TX19 Core Features

The TX19 is an exceptionally compact, high-performance processor at

20Mips and is available as an ASIC-ready core as well as a standard

product. Based on MIPS

TX19 offers the performance of a 32-bit RISC processor while deliver-

ing the compact code size associated with a 16-bit instruction set.

Using an optimized interrupt circuitry, the TX19 is ideal for embedded

applications requiring real-time interrupt response.

• 5-Stage Pipeline

• MIPS 32-/16-Based

• Non-Blocking Load

• Data Cache: 1Kbyte, 2-Way S/A, Write-Thru

• Instruction Cache: 4Kbyte, 2-Way S/A

• 4-Cycle MAC

• Direct Segment Mapping MMU

• DRAM, ROM, DMA and Interrupt Controller
