This paper presents the ZUMA open FPGA overlay architecture. It is an open-source, cross-compatible embedded FPGA architecture that is intended to overlay on top of an existing FPGA, in essence an ”FPGA-on-an-FPGA.” This approach has a number of benefits, including bitstream compatibility between different vendors and parts, compatibility with(More)
Overlay architectures are programmable logic systems that are compiled on top of a traditional FPGA. These architectures give designers flexibility, and have a number of benefits, such as being designed or optimized for specific application domains, making it easier or more efficient to implement solutions, being independent of platform, allowing the(More)
Overclocking a CPU is a common practice among home-built PC enthusiasts where the CPU is operated at a higher frequency than its speed rating. This practice is unsafe because timing errors cannot be detected by modern CPUs and they can be practically undetectable by the end user. Using a timing speculation technique such as Razor, it is possible to detect(More)
FPGAs are increasingly being used to implement many new applications, including pipelined processor designs. Designers often employ memories to communicate and pass data between these pipeline stages. However, one-cycle communication between sender and receiver is often required. To implement this read-immediately-after-write functionality, bypass registers(More)
