APAKAH MAKSUD MICROINSTRUCTION dalam CORSICA?
Microcode
Microcode adalah lapisan arahan peringkat perkakasan atau struktur data yang terlibat dalam pelaksanaan arahan kod mesin peringkat tinggi dalam unit pemprosesan pusat, dan dalam pelaksanaan logik dalaman banyak pengawal saluran, pengawal cakera, pengawal antara muka rangkaian, pemproses rangkaian, unit pemprosesan grafik, dan perkakasan lain. Ia tinggal dalam memori berkelajuan tinggi khas dan menerjemahkan arahan mesin ke dalam urutan operasi peringkat litar terperinci. Ia membantu memisahkan arahan mesin dari elektronik asas supaya arahan boleh direka dan diubah dengan lebih bebas. Ia juga menjadikannya sesuai untuk membina arahan berbilang langkah yang rumit sementara masih mengurangkan kerumitan litar elektronik berbanding dengan kaedah lain. Menulis mikrokod sering dipanggil mikroprogramming dan mikrokod dalam pelaksanaan pemproses tertentu kadang-kadang dipanggil mikroprogram. Mikrood moden biasanya ditulis oleh seorang jurutera semasa fasa reka bentuk pemproses dan disimpan dalam struktur ROM atau PLA, atau gabungan kedua-duanya. Walau bagaimanapun, mesin juga wujud yang mempunyai beberapa mikrokod yang tersimpan dalam SRAM atau memori kilat.
Definisi microinstruction dalam kamus Corsica
Takrif mikroinstruktur dalam kamus adalah arahan yang dihasilkan dalam unit aritmetik dan logik sesuai dengan mikroprogram, yang mengaktifkan litar tertentu untuk melaksanakan sebahagian operasi yang ditentukan oleh arahan mesin.

Fundamentals of Computer Organization and Architecture
A microinstruction is a vector of bits, where each bit is a control signal, condition
code, or the address of the next microinstruction. Microinstructions are fetched
from CM the same way program instructions are fetched from main memory (Fig.

Computer Architecture: Pipelined and Parallel Processor Design
The opcode provides an initial address to an entry (microinstruction), which
specifies the control point values as well as the expected address of the next
microinstruction. During the process of instruction execution, the next
microinstruction ...
There are two important factors that must be considered while designing the
microprogram sequencer : • The size of the microinstruction and • The address
generation time The size of the microinstruction should be rninimum so that the
size of ...

There are many differences in the implementation of microprogramming between
the Honeywell and IBM systems, connected with sequencing schemes and the
basic sub-command and microinstruction structure. The ROM in the H-4200 ...

Computer Organisation and Architecture
A similar sequence of operations takes place at the lower microinstruction level,
where the control-unit continuously executes microinstruction cycles as follows :

Principles of Computer Hardware
Information in the microinstruction register is divided into four fields: next
microinstruction address field, micro- program counter load control field,
condition select field, and CPU control field. Most of the bits in the microinstruc-
tion register ...

1n the vertical (or packed) microinstruction, the instruction is divided into several
fields, each field corresponding to either a resource or a function in the
processing hardware. (1n the design of ASC MCU, each field corresponded to a
resource ...

Computer Architecture: Software Aspects, Coding, and Hardware
The first microinstruction is fetched into the uIR and the uPC is increased by one.
Enable bits in the first microinstruction route the address of the target instruction (
add) from PC to the address bus and initiate a memory read request. 2.

It is almost impossible to find a unique bit pattern, which can not be extracted
from the reconfiguration bitstreams, thus used as endop microinstruction.
Therefore, it is possible, that a reconfiguration microcode loading is terminated
earlier.
