Title:
PROGRAMMABLE DEVICE STRUCTURE BASED ON MIXED FUNCTION STORAGE UNIT
Document Type and Number:
WIPO Patent Application WO/2019/114069
Kind Code:
A1
Abstract:
A programmable device structure based on a mixed function storage unit, comprising a storage unit SRAM and a mixed function unit, wherein the storage unit comprises n register units and at least one selection control bit, wherein n is equal to 2^x, and x is a natural number; the register units are selected according to the selection control bit, and a logic function is achieved when the selection control bit selects the mixed function unit to be used as a lookup table; or when the selection control bit selects the mixed function unit to be used as a multiplexer, a routing function is achieved. By multiplexing the register units, the programmable device structure achieves a routing function of a traditional FPGA, and also provides a logic function, and the waste of resources is greatly reduced.
