3.1
This LSI incorporates a DSP unit and XY memory directly connected to the DSP unit. This LSI
supports the DSP extended function instruction sets needed to control the DSP unit and XY
memory. The DSP extended function instructions are classified into four groups (figure 3.1).
Extended System Control Instructions for the CPU: If the DSP extended function is enabled,
the following extended system control instructions can be used for the CPU.
• Repeat loop control instructions and repeat loop control register access instructions are added.
• Modulo addressing control instructions and control register access instructions are added.
• DSP unit register access instructions are added. Some of the DSP unit registers can be used in
Data Transfer Instructions for Data Transfers between DSP Unit and On-Chip XY
Memory: Data transfer instructions for data transfers between the DSP unit and on-chip XY
memory are called double-data transfer instructions. Instruction codes for these double-transfer
instructions are 16-bit codes as well as CPU instruction codes. These data transfer instructions
perform data transfers between the DSP unit and on-chip XY memory that is directly connected to
the DSP unit. These data transfer instructions can be described in combination with other DSP
unit operation instructions. For details, refer to section 3.4, DSP Data Transfer Instructions.
Data Transfer Instructions for Data Transfers between DSP Unit Registers and All Virtual
Address Spaces: Data transfer instructions for data transfers between DSP unit registers and all
virtual address spaces are called single-data transfer instructions. Instruction codes for the double-
transfer instructions are 16-bit codes as well as CPU instruction codes. These data transfer
instructions performs data transfers between the DSP unit registers and all virtual address spaces.
For details, refer to section 3.4, DSP Data Transfer Instructions.
DSP Unit Operation Instructions: DSP unit operation instructions are called DSP operation
instructions. These instructions are provided to execute digital signal processing operations at
high speed using the DSP. Instruction codes for these instructions are 32 bits. The DSP
operation instruction fields consist of two fields: field A and field B. In field A, a function for
double data transfer instructions can be descried. In field B, ALU operation instructions and
multiply instructions can be described. The instructions described in fields A and B can be
executed in parallel. A maximum of four instructions (ALU operation, multiply, and two data

the same way as the CPU system registers. For details, refer to section 3.4, DSP Data Transfer
Instructions.
