1.5 Features
This section describes the features specific to the Universal model QCPU.
(1) High-speed processing more than ever
The processing time required for the basic instructions, floating-point operations, and accesses to the file register
becomes shorter than the existing Q series CPU modules.
Use of a standard device register (Z)
*1
achieves high-speed processing between register operations (transfer
instruction).
*1: An index register used between register operations is designated as a standard device register.( Section 9.6.2)
(2) Large-capacity file register
The file register whose capacity is 640K points
at maximum (4086K points at maximum when a memory card is
used)
*2
can be set inside the CPU module.
*2: For the Q26UDHCPU and Q26UDEHCPU only
(3) Use of double-precision floating-point operation instructions
The double-precision floating-point operation instructions (64-bit instructions) are available as well as the existing
single-precision floating-point operation instructions. ( Section 2.4.4)
This enables more accurate analog control and positioning control.
(4) Using the file register area as the data register and link register
The file register (ZR) area can be used as an pseudo extended area
*3
of the data register (D) and link register
(W). ( Section 9.8)
Programming using the extended data register (D) or extended link register (W) whose capacity is 640K points at
maximum (4086K points at maximum when a memory card is used)
*4
is available in addition to the internal user
device.
*3: Extended areas of the data register (D) and link register (W) are called the extended data register (D) and extended link
register (W), respectively.
*4: For the Q26UDHCPU and Q26UDEHCPU only
