I will upload my new book, "Write My Own processor" (not yet published), today is the third article. I try four articles a week.MIPS instruction set architecture since the advent of the 80 's. has been upgrading, from the initial MIPS I to MIPS V, to support the expansion module MIPS32, MIPS64 series, and integrated code compression technology microMIPS32, microM
MIPs instruction set architecture
The instruction set architecture ISA is fully called the instruction set architecture. MIPS has been continuously expanded since it was proposed in 1988. Its ISA is roughly as follows:
MIPs IThis
Detailed instructions are given below:
$: That is $zero, the register always returns zero, providing a concise coding form for the useful constant of 0.
Move $t 0, $t 1
Actually for
Add $t 0,$0, $t 1
Using pseudo-directives can simplify tasks, and assembler provides a richer set of instructions than hardware.
$: That is $at, the Register is reserved for assembly, because the immediate number field of type I instruction is only 16 bits, whe
a single operation of the MIPS CPU can load or store 1 to 8 bytes of data. The multiplication result registers are interlocked (interlocked) Because the result of the multiplication is not enough to allow the next instruction to automatically get the result. Attempting to read the result register before the multiplication operation completes causes the CPU to stop running until it is complete. One of the go
In Angular. JS, the instruction reference template and instruction are described as attributes. angular. jstemplate

Commands can be simply understood as functions running on specific DOM elements. commands can extend the functions of these elements.
The command must take effect.

Csapp, the third edition of "in-depth understanding of computer systems: A programmer's Perspective", is a good book, but it needs to be quite basic in reading. Moreover, some of the expressions are not straightforward.For example, the No. 463 page mentions why the assembler sets the initial value of the reference in the call instruction to-4 (for 32-bit systems). Explained vague later. In conjunction with

PHP needs to end the instruction with a semicolon after each statement.An end tag in a PHP code implies a semicolon; the last line in a PHP snippet can end without a semicolon.If there are new rows later, the end tag of the snippet contains the end of the line.The end tag of the PHP snippet at the end of the file can be omitted, and in some cases it would be better to omit it when using include or require-avoid unnecessary whitespace characters.PHP Ma
