Automatic addition of reset in asynchronous sequential control circuits

pre-printAsynchronous finite state machines (AFSMs) usually require initialization to place them in a desired starting state. This normally occurs by toggling a reset signal upon power-up. This paper presents an algorithm to automatically generate power-up reset circuitry thus adding reset to an AFSM after technology mapping. This approach is independent of design methodology since it is applied to a gate netlist. The algorithm ensures all combinational cycles and primary outputs in the circuit are initialized. Options exist in reset generation to minimize the power or performance impact on the AFSM. Results are reported for applying this algorithm to designs of varying size and complexity

Interfacing synchronous and asynchronous domains for open core protocol

pre-printIntellectual property (IP) blocks are connected in a system on chip using a bus or network-on-chip (NoC). IP reuse is facilitated by the modularity that results when using common interfaces between the IP cores and the bus or NoC. This paper investigates and implements several versions of one of the common interfaces, the open core protocol (OCP). The paper addresses two new aspects of interface design. First, an approach is developed to partition the common protocol portion of the interface from the interface back-end which is specific to the particular IP. This is achieved with a component we call a domain interface at this boundary. Second, the domain interface is enhanced to synchronize between IP blocks and busses that use different clock frequencies or asynchronous (unclocked) logic. As a result IP operating at unrelated frequency and fully asynchronous (unclocked) blocks can more easily be integrated into a system. Results are reported for power, performance and area for these clocked and asynchronous implementations

Differences In Management and Marketing Professors\u27 Perspectives On The Rising Cost of College Textbooks

Textbooks are an integral component of the higher education process. However, a great deal of concern about the high costs of college textbooks has been expressed by those inside and outside of higher education. This paper focuses on the results of a study of the differences in Management and Marketing professors\u27 criteria and use of textbooks and their reactions to some of the changes that have been implemented or may be implemented by universities, state legislatures, and publishers to combat these cost escalations. Findings suggest that management and marketing instructors, particularly those with years of experience, acknowledge the concerns their students have over high textbook prices. They are willing to have legislation enacted to force changes in the marketing of the textbooks by publishers, but they do not want university policies that (from their perspective) restrict their choices for texts. Nor are they in favor of possible publisher cost saving strategies that appear to add administrative burdens on faculty involved in the adoption process

STICKER SHOCK: MANAGEMENT PROFESSORS’PERSPECTIVES ON THE RISING COSTS OF COLLEGETEXTBOOKS

This study uses Internet survey methodology to target management instructors’ views on the cost of textbooks and the strategies that might be exercised by universities, publishers, and legislatures to control cost increases. From a random sample of 2,893 management professors selected, using university websites, from universities throughout the United States, 228 provided useable responses. Findings suggest that management instructors, particularly those with years of experience, acknowledge the concerns their students have over high textbook prices. They are willing to have legislation enacted to force changes in the marketing of the textbooks by publishers, but they do not want university policies that unduly (from their perspective) restrict their choices for texts. Nor are they in favor of possible publisher cost saving strategies that appear to add administrative burdens on faculty involved in the adoption process. Future research should include investigating techniques for reducing the rising costs of textbooks
