In this paper we have presented an efficient FPGA implementation of a reciprocator for both IEEE single-precision and double-precision floating point numbers. The method is based on the use of look-up tables and partial block multipliers. Compared with previously reported work, the modules occupy less area with a higher performance and less latency. The designs trade off either 1 unit in last-place...
An efficient architecture for implementation of double precision floating point multiplication on field programmable gate array (FPGA) is presented, based on the use of partial block multipliers. The proposed module gives excellent performance with efficient use of resources, achieving upto 292 MHz on a Xilinx Virtex II Pro device and 325 MHz on a Xilinx Virtex IV. The cost of the design is an error...
Debugging memory test failures in a system-on-chip design is becoming difficult due to the growing number and sizes of the embedded memories. Low-complexity marching tests, which are ideally suited for production testing, are insufficient for debug and diagnostics. On-chip support for multiple memory test algorithms can be prohibitively expensive. Moreover, memory test engineers would like the flexibility...
In this paper, we propose a way to improve the yield of memory products by selecting the appropriate test strategy for memory Built- in Self-Test (BIST). We argue that by testing the memory through a sequence of test algorithms which differ in their fault coverage, it is possible to bin the memory into multiple yield bins and increase the yield and product revenue. Further, the test strategy must...
An algorithm and architecture for a hardware based simulation accelerator is presented. The accelerator can perform full timing simulation of synchronous digital circuits described at the gate level. The simulator makes use of a cycle based processor core in conjunction with event queues to execute the simulation. By ensuring that the gates are evaluated in rank order, the problem of sorting event...
