Overview and Features
Overview and Features
The TX19 family is a high-performance 32-bit RISC processor series that TOSHIBA originally developed by
integrating the MIPS16
efficiency.
TMP19A44 is a 32-bit RISC microprocessor with a TX19A/H1 processor core and various peripheral functions
integrated into one package. It can operate at low voltage with low power consumption.
Features of TMP19A44 are as follows:
(1) TX19A/H1 processor core (refer to the separate volume “19A/ H1 Architecture” for details.

High performance
Low power consumption
Improved code efficiency and operating performance have been realized through the use of two ISA
(Instruction Set Architecture) modes - 16- and 32-bit ISA modes.
•
•
Both high performance and low power dissipation have been achieved.
•
•
•
•
•
•
•
•
High-speed interrupt response suitable for real-time control
•
•
•
The 16-bit ISA mode instructions are compatible with the MIPS16
code efficiency at the object level.
The 32-bit ISA mode instructions are compatible with the TX39 instructions of superior operating
performance at the object level.
Almost all instructions can be executed with one clock.
High performance is possible via a three-operand operation instruction.
3-stage pipeline
Built-in high-speed memory
DSP function: A 32-bit multiplication and accumulation operation can be executed with one clock.
On-board floating-point unit (FPU)
Optimized design using a low power consumption library
Standby function that stops the operation of the processor core
Independency of the entry address
Automatic generation of factor-specific vector addresses
Automatic update of interrupt mask levels
