High-performance Embedded Workshop V.4.09 Release Note

(6) Trace function (only for the SH3, SH3E, and SH-3DSP)

• FPU, MAC, or DSP register access information

When an instruction is executed to write data in the FPU, MAC, or DSP register, the simulator/debugger

does not display access information in the trace information.

• Pipeline display

For instructions that programming manuals do not describe as writing back data to registers, and if data is

written to registers as a result of the execution of such instructions, the simulator/debugger displays such an

operation as a stage of memory access and write back in the trace information. The numbers of cycles are

correctly displayed.

(7) H8SX Simulator/debugger

H8SX Simulator/debugger does not support Middle mode of H8SX CPU.

(8) Selection of the simulator target

When you create a project, select the simulator target corresponding to the CPU and the operating mode.

(9) Internal RAM area in the SH2A-FPU simulator/debugger

Though the memory map of the SH2A-FPU simulator/debugger shows addresses 0xFFF80000 to

0xFFFBFFFF as the internal RAM area, the range of 0xFFFA0000 to 0xFFFBFFFF are actually reserved.

For this reason, note the followings when using the SH2A-FPU simulator/debugger:

• Only use the range of 0xFFF80000 to 0xFFF9FFFF as the internal RAM area.

• When a stack area is to be assigned to the internal RAM area, set the initial stack-pointer value so that it will

be within the range of 0xFFF80000 to 0xFFF9FFFF.

(10) Saving workspaces for older versions of the High-performance Embedded Workshop

In High-performance Embedded Workshop V.4.04 and later versions, workspaces can be saved in the format

compatible with older versions of the High-performance Embedded Workshop. Note, however, that the

operation of the simulator/debugger may be extremely slow. If you intend to use this new feature, set the

trace capacity as 32,768 or less.

1.14 Windows and dialog boxes

1.14.1 Scrolling

(1) Up-scrolling may not be available with an intelligent mouse. In this case, use a scrolling button on the

window.

(2) If your PC has a touchpad with a scroll zone, scrolling the [Disassembly] window or the [Editor] window in

the mixed or disassembly mode while pressing the mouse or touchpad button may cause an application error.

Do not use the touchpad-scroll feature on the [Disassembly] or [Editor] window while pressing the mouse or

touchpad button.
