Gowin FIFO SC HS
IP Introduction
Gowin FIFO IP contains synchronous FIFO (FIFO SC HS) IP and
asynchronous FIFO (FIFO HS) IP.
- The read ports signals and write ports signals of the synchronous FIFO are all controlled by one clock domain;
- The read ports signals and write ports signals of the asynchronous FIFO are controlled by two independent clock domains.
The Gowin IP Core Generator can be used to generate a FIFO IP with single-cycle read/write and configurable ports. The configuration port is such that you can generate
FIFO SC HS IP Function and Feature
- The implementation type of the internal storage structure of FIFO SC HS IP is configurable, including block SRAM, Shadow SRAM and LUT;
- Write data depth is configurable. The depth is 2n, and the maximum value is 65536;
- Write data bit width is configurable. The size is 1-256 bit;
- The depth and bit-width of read/write data are equal;
- The output of the write data number is configurable. Users can choose whether to output the write number data;
- The flag signal output is optional. You can choose to output an almost-empty flag, an almost-full flag or no flag;
- If you choose to output an almost-empty or almost-full flag, the threshold of almost-empty, almost-full is configurable. They can be set as: Static single constant threshold, Static double constant threshold, Dynamic single input threshold, Dynamic double input threshold;
- The ECC check function is optional. The ECC check function can be selected when the FIFO SC HS storage structure is achieved by block SRAM and the read/write bit-width are equal and are all below than 64bit;
- The output register function is configurable. If you choose the output register function, the read-enable (RdEn) control is optional. If the user chooses enable-control, the output register is controlled by RdEn, and the last data cannot be output. If you choose the output register function instead of read-enable control, the read data output will be a cycle later, and the last data will be output.
- First-Word Fall-Through function is supported.
