Title:
BLOCK MEMORY CONFIGURATION STRUCTURE AND CONFIGURATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/082141
Kind Code:
A1
Abstract:
A block memory configuration structure and configuration method, the block memory configuration structure comprising: a first port, a second port, an ECC module, an FIFO module; the first port has write width and read width of different values; the second port has write width and read width of different values; the read width in the first port and the read width in the second port are of different values; the write width in the first port and the write width in the second port are of different values; the ECC module comprises an ECC encoder and an ECC decoder; the FIFO module is used for setting an enable terminal of a first clock and the enable terminal of a second clock to synchronize a read clock and a write clock of the block memory or enable asynchronization between the read clock and the write clock of the block memory. The block memory configuration structure and method enable the read width and the write width of the block memory to be configured independently; the block memory is internally provided with an ECC function and an FIFO function, and eliminates the need of extra logical resource consumption when being cascaded into a block memory having a larger storage space.
