Abstract

The invention discloses a 8051 serial microprocessor application system based on the AMBA bus, which comprises the following steps: (1) setting second bridge to proceed transmission between microprocessor bus and APB bus, wherein the second bridge contains register group, logical selection mode, transmission stator and transmission logical controller; (2) setting a multipath selector of one in two interview APB bus among APB bus and first bridge and second bridge; (3) adding APB bus interface on the articulated mode of AHB bus; (4) displaying the following microprocessor address mapping program: a) allocating part of external data access space to the APB system; b) expanding the external data access space and APB address space through the register group in the second bridge; c) setting individual address space of AHB system and APB system through synthetic parameter logical.

Description

technical field [0001] The invention relates to an 8-bit microprocessor application system based on a 32-bit AMBA bus, in particular to an 8051 series microprocessor application system based on the AMBA bus. Background technique [0002] Generally, the layered technology of the bus is used in the design of the system chip SOC to better connect various modules with different characteristics to the bus. The on-chip bus (on-chip bus) is the interconnection structure of the SOC integrated system, which is generally divided into system bus (system bus) and peripheral bus (peripheral bus) two parts. The system bus can be considered as the hub connecting the processor core and the system modules. It is responsible for the initialization of the main system, data transmission between the main systems and other modules of the system, and requires bus arbitration to control multiple request signals. The slave system only responds to data requests. Peripheral buses often provide low-b...
