2.2.1 Features
2.1 Introduction
2.2 Overview: ARM920T Core
2ARM920T Core and Advanced High-Speed Bus (AHB)
This chapter describes the ARM920T Core and the Advanced High-Speed Bus (AHB).
The ARM920T is a Harvard architecture core with separate 16 kbyte instruction and data
caches with an 8-word line length. The ARM Core utilizes a five-stage pipeline consisting of
fetch, decode, execute, data memory access, and write stages.
Key features include:
• ARM V4T (32-bit) and Thumb (16-bit compressed) instruction sets
• 32-bit Advanced Micro-Controller Bus Architecture (AMBA)
• 16 kbyte Instruction Cache with lockdown
• 16 kbyte Data Cache (programmable write-through or write-back) with lockdown
• Write Buffer
• MMU for Microsoft Windows CE and Linux operating systems
• Translation Look-aside Buffers (TLB) with 64 Data and 64 Instruction Entries
• Programmable Page Sizes of 64 kbyte, 4 kbyte, and 1 kbyte
• Independent lockdown of TLB Entries
• JTAG Interface for Debug Control
• Co-processor Interface
