Field-programmable gate array
Field-programmable gate array\
only for these students that are intrested in Field-programmable gate array
field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence "field-programmable". The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC). (Circuit diagrams were previously used to specify the configuration, as they were for ASICs
The FPGA industry sprouted from programmable read-only memory (PROM) and programmable logic devices (PLDs). PROMs and PLDs both had the option of being programmed in batches in a factory or in the field (field-programmable). However, programmable logic was hard-wired between logic gates.[6]
In the late 1980s, the Naval Surface Warfare Center funded an experiment proposed by Steve Casselman to develop a computer that would implement 600,000 reprogrammable gates. Casselman was successful and a patent related to the system was issued in 1992.[6]
Some of the industry's foundational concepts and technologies for programmable logic arrays, gates, and logic blocks are founded in patents awarded to David W. Page and LuVerne R. Peterson in 1985.

Microcontroladores: introducción a la programación en lenguaje ensamblador AVRSANTIAGO PABLO ALBERTO
The document discusses branching and conditional control transfer instructions in AVR assembly language. It explains how unconditional jump instructions like jmp and call directly set the program counter to a target address. Relative jump instructions like rjmp and rcall add a signed offset to the program counter. Conditional branch instructions like breq test status register flag bits and conditionally set the program counter by adding a signed offset if the test condition is true. The document provides examples of how these instructions work at the machine level to transfer program control flow.ASIC DESIGN FLOW
This document outlines the typical ASIC design flow process. It begins with specification where the features and functionalities of the ASIC are defined. This is followed by RTL coding to develop the logic functionality in a hardware description language. Simulation and synthesis then convert the RTL into a gate-level netlist. Pre-layout timing analysis checks for timing issues. Then automatic place and route lays out the design on the chip. Back annotation adds layout parasitic information. Post-layout timing analysis checks for real timing violations. Logic verification confirms correct functionality. The final tapeout step sends the design for fabrication if all checks pass.
Instruction Pipelining
This document discusses instruction pipelining and various techniques used to handle hazards that can occur in pipelined processors. It describes a 6-stage instruction pipeline consisting of fetch, decode, calculate operands, fetch operands, execute, and write-back stages. There are three main types of hazards: resource hazards which occur when instructions need the same processor resource; data hazards which occur when an instruction uses a value not yet ready from a previous instruction; and control hazards which occur when the program flow changes due to a branch. Solutions to handle these hazards include branch prediction, delayed branching, pipeline stalls, and maintaining multiple instruction streams.
Chapter 04 the processor
The document discusses pipelining in computer processors. It explains that pipelining allows for overlapping execution of multiple instructions to improve processor throughput. An analogy is drawn to an assembly line in laundry - non-pipelined execution is like completing an entire load sequentially, while pipelined is like having different stages of multiple loads occurring in parallel. Pipelining is achieved by breaking instruction execution into discrete stages, such as fetch, decode, execute, memory, and writeback. This allows new instructions to enter the pipeline before previous ones have finished, improving instruction completion rate.
Design of embedded systems
The document discusses hardware/software co-design of embedded systems. It describes how embedded systems use computers for dedicated functions and discusses issues in designing these systems, including hardware/software partitioning and allocation.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
