"Starting from scratch CPU Learning Chapter 07" The simplest alu-full-add device

The ALU is an arithmetic logical unit that is an important part of the CPU because the CPU is essentially repeating the simplest computations. And our version of the CPU of the ALU part is more simple, is a can only add the ALU. Theoretical part We need a circuit design that can help us with our mathematical calculations . Once you get through this, you can s

How do you understand the advantages of the Alu?

The ALU is a combinational logic circuit. The Arithmetic logic unit (arithmeticlogical) is the unit of execution of the central processor (CPU), which is the core component of all central processing units, and is composed of "and gate" (and gate) and "or gate" (or gates) of the arithmetic logic unit, The main function is to perform two-bit arithmetic operations, such as addition and subtraction (excluding integer division). Basically, in all modern C

traditional Vs and the ALU in PS (arithmetic logical unit, usually each vs or PS has An ALU, but this is not certain, for example, G70 and r5xx have two) you canWithin a period (that is, at the same time. For example, if you run a 4D command, the PS or ALU in vs calculates the four attribute data corresponding to the specified point and pixel of the command. The

R700 Instruction Set Architecture Reference Manual-Chapter 2: program organization and status

The r700 program consists of control flow (CF), Alu (arithmetic logic unit), texture retrieval, and vertex retrieval commands. Alu can have up to three source operations and one destination operation. Command to operate 32-bit or 64-bit IEEE floating point values and signed or unsigned integers. The execution of some commands causes the predicate bit to be written, thus affecting Subsequent commands. Graphi

stage (EX) by the Alu component. So, at the latest at 600PS, the number of T0 registers to be written is done. So, from a time point of view, after 600ps, we can get the latest value of the T0 register. And for this addition instruction, it really needs to use the value of the T0 register in its execution phase, that is, the ALU component needs to use the value of T0 as one of the inputs, that this stage i

6.5 Control signal of the branch instruction

the corresponding control signals.Again, we look directly at the second step. So for this step, the actions to be taken include removing the contents of two registers from the register heap, and doing the subtraction operation, which is the same as the requirements of the subtraction command we learned earlier. As a result, the existing structure does not need to be modified to complete this function. We note that when retrieving an instruction, the RS bit field is connected to the register hea

example of SPMD. In the hardware structure, multiple ALU instances are bound together to share a PC (Program Counter) to form a SPMD computing unit, such as the smx of the nv gpu, amd gpu Cus are all SPMD computing units. The number of ALU contained in a SPMD operation unit determines the theoretical maximum number of parallel threads. To simplify the hardware structure and reduce power consumption, the SP

The CPU kernel is mainly divided into two parts: the memory generator and the Controller. (1) Inspector1. Arithmetic Logic Operation Unit Alu (arithmetic and logic unit)ALU performs Fixed-Point Arithmetic Operations (addition, subtraction, multiplication, division), logical operations (same as or not), and shift operations on binary data. In some CPUs, there is also a locator dedicated for processing shift

, the address of the next instruction should still be in the pc+4 way. Then we look at this side of the register heap, both RS and RT are fixed connected to the corresponding bit field of the instruction encoding, so the BusA and Busb are the contents of the registers specified by RS and RT, respectively.But we should note that for this instruction, we want to calculate the addition of the contents of the RS register and the symbol extension of the immediate number. Therefore, for the source of

The story of "segment register" (mainly in the third segment)

I. Generation of segment registers The generation of segment registers is due to the inconsistent width between the data bus and the address bus in the Intel 8086 CPU architecture. The width of the data bus, that is, the width of the ALU (arithmetic logical unit). Generally, a CPU is "16-bit" or "32-bit. The data bus of the 8086cpu is 16 bits. The address bus width does not have to be the same as the ALU w
