classroom at night and came back to lie down for a while at a.m. In the past year, the most widely used project is Web, which is too many to be described as quantity. The most valuable project is a project of the ZF department. Using EJB + sebservice involves bank interfaces, such as transfers. The biggest financial project is a 4 W project, an online examination system. I don't want to make too many comments on these lightweight and heavyweight technologies.

memory, the composition can be divided into three parts: 1. The arithmetic logic component Alu (arithmetic logic unit) is used for arithmetic and logical operations. This part has little to do with us, so we don't have to worry about it. 2. control logic. It has little to do with us. 3. This is the most important thing. The working Register plays an important role in the computer. Each register is equivalent to a storage unit in the memory, but its a

It indicates ACC overflow in the arithmetic operation of the number of symbols. Let's talk about overflow later. (6) P: parity bit: it is used to represent the parity of the number of binary digits "1" in the ALU operation result. If it is an odd number, P = 1, otherwise it is 0. F

Pixel shader // 32 pS threads are a group, and each (one of 32) is responsible for one fragment. Fragment requires 2x2 quad for processing. Each thread can process data from up to four triangles. Therefore, there will be a lot of waste: for example, the triangle generation is less than 8 pixels. This feature always works on all N cards. // When the size of a triangle is smaller than one pixel, the bounding box test will be performed. The bounding box is the BB of the triangle, and the test will

while modern processors have multiple cores.A core consists of an ALU, CU, and a set of registers.A core consists of two levels of caches called L1 and L2 which is there in each core.A processor consists of a cache that is shared by call cores called L3 cache. It is common to all cores.A processor depending on the architecture can consist of a memory controller and an input/output controller.Certain processor packages consist of Graphics Processing U

networks, K = 10 ^ 3, M = 10 ^ 6, G = 10 ^ 9, T = 10 ^ 12. My understanding is: 1 MB = 10 ^ 6 bytes, 512 ≈ 5 × 10 ^ 2000 ^ 6/(5 × 10 ^ 2) =.Summary of last week's exam errors P261 in the book: Logical Circuits can be designed to execute many different types of operations on word-level data. Arithmetic/logical unit (ALU) is a very important combination circuit. P262: in order to generate a time series circuit, that is, a stateful system that perfo

CPU functions: Basic CPU components: CPU = memory + controller + Cache Generator = Alu (arithmetic logic unit) + accumulators + latches Controller = program counter + instruction register + data buffer + address register + general register + State Register + time series generator + instruction decoder + bus (data path) Command cycle: the period of value, the time required to analyze the command, and the time required to execute the comm

C Two-dimensional array (pointer) Dynamic Allocation and release first clarify the concept: The 32-bit processor can only process 32-bit data at a time, that is, 4 bytes of data. The 64-bit processor can process 64-bit data at a time, that is, 8 bytes of data. If we edit the 128-bit command in units of 16-bit, 32-bit, and 64-bit, the old 16-bit processor, for example, the intel 80286 CPU needs 8 commands, A 32-bit processor requires four commands, while a 64-bit processor requires only two comma

The operands can be General registers or immediate numbers. Field is used to set the bit to be operated in the Program Status Register. As you can see, the 32bits of the dsrs can be divided into four domains. F S x C MSR cps

components, such as storage and IO devices. CPU The CPU consists of four main components: Arithmetic logical operation unit (ALU): This is the basic module of the CPU. It performs arithmetic operations and logical operations such as addition, subtraction, and Boolean operations (and or not ). Control unit: A digital circuit that controls CPU operations and coordinates CPU functions. Register: indicates a set of storage units. reg

processed by most applications.Due to the limitation of the number of digits of the AD converter, the dynamic range of the input signal is generally relatively small. However, in the signal processing of the DSP, the dynamic range of the signal of the intermediate node is increased due to the dot product operation, therefore, the DSP is selected based on the dynamic range of intermediate results in the signal processing process and the accuracy requirements of the algorithm for intermediate res
