System designers have long used FIFO memories to couple subsystems with disparate data-transfer rates. Recently, new types of these devices–with new capabilities–have emerged. Know your FIFO choices ...

Interfaces to digital data recorders often require deep FIFO buffers to match the system's data rate to the recorder rate. Sometimes, a second set of FIFO buffers in the opposite direction handles ...

FIFO (First In First Out) is a buffer that stores data in a way that data stored first comes out of the buffer first. Asynchronous FIFO is most widely used in the System-on-Chip (SoC) designs for data ...

Raspberry Pi’s microcontroller, the RP2040, has some unusual features. And one of these is the i-o state machine, of which there are eight. spread over two ‘PIO blocks’ – (one shown right). According ...
