We have developed the back-end readout electronics (BEE) for Hyper Suprime-Cam (HSC). HSC is the next generation wide-field camera to be mounted on the 8.2-meter diameter Subaru Telescope in Hawaii. It employs 116 pieces of 2k × 4k Charge Coupled Devices (CCDs) to cover a 1.5 degrees diameter field of view. The electronics system for HSC can be divided into two parts: the front-end electronics (FEE)...
Transmission Control Protocol (TCP) and Ethernet have been widely used in readout systems. These protocols are de facto standards and have been implemented on standard operating systems. However, some small devices, e.g., front-end devices and detectors, are not capable of employing these protocols because of hardware size limitations. This paper describes a TCP processor for Gigabit Ethernet with...
