Little Endian in Instruction

By -

I'm learning about RISC-V instructions in Computer Architecture. What i wonder is, because of little endian, any number in RISC-V's instruction's little digit is on little bit. I know that RISC-V use little endian to express data in memory. but I'm not sure it is same to express number in instructions.

for example, add instruction has that form, [funct7][rs2][rs1][funct3][rd][opcode], MSB is in funct7, LSB is in opcode. and rs1, rs2, rd is some number with 5bits. if [rd] is 0b00001, position of 1 is LSB in rd's 5 bits. this point is my question. is reason that 1's position is LSB, RISC-V use little endian? if that is right, is (0b00001's) position of 1, MSB in big endian?

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects". Re-usability is the main concept of Oops. There are few major principles of object-oriented paradigm.

Spring Boot and Vaadin : Filtering rows in Vaadin Grid

By -
Adding a text field for filtering: Start by adding a text field above the grid. Remember, MainView is a VerticalLayout, so you need to add the text field before the grid. MainView.java public class MainView extends VerticalLayout {   private ContactService contactService;   private Grid<Contact> grid = new Grid<>(Contact.class);   private TextField filterText = new TextField(); ①   public MainView(ContactService contactService) {   this.contactService = contactService;   addClassName("list-view");   setSizeFull();   configureFilter(); ②   configureGrid();   add(filterText, grid); ③   updateList();   }   private void configureFilter() {   filterText.setPlaceholder("Filter by name..."); ④   filterText.setClearButtonVisible(true); ⑤   filterText.setValueChangeMode(ValueChangeMode.LAZY); ⑥   filterText.addValueChangeListener(e -> updateList()); ⑦   }   // Grid...
