Why do some pc program counters increase by 8 and some increase by 4? did not understand
1. The PC stores the memory address to be accessed next. The specific increment is related to the instruction size and addressing method. For a 32-bit CPU, it is addressed by bytes, and the size of one instruction is 32 bits, which is equal to 4 bytes, so the next address is PC+4. Similarly, if the CPU is 64 bits, the size of one instruction is 64bit = 8 Byte, which is PC+8.
2. For example, if the current instruction occupies 1 byte, the PC value is increased by 1; if it occupies 4 bytes, the PC value is increased by 4. This process ensures the continuity of most sequential execution instructions.
3. The value of PC will automatically increase by the number of bytes of the current instruction. For example, if an instruction occupies 4 bytes, the PC value is incremented by 4 to point to the next instruction address.
4. Control and coordinate the various components of the computer to work in an orderly manner to complete the operations specified in the instructions. The content of the program counter (PC) is the address of the next instruction. When the program is executed sequentially, each time an instruction is fetched, the PC content automatically increases a value to point to the next instruction to be fetched. When a program branches, the branch address is sent to the PC, and then the PC points out the new instruction address.
5. In the principle of computer composition, PC refers to the Program Counter, which is an important register in the computer used to store the address of the instruction currently being executed (that is, the address of the next instruction to be executed). The core function of the PC is to automatically track the instruction execution process.
What is the difference between the three major mobile mainstream cup processors ARM/Intel/MIPS
The primary difference between ARM and Intel processors is that ARM uses the Reduced Instruction Set (RISC), while Intel uses the Complex Instruction Set (CISC). In short, reduced instruction sets are closer to atomic operations, while complex instruction sets are more complex. This makes the decoder for ARM processors simpler and helps achieve high efficiency and low power consumption. In terms of manufacturing processes, ARM and Intel processors use advanced technology.
The so-called CPU is actually a script that executes a series of instructions to drive computer equipment, including display screens, touch screens, modulators, etc. Currently, the CPU categories on the market are mainly divided into two camps, one is the complex instruction set CPU led by Intel and AMD, and the other is the reduced instruction set CPU led by IBM and ARM.
Different voltages: Notebook CPU: Notebooks are mainly portable, so most notebook CPUs are low-voltage.
Instruction set. In contrast, INTEL's processor is slightly better than AMD's in terms of multimedia instructions, and many software is optimized for SSE. Therefore, in multimedia software and flat processing software, compared with AMD processors of the same grade, INTEL's CPU appears to be more advantageous.
Divided according to CPU structure: single core, dual core, quad-core, eight-core, etc. Divided by processor technology development: Celeron, Core i series (i3, i5, or i7), etc. Divided according to the maximum CPU frequency: low-end, mid-end, and high-end.
What are the four development stages of computers?
1. The development of computers has gone through four stages: The first stage: the first generation of electronic computers (tube computers) The first generation of electronic computers was from 1946 to 1958. They are large in size, low in computing speed, small in storage capacity, expensive and inconvenient to use. This generation of computers was mainly used for scientific computing, and at that time it was only used in important departments or scientific research departments.
2. From the birth of the first computer in 1999 to the present, the development of computers has roughly gone through four stages according to the electronic devices used in computers. Namely: the first generation, tube computers with tubes as the main component (1946 - 1958); tubes are the basic electronic devices; they use machine language and assembly language; they are mainly used in national defense and scientific computing; their operating speed is several thousand times per second to tens of thousands of times.
3. The development and evolution history of calculators can be divided into four stages: mechanical calculators, electronic calculators, the popularization of personal computers and the decline of calculators, and the rise of mobile calculators. Mechanical calculator stage (late 17th century to 19th century) From the late 17th century to the early 18th century, calculators were purely mechanical structures at their core.
4.[Answer]: C divides the development of computers into four stages based on the main physical devices used by computers: the first generation (1946 - 1957) tube era; the second generation (1958 - 1964) transistor era; the third generation (1965 - 1970) medium-and small-scale integrated circuits era; and the fourth generation (1971-present) large-and ultra-large-scale integrated circuits era.
X86, ARM, RISC-V,MIPS are silly and unclear? One article will take you to understand!
In the world of chip design, X8ARM, RISC-V and MIPS are the four mainstream chip architectures. They each have unique characteristics and application areas, and these four architectures will be analyzed in detail below. X86 Architecture X86 is a computer language instruction set executed by a microprocessor that identifies a common set of computer instructions. This architecture originated from the 16-bit microprocessor 8086 released by Intel in 1978 and has continued to evolve with the development of CPU technology.
MIPS architecture is a classic reduced instruction set (RISC) architecture proposed by Stanford University in 1981, emphasizing simple instructions, fixed length and efficient pipeline design;RISC-V architecture is an open source instruction set architecture introduced in 2010, characterized by modularity, scalability and rapid ecological development.
IBM Power: With its high reliability and vertical integration capabilities, it occupies an important position in key areas such as financial core systems. New generations such as the Power10 further improve performance and energy efficiency. RISC-V: As an emerging architecture for open source customization, RISC-V shows great potential in areas such as IoT and edge computing. Xuantie 910 and other products have achieved remarkable results in the smart meter market.
Applications: Representatives of reduced instruction set architectures include ARM, RISC-V and MIPS.
In just a few years, RISC-V not only has policy support, but also has increased attention from enterprises and academic circles to this open source instruction set, and even Arm feels pressure.
RISC-V is an open instruction set architecture (ISA) based on the principles of reduced instruction set computing (RISC). It was developed by the Berkeley research team in the United States and aims to meet diverse computing needs through modularity, simplicity and open source features. Origin and background Start the engine: In 2010, the Berkeley research team decided to design a new instruction set due to licensing limitations and high cost of mainstream instruction sets (such as x8ARM).
Why does the 32-bit cpu instruction address increase with the minimum unit of 4?
1. This is what a bit machine is like. The data it processes at a time is 32 bits and 4 bytes. The computer stores it in bytes, and one byte is an address. Therefore, when a 32-bit machine reads and writes at a time, it is necessary to start with a certain integer address and operate on the 4 storage addresses in sequence. Remember: The computer stores it in bytes, one address per byte.
2. The pointer variable only occupies 4 bytes in the 32-bit C language. The reason why the number of address buses of the 32-bit CPU is 32, the memory space that can be addressed is 4GB, and each address occupies one byte, so it is necessary to use 4 bytes of pointer variables to store these addresses. The specific reasons are as follows: CPU addressing ability: A 32-bit CPU has 32 address buses, which means that the memory space it can address is 2^32 bytes, or 4GB.
3. Therefore, the pointer variable occupies 4 bytes in bit 32 and 8 bytes in bit 64. Of course, it may occupy 4 bytes in bit 64, which is also related to the compiler. Also, it cannot be said that an address occupies 4 bytes, and an address only occupies 1 byte. It can only be said that the data type occupies a few bytes. For example, integer int i = 9, we say that integer occupies 4 bytes, and the address of this integer variable is the address of the first byte of these four bytes.
4. Addressing space: Addressing space generally refers to the CPU's ability to address memory. The maximum range of addresses the CPU can find is called addressing ability. The addressing ability of the CPU is in bytes (bytes are the smallest addressable unit). For example, a 32-bit addressing CPU can address 2 to the 32nd power. The address is also 4G, which is why a 32-bit addressing CPU can be matched with a maximum of 4G memory. No matter how much, the CPU cannot be found.
5.^32 = 4 * 2^10 * 2 ^10 * 2^10B=4GB 32-bit X86 architecture means that the address bus of a personal computer is 32-bit, and the CPU, memory controller, and operating system are all designed according to the 32-bit address bus. The memory address code that can be supported by the 32-bit address bus is 4096MB, which means there is a 4GB address code and 4GB addresses can be programmed. This 4GB address code can be allocated to 4GB of memory.
6. Address bus width and addressing capabilities: The address bus width of a 32-bit computer is 32 bits, which means that it can represent 2 to the 32nd power of different memory addresses. In binary, 2 to the 32nd power equals 4, 294, 967, 296, and this number represents the number of memory addresses that a computer can address. Conversion between memory address and memory capacity: 1 byte (Byte) is equal to 8 bits (Bits), which is the basic unit of computer data storage.
