SPRS370E – SEPTEMBER 2006 – REVISED JULY 2008
The C672x DSP executes code directly from a large on-chip 32K-byte program cache. The program cache
has these key features:
• Wide 256-bit path to internal ROM/RAM
• Single-cycle access on cache hits
• 2-cycle miss penalty to internal ROM/RAM
• Caches external memory as well as ROM/RAM
• Direct-mapped
• Modes: Enable, Freeze, Bypass
• Software invalidate to support code overlay
The program cache line size is 256 bits wide and is matched with a 256-bit-wide path between cache and
internal memory. This allows the program cache to fill an entire line (corresponding to eight C67x+ CPU
instructions) with only a single miss penalty of 2 cycles.
The program cache control registers are listed in Table 2-4.
Table 2-4. Program Cache Control Registers
REGISTER NAME
BYTE ADDRESS
DESCRIPTION
L1PISAR
0x2000 0000
L1P Invalidate Start Address
L1PICR
0x2000 0004
L1P Invalidate Control Register
CAUTION
Any application which modifies the contents of program RAM (for example, a program
overlay) must invalidate the addresses from program cache to maintain coherency by
explicitly writing to the L1PISAR and L1PICR registers.
The Cache Mode (Enable, Freeze, Bypass) is configured through a CPU internal register (CSR, bits 7:5).
These options are listed in Table 2-5. Typically, only the Cache Enable Mode is used. But advanced users
may utilize Freeze and Bypass modes to tune performance.
Table 2-5. Cache Modes Set Through PCC Field of CSR CPU Register on C672x
CPU CSR[7:5]
CACHE MODE
000b
Enable (Deprecated - Means direct mapped RAM on some C6000 devices)
010b
Enable - Cache is enabled, cache misses cause a line fill.
011b
Freeze - Cache is enabled, but contents are unchanged by misses.
100b
Bypass - Forces cache misses, cache contents frozen.
Other Values
Reserved - Not Supported
CAUTION
Although the reset value of CSR[7:5] (PCC field) is 000b, the value may be modified
during the boot process by the ROM code. Refer to the appropriate ROM data sheet
for more details. However, note that the cache may be disabled when control is
actually passed to application code. Therefore, it may be necessary to write '010b' to
the PCC field to explicitly enable the cache at the start of application code.
CAUTION
Changing the cache mode through CSR[7:5] does not invalidate any lines already in
the cache. To invalidate the cache after modifications are made to program space, the
control registers L1PISAR and L1PICR must be used.
