Abstract
The low cost of commercial-off-the-shelf static random access memory (SRAM) devices allows wide use in space applications. The proper functioning of microsatellites in orbit is ensured by data and instruction set (program) stored in these devices. The SRAM memory that operates in the space environment risks data corruption due to single-event upset (SEU) and single-event multiple-bit upset. Therefore error detection and correction (EDAC) based on shortened Hamming (12,8) code and quasi-cyclic (16,8) code are ordinarily used for protecting the SRAM against errors due to SEU. The proposed EDAC is based on the Single Error Correcting and Double Error Detecting Hsiao (72,64) code which is compared with the two previous EDACs in terms of the number of Field Programmable Gate Array that implements these codes, delay time for encoding/decoding operations, memory overhead, and error detection and correction capability.
期刊介绍：
Analog Integrated Circuits and Signal Processing is an archival peer reviewed journal dedicated to the design and application of analog, radio frequency (RF), and mixed signal integrated circuits (ICs) as well as signal processing circuits and systems. It features both new research results and tutorial views and reflects the large volume of cutting-edge research activity in the worldwide field today.
A partial list of topics includes analog and mixed signal interface circuits and systems; analog and RFIC design; data converters; active-RC, switched-capacitor, and continuous-time integrated filters; mixed analog/digital VLSI systems; wireless radio transceivers; clock and data recovery circuits; and high speed optoelectronic circuits and systems.
