Abstract

The invention discloses SoC architecture with the high cost performance. The SoC architecture comprises an improved 8051 kernel, a flash kernel, an analog-digital converter, a real-time clock, a serial port, an SPI interface, a universal IO port, a communication transceiver, a data memory and an I2C interface; the analog-digital converter, the real-time clock, the serial port, the SPI interface, the universal IO port and the I2C interface are electrically connected with the 8051 kernel through an SFR bus or an xmem bus, the communication transceiver is electrically connected with the 8051 kernel through the SFR bus and the xmem bus, the data memory is electrically connected with the 8051 kernel through the xmem bus, the flash kernel is electrically connected with a flash access control circuit through a flash signal, and the flash access control circuit is electrically connected with the 8051 kernel through a read-write bus and supports program burning. According to the SoC architecture, the memory space can be saved, the speed can be increased, and a bank operation of the 8051 in the flash is supported; the improved 8051 kernel is adopted and is compatible with a standard 8051 instruction set, therefore, small chip area is occupied, the cost and the risk are reduced, the system design is simplified, and power dissipation and the cost are reduced.

Description

technical field [0001] The present invention relates to the technical field of chip architecture, in particular to a SoC device. Background technique [0002] Now many commercial chips are trying to increase the integration level as much as possible, so as to reduce costs and improve reliability. Often a chip is a small system on a chip (SoC). The CPU cores are generally used for data operations and / or transaction processing. High-performance CPU cores often require license fees and occupy a large chip area. In practical applications, it is often not necessary to blindly pursue high performance—for example, some applications do not have a large amount of data, or there are additional coprocessors to share part of the calculations. Under the premise of ensuring a certain performance, a simple CPU core and the corresponding system architecture can simplify system design, reduce power consumption and cost. In addition, rich applications are the main problem that embedded te...

In addition, rich applications are the main problem facing embedded terminals now, which means a large number of applications, that is, a large program space is required

The traditional 8051 program space addressing is only 64k, which is stretched in the face of the above applications
