Loading of data in multiple programmable devices uses devices coupled in parallel

摘要

A number of field programmable analogue, FPAA, devices [22,24,26] are coupled to a parallel data bus [28] over data input pins ,DIN. A clock connects to all devices [36] and they also have enable inputs [37-39]. Outputs of one device connect with the enable input of the next device. Data is inputted over the data bus.
