Functional description
Details of the LPC2210 systems and peripheral functions are described in the
following sections.
6.1 Architectural overview
The ARM7TDMI-S is a general purpose 32-bit microprocessor, which offers high
performance and very low power consumption. The ARM architecture is based on
Reduced Instruction Set Computer (RISC) principles, and the instruction set and
related decode mechanism are much simpler than those of microprogrammed
Complex Instruction Set Computers. This simplicity results in a high instruction
throughput and impressive real-time interrupt response from a small and
cost-effective processor core.
Pipeline techniques are employed so that all parts of the processing and memory
systems can operate continuously. Typically, while one instruction is being executed,
its successor is being decoded, and a third instruction is being fetched from memory.
The ARM7TDMI-S processor also employs a unique architectural strategy known as
THUMB, which makes it ideally suited to high-volume applications with memory
restrictions, or applications where code density is an issue.
The key idea behind THUMB is that of a super-reduced instruction set. Essentially,
the ARM7TDMI-S processor has two instruction sets:
The standard 32-bit ARM set.
A 16-bit THUMB set.
The THUMB set’s 16-bit instruction length allows it to approach twice the density of
standard ARM code while retaining most of the ARM’s performance advantage over a
traditional 16-bit processor using 16-bit registers. This is possible because THUMB
code operates on the same 32-bit register set as ARM code.
THUMB code is able to provide up to 65% of the code size of ARM, and 160% of the
performance of an equivalent ARM processor connected to a 16-bit memory system.
6.2 On-Chip static RAM
On-Chip static RAM may be used for code and/or data storage. The SRAM may be
accessed as 8-bits, 16-bits, and 32-bits. The LPC2210 provides 16 kB of static RAM.
6.3 Memory map
The LPC2210 memory maps incorporate several distinct regions, as shown in the
following figures.
In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in
either on-chip boot-loader, external memory BANK0 or on-chip static RAM. This is
described in
Section 6.19 “System control”
