Abstract

An embedded system includes an ARM processor and a number of b-bit peripheral processors connected to the ARM processor through a converting chip. The ARM processor includes pins P0~Pa-1 divided into teams T1~TN, each of which includes b pins, a and b are integral multiple of 8, wherein a=N×b. The number of the peripheral processors is N and each team corresponds to one peripheral processor. The converting chip reads an a-bit data from the ARM processor, converts the data into a plurality of b-bit data, and transfers each b-bit data to a peripheral processor, where the number of the b-bit data is N. The converting chip further reads one b-bit data from each peripheral processor in sequence, converts the read plurality of b-bit data into an a-bit data, and transfers the a-bit data to the ARM processor.

Description

technical field [0001] The invention relates to an embedded system. Background technique [0002] With the rapid development of semiconductor technology, the processing capability of ARM (Advanced RISC Machines, a general name for a type of microprocessor) processor is getting stronger and stronger, but because the product requires complete functions, the realization of these functions only relies on ARM processing The on-chip resources of the processor cannot be satisfied, and a certain peripheral processor is required, so the embedded system based on the ARM processor is more and more widely used, and the embedded products have been widely distributed in military, consumer electronics, communication, industrial control, etc. field. [0003] Such as figure 1 As shown, it is a schematic diagram of a traditional connection mode between the peripheral processor of the embedded system 1000 and the ARM processor in an electronic device. In this figure, an embedded system 1000...
