorizer; the simulation monitoring chip is communicated with an upper computer through a USB interface; the upper computer can update simulation firmware in the simulation monitoring chip conveniently through the USB interface, automatically configure the simulation chip into a target SCM required by a user and download user codes into a memorizer through the simulation monitoring chip; the simulation chip reads the user codes in the memorizer and executes the codes; the simulation monitoring chip can receive all recommends of the upper computer through the USB interface at any time so as to control the simulation of the simulation chip and feed back various states of the simulator to the upper computer at any time. According to the reconfigurable simulator, as the simulation firmware in the simulation monitoring chip is updated and the simulation chip is configured into inner cores of different SCMs, so as to construct different SCM simulators through the software approach, the simulation development of RSIC SCMs from in different series is realized and the operation is convenient.
Description
Technical field [0001] The invention relates to a simulator, in particular to a reconfigurable 8-bit RISC single-chip microcomputer simulator, which belongs to the technical field of electronic control devices. Background technique [0002] Currently, 8-bit RISC architecture microcontrollers (MCUs) are widely used in smart devices, especially household appliances, smart tools, smart toys, medical care, security systems, power management, etc. The market demand is huge. The huge market demand has attracted many microelectronics manufacturers to develop a wide range of 8-bit RISC microcontrollers, most of which are general-purpose microcontrollers, and some are dedicated or semi-specialized. In this hot land, famous manufacturers such as PIC, EMC, Holtech, Sonix, Feeling, etc. have gathered. [0003] General-purpose single-chip microcomputers usually need to undergo secondary development according to actual application requirements to meet actual application requirements. The focus...
