Nowadays, with the development of large-scale integrated circuit design toward high integration, miniaturization and high speed, high performance SoC/ASIC chips require high efficiency and high reliability for accessing the on-chip memory space, and thus this also puts higher design requirements on the access control system of the memory space.
In general, an access control mechanism of a storage system is designed to convert an access command of a main device interface into an access command of a memory, and in this process, the main device interface generally gives an address, a chip select and an enable signal of a space to be accessed, so as to realize access of an on-chip memory space. Obviously, this approach requires the master interface to explicitly know the absolute address of the space to be accessed. If there is a host interface where there is no explicit absolute address space in the access command, only some relative access space variables such as numbers, offsets, etc. are given, which may be mapped to registers or buffers in the system where the space addresses to be accessed are stored, then efficient access to the memory space is not available by conventional methods.
The above-mentioned relative address plus absolute address access modes have been introduced in more and more high performance integrated circuit designs. This mode is similar to the "look-up table" mode of operation, and allows for fast and efficient access to space. Therefore, it is necessary to design a control system that can perform a query, complete an offset address index analysis, perform an absolute address calculation, and perform a memory space access.

and accessing the storage space according to the control signal in a read-write mode.
Specifically, in order to simplify the interface of the main device, the requirement of quickly searching and accessing the storage space through the relative space number can be met, and unlike the traditional mode of directly accessing the storage space by means of an address, the method and the system mainly relate to the following contents:
referring to fig. 1, the method of the present invention provides a new access flow, which can be divided into five units S0, S1, S2, S3, and S4. S0 is an access initiating unit, identifies the access of a main equipment interface, generates a request number and an access signal, and initiates an access request to S1 level; s1 is a matching query unit, which receives an access request, performs matching query on a query register set through a number in the access request, obtains a register corresponding to the number matched with the access request, and obtains a matching number stored in the register; s2 is an index selection unit, corresponding index numbers are obtained according to the matching numbers obtained in the S1, and offset addresses are extracted from the head domains corresponding to the storage space through indexing; s3, a storage access control unit calculates an access address of a storage space through an offset address, and generates a control signal required by read-write access of the storage space; s4 is an on-chip memory space unit, and the memory space of the memory entity is divided into two functional areas of a virtual header area and a data area.
Referring to fig. 2, a set of matching inquiry and read-write access control system is invented for the access flow of the method. The system is divided into two mechanisms, namely matching query control and data access control. The matching inquiry control mechanism can be divided into three subunits of inquiry register group, matching filtering and index selection. The query register set unit can realize the query of 3×n register sets, taking 3×n registers as query register sets as an example, and the register sets can be reduced according to the query feature requirement in specific application, so as to realize an m×n query register set, and the m×n query register set and the matched filtering unit together complete the identification hit of the effective number i. The Index selection unit indexes the corresponding Index number register through the hit effective number i to obtain an effective Index (i) number, the matching inquiry control function is completed so far, and the effective Index (i) number is sent to the data access control mechanism.
The data access control mechanism can be divided into three subunits of storage area access control, data cache and storage space. The memory space is divided into n sets of header fields and data fields, the header fields storing mainly data offsets corresponding to the data fields, which offsets are also called relative offsets. And the storage area access control unit acquires the data offset from the storage space area according to the effective Index number Index (i), completes the analysis of the relative offset and the calculation of the absolute address of the data area, and generates a RAM read-write access control signal to realize the access to the RAM area. The data storage unit is organically coordinated with the storage area access control unit to realize the caching of read-write data and the arrangement of data formats.
Referring to fig. 3, for the implementation of the inventive control system, a set of control jump state machines is designed, and matching inquiry and read-write access control state machines are provided. The jump state machine is divided into 7 states of Idle, filter_value, search_Index, search_Header, reg_Data, write_RAM, and read_RAM. The working mechanism of the whole state machine is as follows, the initiation of an access command is monitored under the Idle state, the access command is effective when coming, the operation jumps to the filter_value state for matching inquiry, after matching hit, the operation jumps to the search_index state for Index number inquiry, after Index inquiry is completed, the operation enters the search_header state for Header domain analysis, and the address offset in the Header domain is extracted. At this time, if the Write access is performed, the state of skipping to the reg_data is obtained from the cache, the absolute address of the Data field is calculated according to the base address and the offset address of the storage space, and then the state of skipping to the write_ram is performed to generate the chip select and Write enable signals of the storage space access to complete the Data writing; if the Read access is the Read access, the Read-RAM state is skipped to generate a chip selection and Read enabling signal of the RAM access, the absolute address of the Data domain is calculated according to the base address and the offset address of the storage space, the Data reading is completed, and finally the Read Data is sent into the Data cache after the Read-Data state is skipped.
According to the flow operation in (1), the inquiry register group in (2) is adjusted, inquiry information is changed according to the requirement, meanwhile, the space of the storage space is reasonably divided, the sizes of a header field and a data field can be adjusted, and the transplanting of the invention can be flexibly realized through the state machine jump in (3).
Fig. 1 shows the access flow of the present invention. Includes five parts, S0-Access initiation: the initiation of a read-write access request is realized; s1-matching query: matching numbers in the access request, inquiring the related register group, and generating a matching result after hit; s2, index selection: indexing to a corresponding index register according to the matching result generated in the step S1, acquiring an index number, and extracting an offset address of a header field; s3-storage access control: generating a control signal required by the read-write access of the storage space; s4, in-chip storage space: the target storage space to be accessed.

The matching inquiry control is divided into three subunits of inquiry register group, matching filtering and Index selection, so that inquiry of m multiplied by n register groups can be realized, inquiry of the effective Index number Index (i) is completed, and inquiry results are sent to the data access control unit. The data access control is divided into three subunits of storage area access control, data cache and storage space, index (i) number is coded according to the effective Index, index address analysis and absolute address calculation are completed, RAM read-write access control signals are generated, data cache is coordinated organically, and finally access to the entity storage space is achieved.
Monitoring the initiation of an access command in an Idle state, wherein the access command is effective when coming, jumping to a filter_value state to wait for a matching query result, jumping to a search_index state after matching hit, performing Index number query, entering the search_header state after Index query is completed, performing Header domain analysis, and extracting the address offset in the Header domain. At this time, if the Write access is performed, the state of skipping to the reg_data is obtained from the cache, the absolute address of the Data field is calculated according to the base address and the offset address of the storage space, and then the state of skipping to the write_ram is performed to generate the chip select and Write enable signals of the storage space access to complete the Data writing; if the Read access is the Read access, the Read-RAM state is skipped to generate a chip selection and Read enabling signal of the RAM access, the absolute address of the Data domain is calculated according to the base address and the offset address of the storage space, the Data reading is completed, and finally the Read Data is sent into the Data cache after the Read-Data state is skipped.
The invention is successfully applied to a vehicle-mounted FlexRay bus control circuit compatible with the FlexRay 2.1A protocol and a high-performance FlexRay MCU circuit developed based on the requirements of domestic tanks. By adopting a mode that a single host and a double hardware interface access the 8K capacity 16-bit dual-port RAM independently, the invention designs the structure, the access process only transmits the relative address space number, and after the inquiry hits, the offset address in the special space is indexed, thereby realizing the rapid and efficient access to the storage space, simplifying the host access interface and reducing the design complexity. The loading test is realized by both circuits, and the performance function meets the use requirement.
Finally, it should be noted that: the above examples are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, but it should be understood by those skilled in the art that the present invention is not limited thereto, and that the present invention is described in detail with reference to the foregoing examples: any person skilled in the art may modify or easily conceive of the technical solution described in the foregoing embodiments, or perform equivalent substitution of some of the technical features, while remaining within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention, and are intended to be included in the scope of the present invention.
