Complexity and Performance Tradeoffs with FPGA Partial Reconfiguration Interfaces
Two different interfaces, namely the JTAG and SelectMAP interfaces, have been proposed for controlling and managing partial reconfiguration of SRAM-based Field Programmable Gate Arrays (FGPAs). Each of these interfaces provides distinct advantages in terms of area overhead and reconfiguration latency. In this paper, two corresponding sets of Application Programming Interfaces (APIs) are develop...
متن کاملA Novel Optimized JTAG Interface Circuit Design
This paper describes a novel optimized JTAG interface circuit between a JTAG controller and target IC. Being able to access JTAG using only one or two pins, this circuit does not change the original boundary scanning test frequency of target IC. Compared with the traditional JTAG interface which based on IEEE std. 1149.1, this reduced pin technology is more applicability in pin limited devices,...
متن کاملA Symbolic Debugger for Powerpc-based Hardware, Using the Engineering Support Processor (esp)
For debugging PowerPC-based hardware systems, there is a tool named the Engineering Support Processor (ESP) that accesses and controls the chip via the JTAG interface. With the ESP, a user can debug a target system by starting and stopping it, accessing registers and memory, and so on. However, with ESP alone, it is di cult to symbolically debug programs written in high-level languages such as ...
متن کاملAn Implementation of IEEE 1149.1 to Avoid Timing Violations and Other Practical In-Compliance Improvements
An implementation of the IEEE 1149.1 standard (JTAG) is presented in this paper. Rules are given for removing gated clocks, registering of all the TAP controller outputs, and daisy-chaining the boundary-scan cell clocks, resets, and control signals in a direction opposite to that of TDI to TDO signal. Several major advantages are obtained as a result of these implementation rules. Timing issues...
متن کاملDeclaratively Solving Google Code Jam Problems with Picat
In this paper we present several examples of solving algorithmic problems from the Google Code Jam programming contest with Picat programming language using declarative techniques: constraint logic programming and tabled logic programming. In some cases the use of Picat simplifies the implementation compared to conventional imperative programming languages, while in others it allows to directly...
