Figure 20. The Parallel Instruction Fetches and Instruction Executions
Figure 21 shows the internal timing concept for the register file. In a single clock cycle
an ALU operation using two register operands is executed and the result is stored back
to the destination register.
Figure 21. Single Cycle ALU Operation
The internal data SRAM access is performed in two System Clock cycles as described
Figure 22. On-chip Data SRAM Access Cycles
See “Interface to External SRAM” on page 60 for a description of the access to the
external SRAM.
