This paper describes a tree-based compression technique for word-oriented memories. The technique can speed up the transmission of diagnosis data from the embedded RAM with BISD support. By using a simplified Huffman coding scheme and partitioning each 256-bit Hamming syndrome into fixed-size symbols, the average compression ratio is reduced to about 10%, assuming 16-bit symbols. The proposed compression technique reduces the time for diagnostic test, as well as the tester storage requirement.","PeriodicalId":388391,"journal":{"name":"2001 International Symposium on VLSI Technology, Systems, and Applications.

{"title":"Homogeneous multiprocessing and the future of silicon design paradigms","authors":"P. Stravers, J. Hoogerbrugge","doi":"10.1109/VTSA.2001.934515","DOIUrl":"https://doi.org/10.1109/VTSA.2001.934515","url":null,"abstract":"This paper addresses two challenges of the consumer semiconductor industry: (1) economical and social forces are increasingly reducing the length of product life cycles, and (2) the continuing exponential growth of the on-chip transistor count is pushing design complexity. In concert these two trends represent a formidable challenge for semiconductor companies that aim to benefit from future technological developments in highly competitive markets. The paper derives a relation between on-chip memory real estate and compute logic, suggesting that homogeneous multiprocessors are an unavoidable consequence of the technology curve. A particular approach to homogeneous multiprocessing is then presented that combines scalability with high computational performance and with high power efficiency. We also present the implementation of a programming paradigm for homogeneous multiprocessors that focuses on reuse of tested and approved functions at the software level. This enables a shift from today's not-so-successful practice of hardware core reuse to the reuse of functions that have very well defined and uniform interfaces. The time frame for large scale commercial application of this type of homogeneous multiprocessor architecture is expected to coincide with the arrival of 0.07 micron technology for consumer products, i.e. 2006 and beyond. The paper concludes with a case study of an MPEG2 decoder and how a few simple guidelines can significantly increase the exposed concurrency of the application.","PeriodicalId":388391,"journal":{"name":"2001 International Symposium on VLSI Technology, Systems, and Applications.

This paper reports a manufacturable 0.18 /spl mu/m eDRAM technology, where this task has been successfully accomplished. The characteristics of logic and array devices operating from a power supply of 1.8 V are presented. The eDRAM logic device characteristics are compared with 'logic-only' (base) process devices and are found to be comparable. DRAM device characteristics, leakage and retention data measured on test structures are also shown which satisfy the temperature range of operation from 0/spl deg/C to 105/spl deg/C of the product.","PeriodicalId":388391,"journal":{"name":"2001 International Symposium on VLSI Technology, Systems, and Applications.
