ARM Operating Modes The ARM processor has seven different modes of operation. Each of the ARM operating modes has a specific purpose, and only one mode is active at any one moment. Table 1 shows the 7 important ARM operating modes, which define the registers that may be used (also known as the register map) …
Pipelining in ARM
ARM Registers Basically there are two types of registers – General purpose registers and Special purpose registers. General-purpose registers hold either data or an address. The letter r is prefixed to the register number to identify them. For example, the label r4 is assigned to register 4. Figure depicts the active registers that are available …
CPSR and SPSR in ARM The ARM architecture supports two program status registers. The current program status register (CPSR) and the stored program status register (SPSR) are the two registers (SPSR). Click here to access to full ARM series. The CPSR in ARM is used to monitor and control internal operations. The CPSR is a …
ARM Core Dataflow Model The article deals with the explanation of the ARM core dataflow model. It also covers the complete implementation of architecture of the ARM processor(Complete ARM series ). As depicted in figure, an ARM core dataflow model may be thought of as functional units connected by data buses, with the arrows representing …
CISC vs RISC Architecture “Complex Instruction Set Computing” is the abbreviation for CISC This is a design for a microprocessor. The CISC architecture comprises a significant number of computer instructions that range in complexity and specialization from simple to complicated and specialized. Though the architecture was meant to calculate complicated instructions as quickly as possible, …

CPU CPU is one of the important parts of the PIC16f877a architecture. The CPU consists Arithmetic logic unit (ALU), a memory unit (MU), a control unit (CU), Accumulator. ALU performs arithmetic and logical operations, MU stores …
Introduction to PIC 16f877a PIC stands for Peripheral Interface Controller. It can be programmed using flash memory technology, this lets stored data be electrically erased and reprogrammed, making this microcontroller very convenient and widely used in a huge number of devices like remote sensors, security and safety devices and home automation. This microcontroller is pretty …
Infill 3D Printing What is Infill 3D printing? 3D printing has two zones, the shell and the fill. The shell refers to the outer walls of the model, whereas the fill or infill 3D printing refers to the amount of material inside the piece printed. A higher infill provides more strength, but at the cost …
