Abstract

The invention discloses a write path selection and control circuit for a configurable bit-width RAM. The circuit comprises: a bit-width configuration decoding circuit, an address enabling decoding circuit, an address sampling circuit, an address jumping circuit, a path Selection control circuit and write path selection circuit. A configurable circuit design is used to control the bit width of the write path, that is, the bit width of the write path of the RAM can be determined according to the configuration signal. In this way, RAM can be more conveniently used in configurable devices such as FPGAs. The maximum number of bits of the configurable bit width of the writing path of the present invention can reach 32 bits, which expands the practical scope of the RAM and enables the RAM to have the function of writing data quickly.

Description

technical field [0001] The invention relates to the field of circuit design, in particular to a write path selection and control circuit for configurable bit width RAM. Background technique [0002] As we all know, due to the advantages of user programmability and low development cost, Field Programmable Gate Array (FPGA) has become an important technology to realize modern circuits and systems and is widely used, and RAM is an important integrated resource in FPGA. The program data used is stored in it, and the data needs to be read from RAM during the working process. The existing RAM is a RAM with a fixed bit width, which leads to a small practical range of the RAM, and data must be written in the corresponding bit width, which not only affects the speed of writing data in the RAM, but also limits the range of use of the RAM. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a write path selection and contro...
