The RL78 family is an accumulator-based register-bank CISC instruction set architecture (ISA). [2] Although it has eight 8-bit registers or four 16-bit register pairs, essentially all arithmetic operations are performed on a single accumulator (the A register or AX register pair).
On an accumulator-based architecture machine, this may be a dedicated register. On a machine with multiple general-purpose registers , it may be a register that is reserved by convention, such as on the IBM System/360 through z/Architecture architecture and RISC architectures, or it may be a register that procedure call and return instructions ...
In a computer's central processing unit (CPU), the accumulator is a register in which intermediate arithmetic logic unit results are stored.. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to cache or main memory, perhaps only to be read right back again for use in the next operation.

The 6100 is a 12-bit CPU that closely emulates the PDP-8 (See PDP-8 for a more complete discussion). It has three primary registers: PC (program counter), 12-bit AC (accumulator), and MQ (Multiplier Quotient). All two-operand instructions read the AC and MQ and write back to the AC.
Revised HuC6280A. The HuC6280 8-bit microprocessor is Japanese company Hudson Soft's improved version of the WDC 65C02 CPU, an upgraded CMOS version of the popular NMOS-based MOS Technology 6502 8-bit CPU (the latter is essentially a simplified, less expensive and faster version of Motorola's 6800 design), manufactured for Hudson by Seiko Epson and NEC.
It is based on the 8/16-bit WDC 65C816, which was developed between 1982 and 1984 for the Apple IIGS personal computer. It has 92 instructions, an 8-bit data bus, a 16-bit accumulator, and a 24-bit address bus. The CPU runs between 1.79 MHz and 3.58 MHz, and uses an extended MOS Technology 6502 instruction set.
And I will say, one of my children may have a little less than the others!” “I won’t say his name,” Hoda teased, referring to Jenna’s only son, Hal, 5. Jenna and her husband, Henry Hager ...
