Problems solved by technology

For the case where the destination address of the above access operation is a discrete address, it is necessary to send an operation request packet separately for each discrete address (similarly, ASIC also returns an operation reply packet each time), resulting in the data packet of the SRIO interface access operation The data load carried is small, so it directly restricts the efficiency of the SRIO interface and seriously affects the ut...

Abstract

The invention discloses a method and a device for accessing registers, belonging to the communication field. The method comprises the following steps: an access interface receives an accessing operation request packet sent by a processor; the accessing operation request packet carries the addresses of at least two registers to be accessed; the registers corresponding to the addresses are accessed according to the addresses carried in the accessing operation request packet. The device comprises a receiving module and an access module. When a DSP processor accesses an ASIC chip, through the set access interface, the invention realizes concentrated access to the registers and increases the useful data load in single accessing operation, thereby effectively improving the efficiency of the SRIO interface and utilization of the transmission bandwidth.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for accessing registers. Background technique [0002] SRIO (Serial Rapid Input Output, serial high-speed input and output) is an open interconnection protocol based on packet switching technology. , less pins, high reliability, long transmission distance, independent of the processor and other advantages, has been widely supported and applied. [0003] At present, in WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) system, see figure 1 , the baseband data processing of the base station NodeB is based on the SRIO interface, and is completed by a DSP (Digital Signal Processing, digital signal processing) processor in conjunction with a baseband processing ASIC (Application Specific Integrated Circuit, application specific integrated circuit) chip. The SRIO interface performs access operations on the ASIC chip. Among them, the ac...
