A modular system including a set of functionality tiles and a control tile storing a storage structure, an initialization file, and operation instructions. The method for operating a custom device made using the modular system includes: sending operation settings for each tile to the respective tile upon device initialization; operating each tile based on the operation settings; writing the output from each tile to the storage structure; monitoring data streams within the storage structure for a trigger event; reading data off the storage structure in response to occurrence of the trigger event; and processing the read data according to a processing function specified by the operation instructions.

A waveform generator includes a system control unit and signal channels controlled by the system control unit and configured to supply driving signals for driving a respective transducer of an array of transducers. Each signal channel includes a sequential access memory having rows, where each row contains an instruction word configured to generate a respective step of a waveform to be generated. A memory output of the sequential access memory is defined by an output row at a fixed location. The waveform to be generated is defined by a block of instruction words. Each signal channel also includes an internal control unit that is configured to sequentially move the content of the sequential access memory, based on the instruction word currently at the memory output, so that sequences of instruction words are provided at the output row.

Some embodiments of the present disclosure provide an associatively indexed circular buffer (ACB). The ACB may be viewed as a dynamically allocatable memory structure that offers in-order data access (say, first-in-first-out, or FIFO) or random order data access at a fixed, relatively low latency. The ACB includes a data store of non-contiguous storage. To manage the pushing of data to, and popping data from, the data store, the ACB includes a contiguous pointer generator, a content addressable memory (CAM) and a free pool.
