Direct addressing mode is when the register address is available in the operand of the instruction. An example of an instruction

The host writes a byte of data into the data-out register, and sets the write bit in the command register

A 32-bit program can process 32 bits of data at once enabling a 32-bit program to do all calculations in one operation. This speeds the processing of your data.

Short-term: First it selects a process that’s already in memory and ready to execute. Then it allocates the CPU to it.

assign process identification, allocate address space, initialize process control block, set appropriate linkage, create or expand data structure

Memory segmentation is the division of a computer's primary memory information into sections. Segments are applied in object records of compiled programs when linked together into a program image and when the image is loaded into the memory. Segmentation sights a logical address as a collection of segments. Each segment has a name and length. With the addresses specifying both the segment name and the offset within the segment. Therefore the user specifies each address by two quantities: a segment name and an offset. When compared to the paging scheme, the user specifies a single address, which is partitioned by the hardware into a page number and an offset, all invisible to the programmer. Memory segmentation is more visible

i)Memory address register(MAR), which specifies the address in memory for the next read or write

More bits indicates the system can address a bigger amount of location in the installed physical memory.

Assembly language uses a mnemonic to represent each low-level machine operation or opcode. Some opcodes require one or more operands as part of the instruction, and most

Going back to our example above, the "MULT" command could be divided into three separate commands: "LOAD” (data is moved to a register from the memory bank), "PROD" (the product of two operands located within the registers is found), and "STORE" (data is moved from a register to the memory banks). Four lines of assembly would be needed in order to perform the same steps described in the chap-ter

This chip provides sequential read operation on whole chip. Program command is executed on byte basis, or page (256 bytes) basis, or word basis for erase command is executed on sector (4K-byte), block (32K-byte), or block (64K-byte), or whole chip basis. This chip can store up to 100,000 programs and erase cycles efficiently. [6]

data table which houses all the static variables necessary for the program to run is generated and stored in RAM [1]. A few benefits that exist when the variable data is stored this way include the fact that the variable data can be accessed easily by multiple programs or several times from the same program for reading [1].

The execution module is portrayed in Figure 3.7. Two 64 x 16 double port irregular access recollections (RAMs) are utilized. The invalid subcarriers are accomplished by characterizing the substance of the two RAMs at relative locations to be zeros. Ports An of the RAMs are utilized for information transporter composing, while ports B are committed for pilot composing and the 64-subcarrier perusing. They are controlled by two counters. "Counter_We_48" square stores the 48 information transporter positions. As per the locations indicated by it, the I and Q estimations of the information images are built into two RAMs from ports A. In the meantime, FFT movement is inalienably performed. "Counter_Rd_64" utilizes a counter to create the perusing locations of ports B. At the point when ports B are empowered and "Counter_Rd_64" tallies from 0 to 63, the coveted 64 inputs for IFFT are yielded and the "en_ifft" is high, telling the IFFT square to perform figuring.
